Key specifications

Fitting and use

The housing is supplied without an insert bearing. Order the insert separately and lock it to the shaft in the way its own type requires: a UC insert locks to the shaft with two set screws.

Mount the flange against a flat, rigid face and use the bolt size and bolt hole spacing J shown for the size. J is the bolt hole spacing and N the bolt hole diameter.

Choosing the right option

Match the housing to the insert bearing and the shaft. For example FB207 takes UC207 on a 35mm shaft.

Choose the metric size for a metric shaft; for an inch shaft pick the same housing and order the insert with the matching dash number (for example UC207-20).

The Bolt Size option is the mounting bolt for the housing unit tables (inch equivalent in the Model Details).
