About Ball and Roller Bearings

One-Way Locking Needle-Roller Bearing Clutches
Single Row
Triple Row
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 bearings do not support loads from any direction. To support radial loads, use with our Needle-Roller Bearings.
Triple-row bearings support radial loads.
Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.

One-Way Locking Ball Bearing Clutches
Shielded
Sealed
Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction. Use them in applications where precision movement is required, such as pick-and-place and automated indexing conveyor systems. Shields keep out dust and contaminants.
Shielded bearings dissipate heat better than sealed bearings, but don’t keep out as much dust.
For dirty or dusty environments, sealed bearings are the best choice, since they block out contaminants better than shielded bearings.
