FAG 31311-A Tapered roller bearing Bore diameter 55 mm Outside diameter 120 mm Rotational speed (max.) 5600 U/min

Tapered roller bearings consist of robust tapered outer and inner races, tapered rollers retained by a cage. This type of bearing is not self retaining. This allows fitting rollers/cage and outer race separately. Tapered roller bearings are able to withstand high radial and one-sided axial load. Generally a second bearing mirroring the first bearing is fitted to offset the load.

Postposed characters are used to identify different bearing types.
· A = modified inner components
· B = larger contact area
· X = outer dimensions comply with global standards
· P5 = tolerance raing
