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.

1.) The BMF series bearing mounts are precision machined for foot mounting and pre-drilled for taper pins.

2.) The BMF series bearing mounts are to be considered as "FIXED" support for column loading and critical speed calculations.

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