NSK BSF40100DDUHP2B R BE4L5 2 Row Ball Screw Support Bearing - 40 mm ID, 100 mm OD 34 mm Race Width

Ball Screw Support Bearings - BSF Series

The BSF series of bearings is equivalent to the BSN range of bearings, with an extended outer ring, with bolt holes for easy direct mounting. Relubrication holes in outside surface and face of the outer ring allow for relubrication during operation if necessary. The holes are closed off with set screws. An extraction groove on the outer surface of the outer ring aids removal of the bearing.

BSF-DT Series

The matched DT pairs are essentially the same as the individual bearings. The two individual bearings have been matched together in the paired version. Some sizes also have extra fixing holes in the outer diameter. Both bearings have a V-shaped mark on the outer diameter to ensure that they are arranged correctly.
