Cylindrical Roller Thrust Bearings series 811 and 812 are single direction acting separable axial bearings.
Cylindrical roller thrust bearings are insensitive to shock loading and feature much higher load carrying capacity compared to thrust
ball bearings. They accommodate very high axial loads but no radial forces. They provide a very rigid bearing assembly for high thrust
loading with less space requirement.
Cylindrical roller thrust bearings are of simple design, they consist of a shaft washer (WS), a housing washer (GS), and a cylindrical roller
and cage thrust assembly (K), see Abb. 1.
With all cylindrical roller thrust bearings, increased sliding friction can occur at the end of the cylindrical rollers.
In order to minimize this negative effect, URB cylindrical roller thrust bearings with wider sectional widths are produced using severa
short rollers in each cage pockets instead of using individual longer rollers.
Due to their specific kinematic behavior, cylindrical roller thrust bearings are only suitable for low speed applications only.
Furthermore, they require minimal axial loads for their optimum function.
Design variants
URB cylindrical roller thrust bearings are produced in single direction design only as standard (see Abb. 1a)
