Ball bearings with four-point touch

Four-point ball bearings are single-handedly slip-bearing bearings and therefore require significantly less space in the axial direction compared to two-way ball bearings.

These bearings consist of an outer ring, a two-piece inner ball of balls and a cage that can be made of polyamide or brass. Due to the two-part inner ring, it is possible to accommodate a larger number of pellets. The parts of the inner ring are exactly defined for a particular bearing and as such can not be installed in another bearing of the same size. Installation of the outer ring, balls and cages can be done separately, regardless of the hemisphere of the inner ring.
