About Linear Bearings

Bearings are for use with round end-supported shafts. All have end seals to keep lubricant in and dirt out.

Fixed-alignment bearings are for use where shaft misalignment is unlikely.

High-Load Mounted Linear Ball Bearings for Support Rail Shafts

Designed to handle heavy loads, these bearings have higher load capacities than comparable standard mounted linear ball bearings for support rails. Use them for applications that require maximum rigidity. All are self-aligning to compensate for shaft misalignment and have end seals to keep lubricant in and dirt out.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. They also have internal chamfers, so it's easier to insert bits, pins, and punches into the bushing. Don't see the size you need? Additional sizes are available.
