About Linear Bearings

Electrically Insulated Ball Bearings

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing.

Linear Bearings

Linear Sleeve Bearings

Because they usually do not require lubrication, linear sleeve bearings outperform linear ball bearings in dirty environments.

High-Speed Linear Sleeve Bearings

A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible.

High-Speed Ultra-Thin Linear Sleeve Bearings

Use these ultra-thin sleeve bearings in high-speed applications where clearance is a concern.

Linear Sleeve Bearings for Support Rail Shafts

Sleeve bearings outperform ball bearings in dirty environments. Use them for low speed applications.

High-Speed Linear Sleeve
Bearings for Support Rail Shafts

These bearings have a ceramic liner to help them achieve high speeds as well as rapid acceleration and deceleration.

Mounted Linear Bearings

High-Speed Flange-Mounted Linear Sleeve Bearings

A ceramic coating makes high speeds as well as rapid acceleration and deceleration possible.

Mounted Linear Sleeve Bearings

Virtually maintenance free, these bearings have slippery, chemical-resistant liners that don't require added lubrication.

High-Speed Mounted Linear Sleeve Bearings

A ceramic coating makes high speeds as well as rapid acceleration and deceleration possible.

High-Load Mounted Linear Sleeve Bearings

With two bearings mounted in one housing, these sleeve bearings can handle heavier loads than standard mounted linear sleeve bearings.

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.

A ceramic coating makes high speeds as well as rapid acceleration and deceleration possible.

High-Load Mounted Linear Sleeve
Bearings for Support Rail Shafts

With two bearings mounted in one housing, these sleeve bearings withstand heavy loads. Use them on round support rail shafts for applications that require maximum rigidity.

Ultra-High-Temperature Ceramic

Fracture- and Thermally Shock-Resistant
Silicon-Nitride Ceramic Balls

Often used to create bearings, silicon-nitride ceramic is harder than many types of bearing steel but is lightweight and can be easily polished. It also withstands high temperatures.

High-Strength Fracture- and
Wear-Resistant Zirconia Ceramic Balls

Often used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed.

Nonporous Alumina Ceramic Balls

Acid-Resistant Silicon-Carbide Ceramic Balls

Extremely hard with excellent corrosion resistance, this silicon-carbide ceramic is often used for rubbing parts such as bearings and bushings in chemicalprocessing environments.
