    Dry-Running Metal-Reinforced Plastic Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Dry-Running Metal-Reinforced Plastic Sleeve Bearings.
    Combine slippery plastic with the strength of metal. The PTFE core is naturally slippery, so you’ll never have to add lubricant. These bearings also keep your workspace clean with no lubricant to drip or flake and attract dust. Compared to all-metal bearings, they are lighter.
    With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
    Bronze-Backed PTFE with Steel Shell—A good all-around, economical choice. Although these bearings are stronger than aluminum, they can only be used in dry environments where corrosion is not a concern.

    Dry-Running Mounted Sleeve Bearings with Two-Bolt Flange

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Dry-Running Mounted Sleeve Bearings with Two-Bolt Flange.
    Leave the lubricant in the supply closet—these low-maintenance bearings are made from naturally slippery plastic. They'll keep shafts spinning with no messy grease to drip off, wash out, or collect dust. With no moving parts, sleeve bearings stand up to grimy environments better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing supports the shaft and secures with a two-bolt flange, the most common type of flanged bearing.
    High-Load Bronze-Backed PTFE—Reinforced with metal, these slick PTFE bearings carry load ratings at least seven times greater than any plastic alternative. The slippery material is a good fit for conveyors and other machinery with frequent starts and stops.
    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.

They'll keep shafts spinning with no messy grease to drip off, wash out, or collect dust. With no moving parts, sleeve bearings stand up to grimy 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.

    Weldable 4130 Alloy Steel Round Tubes

    Image of Product. Front orientation. Steel. Weldable 4130 Alloy Steel Round Tubes.
    Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

    With ID tolerances sized specifically for reamers, these bushings ensure steady and precise hole finishing. Press them into a fixture plate with a manual or hydraulic press for permanent installation. Also known as headless bushings, these ANSI-type P bushings don’t need counterboring to be mounted flush. They are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.
