Key specifications

Selecting the right option

This page is for the single model UC204L2, with a 20 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 marks UC201 to UC205 as the double seal type (L2) and gives no separate allowable rotating speed for the L2 type.

Fitting and use

Check the load against the catalogue figures in the Model Details before ordering, and apply a suitable safety factor.

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.
