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; an NC insert locks with a concentric collar; a UK insert is a tapered bore insert that mounts on the shaft with an adapter sleeve; an SB insert locks to the shaft with set screws; an SA insert locks with an eccentric collar.

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 F210 takes UC210 on a 50mm 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 UC210-30).

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