Key specifications

Selecting the right option

This page is for the single model UC210L3, with a 50 mm bore. If you need another shaft size, the related pages below list the other sizes in this range.

Metric bores are in mm: match the bore to the shaft you have.

For the standard seal version of this size, see the UC200 series pages below. The catalogue lists a lower allowable rotating speed for the L3 triple-lip type than for the standard seal.

Fitting and use

Check the load and speed against the catalogue figures in the Model Details before ordering, and apply a suitable safety factor. The allowable rotating speed in the catalogue is a standard value: it falls to 80% for units fitted with covers, and a loose fit between shaft and inner ring reduces it further.

Tighten the set screws once the insert is in position on the shaft.

Match the insert to a housing with the same size number: the spherical O.D. seats in a matching spherical housing bore.

If you are unsure which insert suits a shaft and housing, send AIMS the part numbers or sizes and we will confirm the fit.
