Dependable shaft support for industrial machinery

Practical benefits

Secure mounting by Skf: The cast iron housing provides a rigid foundation that you bolt securely onto machine frames.
Firm eccentric collar locking: You achieve quick, slip-free locking on 50 mm shafts designed for single-direction rotational setups.
Tolerates initial shaft misalignment: The durable steel insert bearing accommodates moderate mounting misalignments for smooth, uninterrupted rotation.

In a nutshell

The right choise for

With the Skf fy 50 fm flanged bearing unit, you mount a 50 mm shaft securely onto machine frames, conveyor systems, or production lines. The durable cast iron housing provides a rigid base that bolts into place using four holes with a 111 mm center-to-center distance. Thanks to the eccentric locking collar, you achieve fast, slip-free shaft locking for constant rotational directions. The built-in steel bearing accommodates minor initial misalignments while handling speeds up to 4000 rpm. An integrated grease fitting makes routine relubrication simple for dependable, long-term operation.

Product description

These square flanged ball bearing units are compliant with ISO standards. They consist of an insert bearing, with a narrow inner ring and eccentric locking, and are intended primarily for use in applications where the direction of rotation is constant. The bearing is mounted in a cast iron housing, which can be bolted to a machine wall or frame. Ball bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.
