    Thin-Profile Crossed-Roller Bearings

    Image of Product. Front orientation. Roller Bearings. Thin-Profile Crossed-Roller Bearings.
    For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.
    Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

    Spherical-Roller Bearings

    Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.

    High-Load Crossed-Roller Bearings

    The thicker inner and outer raceways on these bearings can handle heavier loads than the thin-profile crossed-roller bearings. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.

    Washers

    Small but mighty, our thinnest rolling thrust bearings slot into tight spaces and spin at whirring speeds. Their long, slender rollers support thrust loads and reduce friction in everything from machine tool spindles to gearboxes.
    A cage holds the rollers in place. You can install these bearings without washers between hardened, ground surfaces for the thinnest profile. If you’re working with unhardened, unground surfaces, you’ll need two washers for the rollers to run on. This three-piece design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.
    Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

    Washers for Needle-Roller Thrust Bearings

    Image of Product. Front orientation. Thrust Roller Bearing Washers.
    These hardened steel washers protect softer shafts and housings from the rolling contact of needle rollers. Without them, needle rollers can indent and score unhardened surfaces, leading to premature wear and bearing failure. Positioned between the bearing and each mating surface, these washers distribute thrust loads evenly and extend service life. They adapt needle-roller thrust bearings for unhardened, unground surfaces.
