Frequently asked questions

What does BPR6 mean?

BPR6 is an AMI metric pressed steel pillow block unit with a narrow inner ring insert and set screw locking, for a 30 mm shaft. B = narrow inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is B6, PR = housing style: pressed steel pillow block. Housing part number is PP7, 6 = frame size 206, 200 series (normal duty); metric bore 30 mm.

What is the bore size of BPR6?

The bore of BPR6 is 30 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 M12 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. One of the most prevalent sizes in metric pillow block applications, M12 balances holding strength and versatility, making it the default choice for a broad range of conveyor, drive, and general industrial installations.

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 M12 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 M12 bolt corresponds to one of the most prevalent hole patterns in metric pillow block applications, balancing strength and versatility across conveyor, drive, and general industrial installations, 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.
