What does MUCPPL205-14W mean?

MUCPPL205-14W is an AMI inch PBT thermoplastic 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 6 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

PPL: Housing style: PBT thermoplastic pillow block. Housing part number is PPL205

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

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

W: Housing color: white

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 corrosion-resistant series.

Frequently asked questions

What does MUCPPL205-14W mean?

MUCPPL205-14W is an AMI inch PBT thermoplastic 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, PPL = housing style: PBT thermoplastic pillow block. Housing part number is PPL205, 205 = frame size 205, 200 series (normal duty), -14 = bore in sixteenths of an inch: 14/16" = 7/8" (22.22 mm), W = housing color: white.

What is the bore size of MUCPPL205-14W?

The bore of MUCPPL205-14W is 7/8" (22.22 mm).

The housing of pillow block bearing, crafted from plastic, is engineered to withstand moisture-rich and chemically aggressive conditions with the lightweight corrosion resistance and rust-free durability 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 Plastic for the bearing housing?

Because this pillow block bearing is specifically designed for moist, corrosive, or chemically aggressive conditions, plastic delivers lightweight corrosion resistance and zero rust where standard metal housings are prone to oxidation and surface degradation, 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.
