Support shafts, bearings, and other moving parts that are routed through a hole. These grommets are slippery to allow parts to move freely in the hole. Install them on thin sheet-metal panels.

Vibration-Damping Bushings

Easier to install than grommets, push these bushings through your mounting hole to dampen vibration. Use them with a vibration-damping washer to isolate vibration.

Extreme-Temperature Vibration-Damping Bushings

In addition to having a wider temperature range than our other vibration-damping bushings, these have excellent weather resistance.

Ribbed Vibration-Damping Bushings

Ribbed bushings are more flexible than our smooth vibration-damping bushings, so they're easier to install.

Lead Screw Collars

Two-Piece Clamping Acme Lead Screw Collars

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

Clamping Acme Lead Screw Collars

Thread these one-piece collars onto an Acme lead screw.

Metric Clamping Lead Screw Collars

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Idler Rotary Shafts

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.

Thread-Mount Idler Rotary Shafts

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications. They have a retaining-ring groove, retaining ring, and spacers to position your component and hold it in place.

Dissolvable Shims

Use these paper shims to create a gap while welding, then spray them with water and they instantly melt away.
