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; a UK insert is a tapered bore insert that mounts on the shaft with an adapter sleeve.
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 F314 takes UC314 on a 70mm 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 UC314-44). Sizes without an inch bore in the unit tables: F306, F307, F310, F316, F317, F322, F324, F326, F328.
The Bolt Size option is the mounting bolt for the housing unit tables (inch equivalent in the Model Details).
