The combination of an AGF series roller ramp clutch with F3 and F2/F4 flanges provide a unit complete with support bearing and its own integral lubrication system. The units are primarily intended for backstop applications, but can also be used as reciprocating arm on indexing applications.

When used as a backstop, outer race rotation is prevented by cam bolt, which by its shape compensates for misalignment. The bolt must be radially free in its location to avoid loading the bearings, so preferred location is with a slot of width 0.5mm above bolt dia. "C".
Higher torque clutches for 25-35mm shafts can be supplied to special order.
