Two-bolt flange bearing for fixed-mount shafts

The Tritan HCFLU210-31 is a cast-iron rhombus housing with a 1-15/16 inch cylindrical bore and an included HC210-31 radial ball insert made from alloy steel. It suits machinery that needs a fixed expansion type on a two-hole mounting pattern.

Sealed lubrication handles extreme temperatures

Double-sealed closures keep the NLGI #2 equivalent grease inside while contaminants stay out. The assembly operates from minus 40 degrees F up to 250 degrees F without relubrication intervals specified in the data.

Blue finish and ready-to-mount insert

The bearing insert comes pre-fitted in the housing so installation only requires bolting the unit to the frame. No separate seals, collars or lubrication tools are bundled with this part number.

Questions about this item

How do I install the 2-bolt flange bearing and what step is commonly missed?

Mount the cast-iron rhombus housing using both bolt holes, then torque the set screws on the HC210-31 insert to lock the 1 15/16 in cylindrical bore to the shaft; the step often missed is fully tightening both set screws after alignment.

What maintenance will the double-sealed radial ball bearing need later?

The NLGI #2 equivalent grease is factory-filled and the double seals retain it; no re-lubrication is required unless operating near the 250 °F maximum or -40 °F minimum temperature limits.

What is the first limit reached under sustained heavy load?

The fixed-expansion design means the housing cannot accommodate axial growth, so shaft thermal expansion beyond the 1 15/16 in bore fit will bind the single-row balls before the 250 °F temperature ceiling is hit.
