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 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.

Ball Joint Rod End Inserts
Without changing the ID, these inserts handle some misalignment on rod ends. They attach to your rod end to move your fastener away from the rod-end body.
Cone-style inserts help position rod ends between receiving forks, straps, and clevises.

Clamping Acme Lead Screw Collars
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, size, and number of thread starts as your lead screw.
Black-oxide carbon steel collars have mild corrosion resistance. 303 stainless steel collars have good corrosion resistance.

Two-Piece Clamping Acme Lead Screw Collars
Mount these two-piece collars anywhere on an Acme lead screw without removing components. Use them to separate and position components or 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, size, and number of thread starts as your lead screw.
Black-oxide carbon steel collars have mild corrosion resistance.
Flanged Screw-Clamp Bushings
A mounting flange prevents movement during tightening. These bushings are good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

Corrosion-Resistant Flanged Screw-Clamp Bushings
Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.
Stainless steel bushings have excellent corrosion resistance and can withstand prolonged exposure to moisture.
