    Bearing

    Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
    Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.
    Shaft Liners—Shaft liners allow you to use the bearing on unhardened and unground shafts.

    Oil-Embedded Mounted Sleeve Bearings

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Oil-Embedded Mounted Sleeve Bearings.
    Reduce upkeep with sleeve bearings that lubricate themselves. Made from porous, oil-saturated bronze, they release a thin film of lubrication upon startup to keep shafts spinning. With no moving parts, they withstand dusty, dirty environments better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing bolts down to support shafts as they turn.
    Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.
    Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
