SBI Series In-line Mounting Ball Bearing Supported clutches are comprised of an HPI clutch with an extended shaft (inner race) for in-line mounting. The extended shaft provides a convenient way to mount a coupling to accommodate the misalignment in the in-line application. This design is intended for applications with medium to heavy-duty indexing requirements. They are oil lubricated and equipped with lip type seals. Grease is available. Increased overrunning speeds are possible with clutches having steel labyrinth grease seals.
