What does KHPR202 mean?

KHPR202 is an AMI metric pressed steel pillow block unit with a narrow inner ring insert and eccentric collar locking, for a 15 mm shaft. The part number breaks down into 4 segments:

KH: Narrow inner ring ball bearing insert, eccentric collar locking, spherical outer ring. Insert part number is KH202

PR: Housing style: pressed steel pillow block. Housing part number is PP4

2: 200 series (normal duty)

02: Bore code: 02 = 15 mm

Note: For metric mounted bearings, the bore is usually the bore code × 5 mm. Codes 00, 01, 02 and 03 are the exceptions: 10, 12, 15 and 17 mm.

Frequently asked questions

What does KHPR202 mean?

KHPR202 is an AMI metric pressed steel pillow block unit with a narrow inner ring insert and eccentric collar locking, for a 15 mm shaft. KH = narrow inner ring ball bearing insert, eccentric collar locking, spherical outer ring. Insert part number is KH202, PR = housing style: pressed steel pillow block. Housing part number is PP4, 2 = 200 series (normal duty), 02 = bore code: 02 = 15 mm.

What is the bore size of KHPR202?

The bore of KHPR202 is 15 mm.

Shaft retention is achieved through eccentric collar locking in this pillow block bearing unit, which secures the shaft reliably against moderate loads and intermittent vibration — provided the collar is rotated firmly in the direction of shaft rotation and the locking screw is fully tightened — without damaging the shaft surface.

Two M10 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. M10 represents a mid-range metric fastener, widely used across standard industrial pillow blocks where moderate radial loads and everyday operating conditions are the norm.

Why does this bearing use Eccentric Collar Locking to secure the shaft?

Eccentric collar locking works by rotating an offset collar in the direction of shaft rotation until it clamps firmly around the shaft, which makes it well suited to applications where the shaft surface must remain undamaged and load distribution needs to be more even. Its main advantage over other shaft locking methods is a broader contact area that reduces shaft stress, which matters most when the application involves intermittent loads, frequent starts and stops, or softer shaft materials.

How does the M10 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. An M10 bolt corresponds to a mid-range hole pattern widely used in standard metric pillow blocks across a broad range of industrial 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.
