    Electrically Insulating Ball Bearings

    Protect bearings from stray currents. The ceramic balls insulate bearings from electrical charges in electric motors and power generators that can damage the inner ring over time. The balls also generate less heat than metal ones, so you don’t have to lubricate them as often to keep bearings running smoothly.
    Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.
    Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.
    ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.

    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

    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-Speed Flange-Mounted Linear Sleeve Bearings

    A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. The flange-mount design is good for vertical linear motion applications. Bearings are for use with round end-supported shafts and are self-aligning to compensate for shaft misalignment. End seals keep contaminants out.

    High-Speed Mounted Linear Sleeve Bearings for Support Rail Shafts

    A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. End seals keep contaminants out. These bearings are self-aligning to compensate for shaft misalignment. Note: Not for use with ceramic-coated aluminum or 300 series stainless steel shafts.

    High-Speed Ultra-Thin Linear Sleeve Bearings

    Use these ultra-thin sleeve bearings in high-speed applications where clearance is a concern. They have a ceramic liner to achieve high speeds and allow rapid acceleration and deceleration. Pair them with round end-supported shafts. These fixed-alignment bearings are for use where shaft misalignment is unlikely. To install, slide them into a housing (not included).
