What does UCLP212-36 mean?

UCLP212-36 is an AMI inch cast iron low base pillow block unit with a wide inner ring insert and set screw locking, for a 2 1/4" (57.15 mm) shaft. The part number breaks down into 4 segments:

UC: Wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC212-36

LP: Housing style: cast iron low base pillow block. Housing part number is LP212T

212: Frame size 212, 200 series (normal duty)

-36: Bore in sixteenths of an inch: 36/16" = 2 1/4" (57.15 mm)

Note: For inch mounted bearings, the number after the dash is the bore in sixteenths of an inch. For example, -8 is 1/2", -12 is 3/4" and -16 is 1".

Frequently asked questions

What does UCLP212-36 mean?

UCLP212-36 is an AMI inch cast iron low base pillow block unit with a wide inner ring insert and set screw locking, for a 2 1/4" (57.15 mm) shaft. UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC212-36, LP = housing style: cast iron low base pillow block. Housing part number is LP212T, 212 = frame size 212, 200 series (normal duty), -36 = bore in sixteenths of an inch: 36/16" = 2 1/4" (57.15 mm).

What is the bore size of UCLP212-36?

The bore of UCLP212-36 is 2 1/4" (57.15 mm).

The housing of pillow block bearing, crafted from iron, is engineered to withstand heavy-load and high-vibration conditions with the structural rigidity and dimensional stability needed to keep the overall mounted bearing assembly performing reliably over the long term.

Shaft retention is achieved through set screw locking in this pillow block bearing unit, which secures the shaft reliably against moderate loads and low-to-medium vibration — provided the shaft is of standard ground finish and the screws are correctly torqued — without damaging the shaft surface.

Two 0.625 inch bolts fasten the mounted bearing unit to the mounting surface, providing a secure and stable foundation that suits both new installations and direct replacement applications. This size indicates a medium-to-heavy duty housing, capable of handling higher radial loads and moderate shock, commonly found in agricultural and industrial drive applications.

Why choose Iron for the bearing housing?

Because this pillow block bearing is specifically designed for heavy-load and high-vibration conditions, cast iron delivers superior rigidity and dimensional stability where lighter or polymer housings are prone to deformation under load, making it a purpose-built choice for this application rather than a generic substitute.

Why does this bearing use Set Screw Locking to secure the shaft?

Set screw locking works by tightening one or two hardened screws directly against the shaft surface, which makes it well suited to applications where shaft positioning is fixed and loads are moderate. Its main advantage over other shaft locking methods is simplicity and low cost, which matters most when quick installation and minimal tooling are the priority.

How does the 0.625 inch affect installation and compatibility?

The bolt size directly determines whether the pillow block bearing can be mounted onto an existing frame or structure without modification. A 0.625 inch bolt corresponds to a medium-to-heavy duty hole pattern frequently found in agricultural machinery and industrial drive systems, so when replacing an existing unit, confirming this dimension ensures a drop-in fit. Mismatched bolt sizes may require redrilling the mounting surface or sourcing an adapter plate, adding time and cost to the installation.
