FAFNIR BALLSCREW SUPPORT BEARINGS

BSPB D Standard and Heavy Duty Bearings

The BSPB D series is a design of bearing pillow block unit for ballscrew applications.

The unit incorporates similar features to the BSBU D series but is designed to bolt down onto a flat surface, parallel to the ballscrew axis.

In the standard unit, pilot holes for dowels are provided. Units with finished holes for dowels can be supplied by special order if required.

Consult our Engineering Department for recommended shaft and housing fits.

STANDARD SERIES – DIMENSIONAL TOLERANCES .005" (.13mm) UNLESS OTHERWISE STATED.
