FAG 6311-2Z Deep groove ball bearings (axial) Bore diameter 55 mm Outside diameter 120 mm Rotational speed (max.) 5300 U

Deep groove ball bearings allow a wide range of uses. They consist of a robust outer race, inner race, balls and a retainer/cage. Deep groove ball bearings are both durable and low-maintenance. Their low-friction properties make deep groove ball bearings the preferred choice for parts rotating at high speed. They come in various types: single row, dual row, open, and closed. Closed deep groove ball bearings are greased-for-life bearings.

Postposed characters are used to identify different bearing types.
· Standard = no postposed characters
· M = bilateral groove seal
· Y = Brass cage
· 2Z = bilateral cover
· 2RS = bilateral lip seal
· C3, C4 = clearance rating
