Note: mounted bearing units follow ISO 9628, so the model numbers match ours and the dimensions are interchangeable. FYH / NSK / NTN / KOYO UKP series need an H adapter sleeve (e.g. UKP205+H2305). SKF has no tapered-bore adapter-sleeve equivalent.

Common questions
- What does the number in a model such as UCP205 mean?
- The last two digits are the bore size code: 204 = 20 mm, 205 = 25 mm, 206 = 30 mm, and so on up to 213 = 65 mm. The code is shared across the series, so UCF205, UCT205 and UCPA205 all take a 25 mm shaft even though the housings differ.
- What if your model is not listed in the table?
- This table only covers items for which we have confirmed equivalent models. Please send us the model number and quantity, and we will check availability and match an equivalent from our factory catalogue.
