FY20TR SKF 20mm Four Bolt Square Flanged Bearing Unit

Support a 20 mm shaft with the SKF FY 20 TR, which combines a cast iron square flange housing with a YAR 204-2RF insert ball bearing. The four-bolt flange mounts directly to a machine wall or frame, making the unit suitable for conveyors, material handling equipment and general machinery.

Set screws in the extended inner ring secure the bearing to the shaft. The unit is suitable for shafts that rotate in one direction or reverse direction during operation. Multiple contact seals and flingers on both sides help keep contaminants out and grease in. A grease fitting allows relubrication during routine maintenance.

The housing measures 86 × 86 mm, with mounting holes on 63.5 mm centres and an overall unit width of 37.3 mm. The bearing can accommodate moderate initial misalignment during installation.
