We provide three types special cylindrical roller bearings One Direction Locating Bearings, Two Direction Locating bearings and Full Complement Roller Bearings.

One Direction Locating Bearings
We offer one direction bearings that have separable outer or inner rings. The single flange of the separable ring prevents the bearing shaft from going in one direction. The double flanged race is guided by the roller guidance. They have a slightly lower limiting speed caused by the flange.

Two Direction Locating Bearings:
We supply two direction locating bearings that have a two piece inner ring or are self contained. These cylindrical bearings have a lower roller capacity but a high load capacity. They are rather complex bearings.

Full Compliment Bearings:
Full-complement Bearings use two snap rings in the non locating race to retain the rollers. These cylindrical bearings have high load capacity but low speed which is a result of the high rubbing velocity between adjacent rollers. This limits the bearings to low speed or oscillatory applications.

Physical Characteristics
A cylindrical shape would add to the stress concentrations at the end of the roller-race contact which results in high wear and high sensitivity to misalignment .Henceforth, they are usually crowned or end relieved.

Matched Pair bearings are Angular contact ball bearings that are suitable for applications that require high accuracy and high-speed performance. Bearings with a smaller contact angle are more suitable for high-speed rotation; those with a larger contact angle are more suitable for high load applications. Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance. For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is specified in three levels: light, medium, and heavy. Two bearings are used together facing one another or two or more bearings are matched and used.

andem arrangementA tandem arrangement is used when the load carrying capacity of a single bearing is inadequate. When arranged in tandem, the load lines are parallel and the radial and axial loads are equally shared by the bearings. Axial loads in both directions can be accommodated.

Back-to-back arrangementMounting two bearings back-to-back provides a relatively stiff bearing arrangement, which can also accommodate tilting moments. When arranged back-to-back, the load lines diverge towards the bearing axis. Axial loads in both directions can be accommodated, but only by one bearing in each direction.

Face-to-face arrangementMounting two bearings face-to-face is not as stiff as a back-to-back arrangement, but less sensitive to misalignment. When arranged face-to-face, the load lines converge towards the bearing axis. Axial loads in both directions can be accommodated, but only by one bearing in each direction.

"V-shaped" markingA "V-shaped" marking on the outside surface of the outer rings of matched bearings (fig. 5) indicates how the set should be mounted to obtain it's desired performance . The bearing pairs are supplied as a packaged unit.

Types of Needle Roller Bearings

• Drawn cup needle roller bearings:These needle roller bearings have a deep thin walled outer ring with open or closed ends. These bearings have a very low sectional height and have high load carrying capacity. They are used when a very compact arrangement is required and the housing bore cannot be used as a raceway. These drawn cup needle roller bearings are directly used on the shaft.
• Drawn cup needle roller bearings with closed ends:These drawn cup are manufactured of hardened steel sheet, needle roller and cage assembly form a non-separable unit. There drawn cup needles have a large lubricant space. Generally, they have only a single row of rollers but some may have two-needle roller and cage assemblies adjacent to each other with the lubricating hole in the outer ring.
• With and without inner rings:These are rubbing of polyurethane or nitride rubber(NBR).Superior quality of lithium base grease is used in them. They are a substitute for seals. The raceways of the shaft must have the hardness and the surface should have a normal finish in order to maximize the load carrying capacity.

Needle Roller Bearings Specifications & Standards

• Dimensions - The boundary dimensions of the drawn cup needle roller bearings are in accordance with ISO
• Bore Size - Its size is measured in millimeters. The bore is a hollow cylindrical chamber or barrel shaped where the metal balls are placed.
• Outer Ring Width - It is the width of the outer ring measured in millimeters.
• Revolutions - Revolutions indicate the rotation speed of the bearing.
• Bearing Weight It indicates the weight of the bearing, measured in pound.
• Tolerance - They are usually meant for normal tolerance but can be enhanced.
• Internal Clearance- A suitable internal clearance is achieved by selecting appropriate tolerance.
• Misalignment - The line contact between the raceways and the rollers prevent damaging edge stresses from occurring & also allows bearings to accommodate very minor angular misalignments of the shaft relative to the housing.
• Cages - There are standard cages but some may
