The CSK series is a one-way (clutch) bearing.One way Bearing Sprag/Clutch Freewheel and also called as Backstops. The one-way bearings are used in any application that requires one direction rotation, such as mining, hydraulic, textile, printing and washing machines, conveyor systems that carry products to a higher level should not be reversed because of gravity during any power shortage.

This is the cheapest back-stopping sprag clutch I could locate but quality is not lost with affordability. For my low-speed applications it works wonderfully. At low speeds there is near zero back-spin. Higher speeds have a minute amount before fully engaging sprags. The dust seal is quite good but did start to come out once when I drop the bearing on the workbench.
