Designation explained
What UCP216 means
Standard bearing numbers encode the type, the dimension series and the bore. Anything after the base number — seals, clearance, cage — is a suffix.
| Part | Meaning |
|---|---|
UC | Insert bearing with cylindrical bore and set screws (UC2xx) |
P | Two-bolt pillow block housing (P2xx) |
2 | Light series (200) |
16 | 16 → 80 mm shaft diameter (16 × 5) |
Variants
Common UCP216 variants
Suffixes change the bearing without changing its boundary dimensions. The exact letters differ between manufacturers — always order by the full designation from the maker you choose.

UK / UKP | UKP216+H | Tapered-bore insert for adapter sleeve mounting instead of set screws |
UCFL / UCF / UCT | UCFL216 | Same insert in a two-bolt flange, four-bolt flange or take-up housing |
SS / thermoplastic | SSUCP216 | Stainless steel or plastic housing variants for food and wash-down use |

About these dimensions. Boundary dimensions follow JIS B 1559 / ISO 3228 for the shaft centre height and bolt spacing of P2xx housings, dimension series P2, and are the same for every manufacturer of a standard UCP216. Chamfers, load ratings, speed limits and weight depend on the manufacturer and design and are not shown — use the maker's datasheet for engineering decisions. Last checked 9 October 2026.

What size shaft fits a UCP216?
A UCP216 takes a 80 mm shaft. Inch versions carry a suffix in sixteenths of an inch — for example UCP216-16 for a 1″ shaft where that size exists.
What is the centre height of a UCP216?
The shaft centre sits 88.9 mm above the mounting base, with bolt holes 232 mm apart and an overall length of about 292 mm. Overall height and foot details vary slightly between manufacturers.
Can I replace only the bearing in a UCP216?
Yes — the insert is a UC216 and the housing a P216. Inserts from different makers with the same designation fit the standard housing.
Where are the load ratings?
They depend on the insert manufacturer and are not listed here. Check the datasheet for the exact unit you intend to use.
