Thrust Roller Bearing

Thrust roller bearings can accommodate heavy axial loads. Bearings of some structural groups can additionally accommodate slight radial load. They allow much lower rotational speeds as it is compared with other types of bearings.

Thrust roller bearings are available of the following design variants:

single direction bearings with cylindrical rollers and a solid cage.

single direction double-row bearings with cylindrical rollers and a solid cage. Two short rollers of varying lengths are installed into the pocket of the cage instead of one long roller in order to reduce the slippage

occurring between the rollers and ring raceways due to the difference of linear velocities.

bearings with cylindrical rollers without rings and with a solid cage. Hardness and accuracy of rolling surface in contact with the rolling surface of the rollers should be the same as that of the bearing rings.

bearings with needle rollers with one ring and a pressed cage.Hardness and accuracy of rolling surface in contact with the rolling surface of the rollers should be the same as that of the bearing rings.

double direction bearings with cylindrical rollers and a solid cage. Axial load in both directions is applied.

single direction taper roller bearings with ribs on shaft washer and housing washer with a solid cage.

single direction full complement taper roller bearings installed into the housing. The bearings have one flanged ring and one flat ring.

bearings with spherical rollers and solid or pressed cage. The bearings are subjected to heavy axial and light radial loads. They allow higher rotational speeds as compared with thrust roller bearings of other types. The bearings are self-aligned relative to the centre of spherical housing washer raceway. Solid cages are produced of nonferrous metal or steel.

Thrust roller bearings are used in rolling mills, globoid gears (cone-worm units), machine tool tables, swivel of oil-producing machines.
