    Thrust Bearings

    Image of Product. Front orientation. Thrust Bearings. Thrust Bearings.
    With no moving parts, these bearings are the plainest way to support thrust loads while reducing friction. They don't come with lubricant, so you can choose the oil that's best for your application. Make sure to mount them where they're easy to access, since you'll need to replenish the oil frequently. All are fabricated and inspected in the U.S.

    Steel

    The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
    Machine Key—Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.
