SKF Spherical Roller Thrust Bearing 29256

Spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.

Depending on their series and size the spherical roller thrust bearings are manufactured to two basic designs:

Bearings with no designation suffix
Bearings with no designation suffix are fitted with a machined prong-type brass cage as standard. The cage is guided by a sleeve held in the shaft washer bore. The shaft washer, cage and rollers form a non-separable unit.

Bearings with an E designation suffix
E-design bearings have larger rollers and an optimized internal design for increased load carrying capacity.
E-design bearings up to size 68 are fitted with a stamped window-type steel cage, which forms a non-separable unit with the shaft washer and rollers.
E-design bearings from size 72 and larger are fitted with a machined prong-type cage. This type of cage is guided by a sleeve held in the shaft washer bore. The shaft washer, cage and rollers form a non-separable unit.
