BMF Series - Fixed Angular Bearing Mounts

The BMF series bearing mounts are FIXED RIGID supports that utilize a set of spaced angular contact ball bearings. These bearing mounts are designed to support both radial and axial load components of force. Consult engineering for application assistance if required.

NOTE: Dimensions shown for screws without corresponding bearing mounts are for reference only.
