What does UCP202NPMZ2 mean?

UCP202NPMZ2 is an AMI metric nickel-protected cast iron pillow block unit with a wide inner ring insert and set screw locking, for a 15 mm shaft. The part number breaks down into 6 segments:

UC: Wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC202MZ2

P: Housing style: nickel-protected cast iron pillow block. Housing part number is P203NP

2: 200 series (normal duty)

02: Bore code: 02 = 15 mm

NP: Nickel-protected housing for corrosion resistance

MZ2: Zinc-protected insert bearing for corrosion resistance

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.

Note: Part of AMI's Select corrosion-resistant series.

Frequently asked questions

What does UCP202NPMZ2 mean?

UCP202NPMZ2 is an AMI metric nickel-protected cast iron pillow block unit with a wide inner ring insert and set screw locking, for a 15 mm shaft. UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is UC202MZ2, P = housing style: nickel-protected cast iron pillow block. Housing part number is P203NP, 2 = 200 series (normal duty), 02 = bore code: 02 = 15 mm, NP = nickel-protected housing for corrosion resistance, MZ2 = zinc-protected insert bearing for corrosion resistance.

What is the bore size of UCP202NPMZ2?

The bore of UCP202NPMZ2 is 15 mm.

The housing of pillow block bearing, crafted from iron, is engineered to withstand heavy-load and high-vibration conditions with the structural rigidity and dimensional stability needed to keep the overall mounted bearing assembly performing reliably over the long term.

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 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 choose Iron for the bearing housing?

Because this pillow block bearing is specifically designed for heavy-load and high-vibration conditions, cast iron delivers superior rigidity and dimensional stability where lighter or polymer housings are prone to deformation under load, making it a purpose-built choice for this application rather than a generic substitute.

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 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.
