FAG QJ330-N2-MPA-C3 Four point contact bearings Bore diameter 150 mm Outside diameter 320 mm Rotational speed (max.) 380

Four point contact bearings are single row angular contact ball bearings. This means they come with a more slimline axial design than their double row counterparts. These bearings consist of robust outer races, two-part inner races, balls and retainers. Two-part inner races enable loading a large number of balls. Inner race parts have been custom manufactured for each bearing, and are not interchangeable between same-size bearings. Outer race including ball retainer and the two parts of the inner race can be separately assembled.

Postposed characters are used to identify different bearing types.
· C3, C4 = clearance rating
· MPA = robust brass cage
· TVP2 = robust PVC cage
· N2 = 2 retainers on outer race
