What does UCP206CE mean?

UCP206CE is an AMI metric cast iron pillow block unit with a wide inner ring insert and set screw locking, for a 30 mm shaft. The part number breaks down into 5 segments:

UC: Wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC206

P: Housing style: cast iron pillow block. Housing part number is P206N

2: 200 series (normal duty)

06: Bore code: 06 × 5 = 30 mm

CE: Cover configuration: one open cover (the shaft passes through) and one closed end cover, for mounting at the end of a shaft

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 UCP206CE mean?

UCP206CE is an AMI metric cast iron pillow block unit with a wide inner ring insert and set screw locking, for a 30 mm shaft. UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC206, P = housing style: cast iron pillow block. Housing part number is P206N, 2 = 200 series (normal duty), 06 = bore code: 06 × 5 = 30 mm, CE = cover configuration: one open cover (the shaft passes through) and one closed end cover, for mounting at the end of a shaft.

What is the bore size of UCP206CE?

The bore of UCP206CE 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 M14 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. A less common transitional size between M12 and M16, used where the standard M12 falls marginally short of the required clamping force without necessitating the larger footprint of an M16 housing.

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 M14 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 M14 bolt corresponds to a transitional hole pattern between M12 and M16, used where standard M12 falls marginally short of the required clamping force, 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.
