What does MUCP205-14 mean?

MUCP205-14 is an AMI inch 304 cast stainless steel pillow block unit with a stainless steel wide inner ring insert and set screw locking, for a 7/8" (22.22 mm) shaft. The part number breaks down into 5 segments:

M: Stainless steel insert bearing

UC: Wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is MUC205-14

P: Housing style: 304 cast stainless steel pillow block. Housing part number is MP205

205: Frame size 205, 200 series (normal duty)

-14: Bore in sixteenths of an inch: 14/16" = 7/8" (22.22 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".

Note: Part of AMI's Prime Plus corrosion-resistant series.

Frequently asked questions

What does MUCP205-14 mean?

MUCP205-14 is an AMI inch 304 cast stainless steel pillow block unit with a stainless steel wide inner ring insert and set screw locking, for a 7/8" (22.22 mm) shaft. M = stainless steel insert bearing, UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is MUC205-14, P = housing style: 304 cast stainless steel pillow block. Housing part number is MP205, 205 = frame size 205, 200 series (normal duty), -14 = bore in sixteenths of an inch: 14/16" = 7/8" (22.22 mm).

What is the bore size of MUCP205-14?

The bore of MUCP205-14 is 7/8" (22.22 mm).

The housing of pillow block bearing, crafted from stainless steel, is engineered to withstand washdown, food-grade, and marine conditions with the high corrosion resistance and hygienic structural strength 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 0.375 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 is among the most common in light-to-medium duty inch-series pillow blocks, offering a practical balance between holding strength and compact housing dimensions.

Why choose Stainless Steel for the bearing housing?

Because this pillow block bearing is specifically designed for washdown, food-grade, or marine conditions, stainless steel delivers high corrosion resistance combined with structural strength where standard carbon steel or cast iron housings are prone to rust and contamination risk, 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 0.375 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 0.375 inch bolt corresponds to one of the most widely used hole patterns in light-to-medium duty inch-series pillow blocks, 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.
