Tritan UCP201-8 47MM Pillow Block Bearing collectible

Industrial Pillow Block Bearing

The Tritan UCP201-8 is a cast-iron pillow block bearing with a 47 mm bore diameter and set-screw locking. It uses a double-sealed radial ball insert made from alloy steel and comes pre-lubricated with grease for maintenance-free operation. This unit suits conveyor, fan and light-machinery applications where a fixed, bolt-through mount is required.

Verify Shaft And Mounting Before Order

Confirm the shaft diameter is exactly 1/2 inch cylindrical to match the bore. Check that the mounting surface can accommodate a 3 47/64 inch center-to-center bolt pattern in both length and width. Ensure the operating environment stays within -40 to 250 degrees F and that a fixed, non-expansion housing is correct for the shaft arrangement.

Replaces Worn Or Split-Housing Units

This bearing replaces damaged cast-iron pillow blocks of the same bore and bolt pattern without frame modification. The upgrade is worth it when the original housing is cracked, the seals have failed or the set-screw locking has loosened beyond adjustment. It is not for applications needing an expansion-type bearing, a different bore size or a stainless-steel housing.
