What this part is:

NTN UCP201-008D1 is a two-bolt cast iron pillow block mounted ball bearing unit for a 1/2 in shaft. A UC-type wide-inner-ring insert with a spherical outer race sits self-aligning in a one-piece cast iron housing and locks to the shaft with setscrews in the extended inner ring. The unit is built from bearing UC201-008D1 in housing P203D1. Complete unit: housing with insert, seals, setscrews and grease fitting. Unit Quantity: 1 Pc.

Decoding the designation:

UC — wide inner ring insert, spherical outer race, setscrew locking.

P — pillow block housing, mounted on a surface parallel to the shaft.

201 — light-duty 200-series envelope.

008 — bore in sixteenths of an inch: 8/16 = 1/2 in.

D1 — relubricatable with grease fitting.
