Tritan UCFL207-21 collectible

Industrial flange bearing

The Tritan UCFL207-21 is a two-bolt flange bearing designed for power-transmission equipment. Its cast-iron rhombus housing holds an alloy-steel radial ball insert with a 1-5/16 inch cylindrical bore. The unit arrives double sealed and pre-lubricated with NLGI #2 equivalent grease. Maintenance teams and OEM builders use it to support rotating shafts in conveyors, fans and general machinery.

Sustained load behaviour

The fixed-expansion design keeps the bearing centred under continuous radial loads. Double seals retain lubricant and exclude contaminants during extended runs. Operating limits span -40 to 250 degrees Fahrenheit, so the insert maintains film strength in cold starts and high-temperature environments. Single-row construction provides consistent torque without the heat buildup seen in multi-row alternatives.

Mounting interface limits

Two bolt holes set the mounting pattern, so the structure must provide matching centres and a flat surface for the 1 3/4 inch overall height. The 6 11/32 inch length and 3 35/64 inch width define the footprint that the frame must accommodate. Shaft diameter must match the 1-5/16 inch bore exactly; no adapter sleeves are included. Installers must verify bolt spacing and shaft tolerance before assembly.
