FY20FM SKF Square 4 Bolt Flange Unit with Eccentric Locking Collar 20mm

Support a 20 mm shaft with the SKF FY20FM, which combines a cast iron square flange housing with an insert ball bearing. The four-bolt flange mounts directly to a machine wall or frame on conveyors, material handling equipment and general machinery.

An eccentric locking collar secures the bearing to the shaft and is intended primarily for rotation in one direction. Standard contact seals on both sides help retain grease and protect against contamination. A grease fitting allows relubrication during maintenance.

The square housing measures 86 × 86 mm, with mounting holes on 63.5 mm centres and an overall unit width of 43 mm. The bearing can accommodate moderate initial misalignment during installation.
