Miniature One-Way Clutch Bearings,
One-Way Needle-Roller Bearing Clutches, METRIC Sizes


CLI one-way bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed.Also known as drawn-cup roller clutches. An arrow on the lip indicates the rotational direction that locks the bearings.Single-row bearings do not support loads from any direction. To support radial loads, use with our Needle-Roller Bearings.Triple-row bearings support radial loads.

CLI miniature one-way clutch consists of drawn cup, rollers, cage, and springs.The drawn cup, made of carburized steel sheet, has a unique structure: a protruding portion, which serves as a stopper of rotation on the outside surface at O.D. side, and a cam on the outer ring at bore side are provided.
