With two bearings mounted in one housing, these sleeve bearings can handle heavier loads than standard mounted linear sleeve bearings. All have an anodized aluminum housing that’s lightweight and stands up to corrosion. They also have a slippery, chemical-resistant PTFE liner, so there’s no need for added lubrication. Use these fixed-alignment bearings with round end-supported shafts where shaft misalignment is unlikely.

High-Load High-Speed Mounted Linear Sleeve Bearings

With two bearings mounted in a single housing, these bearings have load capacities more than 10 times as high as standard mounted linear sleeve bearings. A ceramic liner helps them achieve high speeds as well as rapid acceleration and deceleration. Made of anodized 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.

High-Load Mounted Linear Sleeve Bearings for Support Rail Shafts

With two bearings mounted in one housing, these sleeve bearings are designed to withstand heavy loads. Use them on round support rail shafts for applications that require maximum rigidity. All of these bearings have a ceramic-coated aluminum housing that’s lightweight and stands up to corrosion. They also have a slippery, chemical-resistant PTFE liner, so there’s no need for lubrication. These fixed-alignment bearings are for use where shaft misalignment is unlikely.

Linear Bearing Housings

For Two Bearings

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

Housings for two bearings give you better running accuracy and alignment than using two separate pillow blocks.

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.

Ball nuts with a travel distance per trun greater than 1 mm have a seal that prevents some contaminants from getting inside them. However, to make sure they don’t create torque and heat, there’s a bit of clearance between the seal and screw, so the seal can’t keep out everything.

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

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