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.

With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings.

The addition of iron and aluminum gives these aluminum-bronze bearings high strength and excellent corrosion resistance—making them suitable for use in marine and mining applications.

A ceramic coating makes high speeds as well as rapid acceleration and deceleration possible.

Slide up to two linear ball or sleeve bearings into these housings and secure them with the included internal retaining rings.

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

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

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.

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears. The strength of this material increases with heat treating.

The head prevents these bushings from being pushed through the jig when drilling pressure is extreme. The head sits above the jig plate or can be mounted flush by installing in a counterbored hole.
