FAG BSB55120-SU-XL-L055 - Axial angular contact ball bearing BSB..-SU-XL, single direction, no screw mounting.
BSB55120-SU-XL-L055 FAG angular contact ball bearings for screw drives are single row precision bearings. They can support radial forces as well as axial forces in one direction. The bearing rings are matched to each other such that a defined preload is achieved when the rings are clamped in place using a precision locknut.
