Radial ball bearing with square flange

This Tritan UCF213-40 is a 4 bolt flange bearing designed for power transmission applications. It uses a radial ball insert made from alloy steel and is housed in a cast iron square housing. The unit is double sealed and comes pre-lubricated with NLGI #2 equivalent grease. It is suited for maintenance teams and machinery builders.

Replaces worn fixed expansion bearings

The bearing insert type UC213-40 fits directly into the cast iron housing as a fixed expansion unit. The jump is worth it when the existing bore shows wear or the seals have failed. A cylindrical bore diameter of 2 1/2 in matches the shaft without adapters. Buyers needing a floating or expansion type unit cannot use this fixed housing.

Operates between -40 and 250 degrees F

The lubricant and seal materials define the practical temperature window for continuous use. Mount hole centres sit at 5 55/64 in with an overall height and length of 7 13/32 in. The blue finish identifies the brand but does not affect the rating. Installers without the exact bolt pattern or temperature margin should verify compatibility first.

Questions about this item

What are the exact bolt-hole centre-to-centre dimensions for the square flange on this UCF213-40?

The mount holes form a square pattern with a centre-to-centre height of 5 55/64 in, and the overall flange measures 7 13/32 in both height and length.

Which step is most often missed when installing the UC213-40 insert into the cast-iron housing?

Installers frequently forget to apply NLGI #2 equivalent grease to the radial ball insert before seating it, leaving the double-sealed bearing under-lubricated from the start.

How often should the factory-sealed lubricant be refreshed when the bearing runs continuously near 250 °F?

At sustained high temperatures the NLGI #2 equivalent grease degrades faster, so plan to purge and repack the double-sealed insert every six months or after 2 000 operating hours.
