The UC insert
The UC series is the core of the insert family: ball bearing inserts with a spherical outer ring, made to seat in a housing and lock onto the shaft. The company names UC200 and UC300 as the common models in the range, and those two code groups carry most of the family's orders.
Code groups and sizes
UC codes run in a numbered span — the company's own catalogue prints dimension tables across the UC212 to UC318 part of the range — and each code step is a bore step. Ordering is by the code on the old insert; the code and the bore are the same statement.
| Point | Note |
|---|---|
| Common groups | UC200 and UC300 |
| Printed table span | UC212 to UC318 in the company catalogue |
| Ordered by | UC code, which carries the bore |
| Housings | Not part of this catalogue |
Set-screw locking and the shaft
UC inserts are recognised by their extended inner ring and its locking screws. If the old insert locks differently — an eccentric collar, for instance — say so in the inquiry, because the code match assumes the UC locking form.
UC or UCF?
The UCF line is the flanged form of the family. A buyer holding a bare housing takes the UC insert; a buyer replacing a complete flanged unit is in UCF territory. The family page and the blog comparison both work through the choice.
