Ultra-Thin Linear Sleeve Bearings
![](/prerenderstable/mvPRE/contents/gfx/imagecache/795/7954n18_43ff7948-adc5-40f0-8b46-b7b9c96971d2@halfx_638043098827863949.png?ver=imagenotfound)
Thinner than standard linear sleeve bearings, these bearings fit where clearance is a concern. Pair them with round end-supported shafts. They have fixed alignment, so they’re best for applications where shaft misalignment is unlikely. The PTFE lining stands up to chemicals and won’t scratch the shaft. To install, slide them into a housing (not included).

Linear Bearings for Ball Splines

Combine these bearings with a ball spline to create a compact linear and rotary motion system for applications with fast, complex movements, such as robotics. These bearings move smoothly and precisely even at high speeds along ball splines while grooves on the ball spline transmit rotary power. Clip a retaining ring into the groove on these bearings to position them in your system. Use the keyway and included machine key for attaching your load.
Stainless steel bearings are more corrosion resistant than steel bearings.
Splines are alloy steel for high strength and wear resistance. They're hardened only on the outside, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Those with a step-down end have a shoulder near the end to stop gears, sprockets, and bearings.

High-Load Mounted Linear Sleeve Bearings
![](/prerenderstable/mvPRE/contents/gfx/imagecache/654/6542n12-1613671463-p9@halfx_637492466922223467.png?ver=imagenotfound)
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.

Threadless Lead Screw Nuts

Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins. Nuts move towards you when the shaft rotates clockwise and away from you when the shaft rotates counterclockwise. To prevent overload damage, these nuts can be adjusted to slip and stop travelling at a given thrust load. Thrust loads are loads that are applied parallel to the shaft. Bearings are permanently lubricated to save maintenance time and effort.
Travel distance per turn is the distance the nut moves with one revolution of the shaft.

Ball Screw/Splines and Bearings
![](/prerenderstable/mvPRE/contents/gfx/imagecache/404/4049n13-pr@halfx_1683738492.png?ver=imagenotfound)
From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.
The ball bearings move smoothly and precisely, even at high speeds. They're powered independently, so you can drive one bearing at a time or both together to coordinate movements.
The ball screw/splines are hardened on the surface, so they stand up to repeated motion. They’re also hollow, so you can run electrical wiring, compressed air tubing, coolants, or lubricant through their center.
