Ball Bearings

These steel ball bearings handle higher loads than stainless steel and plastic bearings.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

Thrust Ball Bearings

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components.

Corrosion-Resistant Thrust Ball Bearings

A combination of stainless steel and nylon components provide increased corrosion resistance over standard thrust ball bearings.

Light Duty Dry-Running Thrust Bearings

Use where high loads and speeds are not required.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.

Ball Joint Rod End Seals

Keep dirt out and lubrication in to extend the life of your rod ends.

Lightweight Swivel Joints

These nylon swivel joints are 80% lighter than steel swivel joints with better corrosion resistance.

Clamping Acme Lead Screw Collars

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

Self-Centering Screw-Clamp Bushings

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket.

932 Bearing Bronze Tubes

Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Round Shims

Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Ring Shim Sets

Be prepared with ring shims in a variety of thicknesses. These shims fit around fasteners and shafts to precisely align, level, and adjust spacing.

Wide-Rim Ring Shims

Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts.

Peel-Away Layered Ring Shims

These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need.

Color-Coded Ring Shims

Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims, which are color-coded by thickness for easy identification.

Color-Coded Ring Shim Sets

Be prepared with ring shims in a variety of thicknesses. These shims are color-coded by thickness for easy identification.

Shim Sets for Keyed Shafts

Be prepared with shims in a variety of thicknesses. Also known as arbor spacers, these shims are notched to fit over keyed shafts.

Shims for Keyed Shafts

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.
