Thrust roller bearings for main shaft axial load, radial joint load, but the radial load shall not exceed 55% of axial load. Thrust roller bearings other than the low friction coefficient of such bearings, high speed and with self-aligning properties. 29000 non-stick type bearings spherical roller symmetrical type, can reduce the roller and raceway relative sliding at work, and the roller length, diameter, and the number of multi-roller, high load capacity, usually in oil lubrication, Grease can be used for individual low-speed situations. Selection in the design whenPreference should be given; 80000 Thrust cylindrical roller bearings, 90000 Thrust tapered roller bearings and thrust needle bearing AXK type, can withstand a one-way axial load, thrust ball bearings than the axial load capacity of a much larger and rigidity, occupying a small axial space. Thrust cylindrical roller bearings and thrust needle roller bearings suitable for low speed situations, thrust tapered roller bearings speed slightly higher than the thrust cylindrical roller bearings.

Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) loads.Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load and axial component force will be produced with must be counteracted. So the bearings are normally adjusted against a second bearing. Single row angular contact ball bearings can carry axial load acting in one direction only. In many applications, angular contact ball bearings in pairs or multi-arrangement should be used. That the axial load carry capacity of angular contact ball bearings increase with the increase of contact angle.

Cylindrical roller bearings are separable, and it is easy to be installed and disassembled. The linear contact between cylindrical rollers and raceway make cylindrical roller bearings capable of large load, both radial and impact. Cylindrical roller bearings are suitable for high speed rotation.According to the rows of rollers, this kind of bearings can be divided into single row, double row, four low and various transformational structures. Cylindrical roller bearing are used in all kinds of motors, generators, gas tune machines, machine tool spindles, speed reducer, and handling machineries, while four roller bearings usually apply to rolling mills.

We offer self-aligning roller bearing has two rows of spherical rollers, the outer race is provided with a common concave spherical raceway, while the inner race is provided with two concave spherical raceways that form an angle with the bearing axis. The curvature center of the outer raceway is consistent with the bearing center. the self-aligning roller bearing is self-adjusted, and it is not affected by non-centering or shaft deformation flexure of shaft and bearing block, so it can compensate the concentricity error caused by these reasons. Except being subject to radial load, this type of bearing can also be subject to bidirectional axial load and their combination load. The load capacity is large, and the bearing is provided with preferable shock resistant capacity. Self-aligning roller bearings are mainly applied on mechanical equipments of steel, mine, paper making, shipping, textile machinery, coal mill and electric power industries. It is one of the bearings most widely used in mechanical industry.

Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load. According to dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series. The following models are available at competitive prices: 30200 series; 30300 series; 31300 series; 32000 series; 32200 series; 32300 series; 33000 series; 33200 series; Inch series.

This type of bearings is separable, which can only carry axial load . The single direction bearings of them can only carry axial load in one direction, while the double an carry alternating axial load in either direction, Before using they have to be preloaded. The thrust ball bearings are used in lathe centers, automobile clutches, reducers and so on. The double direction angular contact thrust ball bearings are suitable for machine tool spindles, while the single are used to support ball screws.

Its are used in a particularly wide variety of applications. They are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. The inner and outer ring of single row deep groove ball bearings have a deep groove raceway, the bearings are mainly used to carry radial loads and a part of axial loads in two directions. This kind of bearing can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed angular contact ball bearings. Deep groove ball bearing have various types in structure, beside open type bearings, shield or seals at both side can also be provided.Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery, etc.

The self-aligning ball bearing has two rows of balls and a common concave sphere raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.Self aligning ball bearings are suitable for applications where misalignment can arise from errors in mounting or shaft deflection. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Accordingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted.Double row self-aligning ball bearings have a sphere raceway in the outer ring and a double raceway in the inner ring. This feature gives the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. They are therefore particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection. Double row self-aligning ball bearings are mainly used to carry radial loads and light axial loads, but cant carry pure axial loads.
