Cylindrical Thrust Roller Bearings

Cylindrical thrust roller bearings are separable bearings, generally consisting of 2 washers (raceways) and cylindrical rollers. Cylindrical thrust roller bearings are separable. They only carry axial loads in 1 direction and slight shock loads, but their loading capacity is much higher than thrusting ball bearings with the exact dimensions. They can limit axial displacement of shafts or housing in 1 direction so that they can be axial locating bearings in 1 order. The slippage will be formed on the raceways because of the linear velocity differences between 2 ends of rollers while rolling. So the Limiting speed of these bearings is lower than thrust ball bearings, and they are usually applied to typical speed applications.

Types of cylindrical thrust roller bearings

cylindrical thrust roller bearings are available in a single direction and double direction configurations in the following design variants:

  • One row of rollers
  • Two rows of rollers

Cylindrical thrust roller bearings are divided into single row cylindrical thrust roller bearings and double row cylindrical thrust roller bearings according to the number of bearing roller rows. Single row cylindrical thrust roller bearings can withstand axial load and limit axial displacement in 1 direction. Double row cylindrical thrust roller bearings can bear the bidirectional axial burden and limit axial displacement in both directions.

Features of cylindrical thrust roller bearings

  • Separable design
    The shaft washer, housing washer, cylindrical roller, and cage thrust assembly can be mounted separately.
  • Extended bearing service life
    To prevent stress peaks, the roller ends are relieved slightly to modify the line contact between the raceway and rollers.

Applications of Cylindrical thrust roller bearings

Here are examples of applications in which cylindrical thrust roller bearings might be used:‚Äč

  • Material handling
  • Industrial transmissions
  • Machine tools
  • Trucks, trailers, and buses
