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.

Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.

Thread these one-piece collars onto an Acme lead screw to separate and position components, or use them as an end stop to limit travel. Tighten the clamping screw to secure.

To ensure compatibility, please select a collar that has the same thread type, direction, and size as your lead screw.

Black-oxide carbon steel collars have mild corrosion resistance. 303 stainless steel collars have good corrosion resistance.
