Linear components are as varied as the applications in which they are used. In transport and feed systems, it is mainly speed and accuracy that are required while, in measuring machines for example, the emphasis is more on precision and rigidity. In order to find the right linear guidance system for the specific task, both a sophisticated product range and detailed consultation are important. We offers both: a wide range of linear products, combined with expert service. Furthermore, a range of accessories precisely matched to applications allow even greater optimisation of the comprehensive standard versions of guidance systems.

Axial cylindrical roller bearings comprise axial cylindrical roller and cage assemblies and shaft and housing locating washers.The bearings have particularly small axial section height, have high load carrying capacity and high rigidity and can support axial forces in one direction.

Axial cylindrical roller and cage assemblies

Axial cylindrical roller and cage assemblies comprise axial cages with one or two rows of cylindrical rollers. The cage assemblies have particularly small axial section height, high load carrying capacity and high rigidity. They can support axial force from one direction and act as non-locating bearings in a radial direction. Axial cage assemblies are combined with housing or shaft locating washers or are integrated directly in the adjacent construction. If they are used without axial bearing washers, the raceway must be produced as a rolling bearing raceway.

Housing locating washers

Housing locating washers are produced by machining, the outside surface is ground and the running surface is high precision machined. They are housing located and are combined with axial cage assemblies if the adjacent surface cannot be used as a raceway.

Shaft locating washers

Shaft locating washers are produced by machining, the bore is ground and the running surface is high precision machined. They are shaft located and are combined with axial cage assemblies if the adjacent surface cannot be used as a raceway.

Bearing washers

Bearing washers can be used as housing and shaft locating washers. The bore and outside surface are turned, the running surface is ground

Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings and in single and double row designs.

X-life

Many sizes are supplied in X-life design. These bearings are indicated in the dimension tables.Bearings of X-life quality have a lower roughness Ra and superior geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, the load carrying capacity and life of these bearings is higher while maintaining the same dimensions. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary

Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.

Needle roller bearings are single or double row units comprising machined outer rings with ribs, needle roller and cage assemblies and removable inner rings. The bearings are available in open and sealed versions.

X-life

Needle roller bearings with ribs are X-life bearings. In these bearings, the roughness and geometrical accuracy of the raceways have been optimised. This gives higher load carrying capacity and longer life.

Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.

The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

Drawn cup needle roller bearings with open ends and with closed end are units comprising thin-walled drawn outer rings and needle roller and cage assemblies. Drawn cup need roller bearings with open ends are also available in full complement versions. The majority of the bearings are single row designs.

Drawn cup needle roller bearings with open ends and with closed end are available in open and sealed versions. Due to the thin-walled outer drawn cup and the absence of an inner ring, drawn cup needle roller bearings with open ends and with close end have an extremely low radial section height. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted. If shoulders, snap rings etc. are not used for axial location, the housing bore can be produced easily and particularly economically.

There is nothing that cannot be improved - Schaeffler developed the TB roller to significantly increase the bearing operating life under axial load. The special torus-shaped curvature of the end faces of this roller enables loads to be distributed across a significantly greater surface area.

Aligning needle roller bearings are units comprising drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings.The bearings can compensate static shaft misalignments and can thus tolerate misalignment of the shaft relative to the housing.Aligning needle roller bearings are firmly seated in the housing bore. The bore can therefore be produced easily and economically.

X-life

Aligning needle roller bearings are X-life bearings. In these bearings, the roughness and geometrical accuracy of the raceways have been optimised. This gives higher load carrying capacity and longer life.

Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.

Double direction axial angular contact ball bearings are non self-retaining precision bearings with restricted tolerances to class SP. They comprise solid shaft locating washers, spacer rings, housing locating washers and ball and cage assemblies with solid brass cages. The parts of the bearings are matched to each other and can be fitted independently of each other; they must not be interchanged with those of bearings of the same size.

Crossed roller bearings are bearings for precision applications that correspond in their dimensions to ISO dimension series 18 in accordance with DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.

Due to the X arrangement of the rolling elements, these bearings can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads with a single bearing position. This allows designs with two bearing positions to be reduced to a single bearing position. Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, little clearance or preload. The bearing outer rings can be easily located in the adjacent construction by means of clamping rings.

Spherical roller bearings are a special rolling bearing design whose inner ring runs inside the outer ring on two rows of rollers. The bearings have an angular adjustment of up to 2 and are not only designed for high load carrying capacity but can also compensate misalignments.The decades of experience our engineers have gathered combined with innovative ideas improve our spherical roller bearings even further. As a matter of fact, our quest for perfection in development and production ensures optimum kinematics and low wear, which increases the operating life even more. And that comes at a low maintenance outlay and minimum maintenance costs.

Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.

Four point contact bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. Due to the two-piece inner rings, a large number of balls can be accommodated. The halves of the inner ring are matched to the specific bearing and must not be interchanged with those of bearings of the same size. The outer ring with the ball and cage assembly can be fitted separately from the halves of the inner ring.

Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles. The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.

Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed versions. Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing arrangements of spindles in machine tools.

Ball roller bearings series BXRO are double row bearings whose rows of rolling elements are in an O arrangement. They can thus support both radial and axial forces.In comparison to series 32 ball bearings, up to 50% more rolling elements can be fitted in these ball roller bearings due to the innovative assembly method, which enables higher basic load ratings in the same space. The advantages of the BXRO compared with the 33 series (three ring bearings) lie in the simplified assembly as well as the increased bearing accuracy due to the optimized raceway geometry and the single-piece inner ring.

Thin section bearings have high precision, are very quiet and have high load carrying capacity. These ball bearings are available in three different designs and have an extremely small, predominantly square cross-section. Within each series, the cross-section remains constant even for larger shaft diameters and housing bores. The bearings are therefore also described as Constant Section (CS). This special feature distinguishes thin section bearings from conventional bearings as standardised in ISO series.It is therefore possible to select a larger cross-section and thus use a bearing with higher load carrying capacity without the need to change the shaft diameter as well. Thin section bearings allow designs to be achieved that are extremely light and require little space.

Single Row Ball Roller Bearings a higher load carrying capacity (C) than a standard ball bearing in the same space. This increase is attributed to 50 % more rolling elements (Z) that are fitted by means of innovative assembly methods. Thanks to the achieved rolling element filling capacity of more than 90 %, the BXRE bearing withstands even the most extreme loads.

The requirements placed on linear components are as varied as the applications in which they are used. In transport and feed systems, it is mainly speed and accuracy that are required while, in measuring machines for example, the emphasis is more on precision and rigidity.

We offers both: a wide range of linear products, combined with expert service. Furthermore, a range of accessories precisely matched to applications allow even greater optimisation of the comprehensive standard versions of guidance systems.

Each linear design has particular characteristics that make it especially suitable for particular bearing arrangements. Generally applicable rules for selecting the type of guidance system can only be formulated up to a point, since more and more factors must be taken into consideration and weighed up against each other. Apart from load, acceleration, speed and stroke, factors including temperature, lubrication, vibration, mounting, maintenance etc. must be taken into consideration.

Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design than these. They differ in the size of their contact angle and the design of the bearing rings.

The bearings are available in open and sealed versions. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields. Sealed bearings are maintenance-free and, as a result, allow particularly economical bearing arrangements. The self-alignment capacity of angular contact ball bearings is very small.

Axial deep groove ball bearings comprise shaft locating washers, housing locating washers and ball and cage assemblies. The bearings are not self-retaining; the ball and cage assembly and bearing washers can therefore be fitted independently of each other.In addition to series with flat washers, there are also series with spherical housing locating washers for compensation of static misalignment. These designs are normally used in comjunction with support washers. Axial deep groove ball bearings are available in single and double direction designs.Both designs can support high axial forces but must not be subjected to radial loads.

Needle roller bearings without ribs are single or double row units comprising machined outer rings without ribs, needle roller and cage assemblies and removable inner rings.The bearings are not self-retaining. This means that the outer ring, needle roller and cage assembly and inner ring can be fitted independently of each other.
