BUS200 Series Cam Clutch is a general purpose Cam Clutch used in backstop, overrunning, and indexing applications. Generally the customer supplies the inner race as a component of his machinery but if desired, Tsubaki can also provide an inner race. A second very convenient feature is that the BUS200 Series outside diameter matches with 6200 Series ball bearings. Because of the common popular dimensions, BUS200 Series Cam Clutches are found as integral components in many pieces of machinery; these include backstops within gear boxes and as components within timing gear applications. BUS200 Series ships pre-lubricated with grease. Oil lubrication is generally recommended for indexing applications.
