High-Temperature Linear Ball Bearings

The choice for low-friction motion in high-temperature environments. Bearings are for use with round end-supported shafts and have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).
For technical drawings and 3-D models, click on a part number.

High-Temperature Linear Ball Bearings for Support Rail Shafts

The choice for low-friction motion in high-temperature environments. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure in place with two retaining rings (sold separately).

Corrosion-Resistant Flange-Mounted Linear Ball Bearings

The bearing, housing, and balls of these mounted bearings are stainless steel for excellent corrosion resistance. The flanged housing is good for vertical linear motion applications. All bearings are for use with round end-supported shafts and have a fixed-alignment design for use where shaft misalignment is unlikely. End seals keep lubricant in and dirt out.

Metric Ball Screws and Nuts

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread size and travel distance per turn. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
