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.

The pilot (spigot) on the back of the housing locates in a bore in your frame. Check the pilot diameter H3 in the Model Details against that bore, and set out the four bolt holes on the bolt circle diameter J (J1 is the spacing between adjacent holes).

Choosing the right option

Match the housing to the insert bearing and the shaft. For example FC211 takes UC211 on a 55mm 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 UC211-32).

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