    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.
    Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

    Thrust Ball Bearings

    For silky-smooth motion, the balls inside these bearings roll nearly friction-free. You'll often find them at the end of a shaft or between a stationary and rotating surface, such as on a propeller or rotary table.
    These bearings come as three separate pieces—one cage and two washers. The cage holds the balls in place, while the washers create a surface for the balls to roll on. This 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.
    Stainless Steel—These bearings won't degrade from water or mild chemicals, such as the ammonia in cleaning solutions. However, they're not as strong as steel bearings.

    Self-Lubricating Ejector Pin Bushings

    Image of Attribute. Front orientation. Contains Annotated. Die Bushings. Self-Lubricating Ejector Pin Bushings.
    Eject parts smoothly from your mold without liquid lubricant—these bushings reduce friction between ejector pins and plates. These bushings have graphite plugs to help the pins slide without wearing your assembly.
