    Oil-Embedded Thrust Bearings

    Image of Product. Front orientation. Thrust Bearings. Oil-Embedded Thrust Bearings.
    Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.
    841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.
    High-Load 863 Iron Copper—Iron makes these bearings harder, stronger, and more resistant to sudden starts and stops than 841 bearing bronze. However, they run at slower speeds. The increased iron content also makes them appear silver.
    Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away if the bearing heats up.

    Shims for D-Profile Shafts

    Image of Product. Front orientation. Shims. For D-Profile Shafts, Sold Individually, Round.
    With a partially flat inside surface, these shims won’t spin out of position to precisely align and space components on D-profile shafts and arbors.
    You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.

    Oil-Embedded Thrust Bearings for Food and Beverage

    Image of Product. Front orientation. Thrust Bearings. Oil-Embedded Thrust Bearings for Food and Beverage.
    Infused with food-grade oil, these bearings are safe for incidental contact with food. The oil is odorless, colorless, and tasteless, so they're common on food production and packaging lines. You can install and forget them since their porous surface releases oil over time. All are fabricated, lubricated, and inspected in the U.S.
    If you need a bearing rated for direct contact with food, consider dry-running thrust bearings for food and beverage.
    841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.
    Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away if the bearing heats up.

    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.

    Shim Assortments for D-Profile Shafts

    Image of Product. Front orientation. Shims. Round, Sold as Assortments, For D-Profile Shafts.
    When you don’t know the exact shim thickness you’ll need, keep multiple shim thicknesses on hand so you always have the right one. With a partially flat inside surface, these shims won’t spin out of position to precisely align and space components on D-profile shafts and arbors.
    You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.
