One-Way Locking Needle-Roller Bearing Clutches

The needles in these 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 Bearing—Single-row bearings do not support loads from any direction. To support radial loads, use with our Needle-Roller Bearings.

Triple-Row Bearing—Triple-row bearings support radial loads.

301 Stainless Steel Springs—Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.
