End bearings

A special design for a specific application High-precision Single Direction Angular contact thrust ball bearings have been developed especially for the support of ball and roller Screws in machine Tools. They incorporate a large number of balls and have a special internal design with a contact angle of 60° to provide superior axial stiffness. These bearings also have high axial load ratings, high running accuracy together with speed and acceleration capability and low frictional torque. Ready to mount units To simplify and speed up mounting, complete greased-for-life cartridge units are available in matched sets of two, three or four Single Direction Angular Contact Thrust Ball bearings in a flanged housing. These units are sealed and due to the flange can be simply bolted to the machine frame.

Double Direction Angular Contact Thrust Ball Bearings with and without integrated flange, sealed and greased for life are also a part of the product range.

Note: For other informations on the products please consult SKF BSS.
