Bearings with eccentric lock have a collar that you twist in one direction to grip and the other to release. Compared to bearings with a set screw, they’re easier to install, require less adjustment over time, and are better for high-speed applications. But, they only work on shafts that spin in one direction.

High-Temperature Linear Ball Bearings

Bearing with Retaining Ring Grooves

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).

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).

High-Load Mounted Linear Ball Bearings

Designed to handle heavy loads, these bearings have the highest load capacities of any mounted linear ball bearings we offer. They are for use with round end-supported shafts. End seals keep lubricant in and dirt out.

Use fixed-alignment bearings where shaft misalignment is unlikely.

Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

High-Load High-Speed Mounted Linear Sleeve Bearings for Support Rail Shafts

With two bearings mounted in a single housing, these bearings have higher load capacities than standard ones. A ceramic liner helps them achieve high speeds as well as rapid acceleration and deceleration. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. Made of ceramic-coated aluminum, their housing is lightweight and corrosion resistant. These bearings are for fixed alignment, ideal for well-aligned shafts. Note: Not for use with ceramic-coated aluminum or 300 series stainless steel shafts.

Metric Fast-Travel Ultra-Precision Lead Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread type, thread size, thread pitch, and number of thread starts.

Alloy steel lead screws are hard and strong.

Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric Precision Ball Screws and Nuts

Precision cut threads make these metric ball screws approximately four times more accurate than standard ball screws. Use them when exact positioning is essential. They come with finished ends and the nut already on, so they’re ready to use right away. The ball nuts have a flange design that makes it easy to mount objects on them. Inside, they have ball bearings to produce smooth, low-friction travel for applications that require high-speed and repeatable movement.

Root diameter indicates the diameter the ball screw will be after machining away the threads.
