The DC series features a cage and race assembly, which results to a non-bearing supported freewheel. The bearing support is ideal for use in operations where axial and loads are needed together with lubrication and sealing. The sprag space tolerance of the model should not go beyond when any bearing clearances or mounting tolerances are considered. The taper between races must not go beyond 0.007 mm for a 25 mm width.
The external races type-A and type-B must be pressed into enclosures that will not deform after assembly. The DC series is manufactured by Stieber Clutch.
