What does BLLP5-14 mean?

BLLP5-14 is an AMI inch cast iron pillow block unit with a narrow inner ring insert and set screw locking, for a 7/8" (22.22 mm) shaft. The part number breaks down into 4 segments:

B: Narrow inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is B5-14

LLP: Housing style: cast iron pillow block. Housing part number is LLP5

5: 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".

Frequently asked questions

What does BLLP5-14 mean?

BLLP5-14 is an AMI inch cast iron pillow block unit with a narrow inner ring insert and set screw locking, for a 7/8" (22.22 mm) shaft. B = narrow inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is B5-14, LLP = housing style: cast iron pillow block. Housing part number is LLP5, 5 = 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 BLLP5-14?

The bore of BLLP5-14 is 7/8" (22.22 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 0.375 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 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.
