What does MUCPPL206-18CB mean?

MUCPPL206-18CB is an AMI inch PBT thermoplastic pillow block unit with a stainless steel wide inner ring insert and set screw locking, for a 1 1/8" (28.58 mm) shaft. The part number breaks down into 7 segments:

M: Stainless steel insert bearing

UC: Wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is MUC206-18

PPL: Housing style: PBT thermoplastic pillow block. Housing part number is PPL206

206: Frame size 206, 200 series (normal duty)

-18: Bore in sixteenths of an inch: 18/16" = 1 1/8" (28.58 mm)

C: Cover configuration: two open covers, for positions where the shaft runs through the bearing

B: Housing color: black

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 Shur Seal corrosion-resistant series.

Frequently asked questions

What does MUCPPL206-18CB mean?

MUCPPL206-18CB is an AMI inch PBT thermoplastic pillow block unit with a stainless steel wide inner ring insert and set screw locking, for a 1 1/8" (28.58 mm) shaft. M = stainless steel insert bearing, UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is MUC206-18, PPL = housing style: PBT thermoplastic pillow block. Housing part number is PPL206, 206 = frame size 206, 200 series (normal duty), -18 = bore in sixteenths of an inch: 18/16" = 1 1/8" (28.58 mm), C = cover configuration: two open covers, for positions where the shaft runs through the bearing, B = housing color: black.

What is the bore size of MUCPPL206-18CB?

The bore of MUCPPL206-18CB is 1 1/8" (28.58 mm).

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 0.5 inch bolts fasten the the mounted bearing unit to the mounting surface, providing a secure and stable foundation that suits both new installations and direct replacement applications. A mid-range fastener size suited to standard industrial pillow blocks handling moderate radial loads in general machinery and conveyor applications.

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 0.5 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 0.5 inch bolt corresponds to a standard mid-range hole pattern common across general industrial and conveyor applications, 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.
