Pillow Block Bearing 3/4 in Bore

The NTN UCP-3/4M is a pillow block bearing with a 3/4 in cylindrical bore and cast iron housing. It suits machinery requiring a bolt-through mounted radial ball bearing insert made from alloy steel.

Installation and Common Issues

The unit mounts via two bolt-through holes on a 3 49/64 in center-to-center length. A base height of .563 in and base width of 1.5 in set the mounting footprint. Double seals protect the NLGI #3 equivalent lubricant from contamination during fitting.

Sustained Load Behaviour

Rated for a maximum speed of 6,700 RPM, the bearing operates continuously between -40 and 250 degrees F. The centre height of 1 19/64 in aligns the shaft centreline for stable rotation under prolonged radial loads.

Questions about this item

How can I verify the pillow block bearing is rotating correctly after installation?

Spin the shaft by hand; it should turn smoothly without binding, and during operation the bearing must stay below 250 °F while running at or under 6,700 RPM.

What components are included with the UCP-3/4M and what must be sourced separately?

The unit comes with the cast-iron housing, double-sealed radial ball insert pre-lubricated with NLGI #3 equivalent grease, and two bolt-through mounting holes; mounting bolts, washers, and shaft are not supplied.

Which bore size should I select for a 3/4 inch shaft?

Choose the 3/4 in bore version — it matches a 3/4 in cylindrical shaft and provides a base height of 0.563 in with a center height of 1 19/64 in.
