    Shim Assortments for Keyed Shafts

    Image of Product. Front orientation. Shims. For Keyed Shafts, Round, Sold as Assortments.
    When you don’t know the exact shim thickness you’ll need, keep multiple shim thicknesses for keyed shafts on hand so you always have the right one. Fit these notched shims around keyed shafts and arbors that have a key inserted. Use them on keyed shafts to precisely align and space gears, sprockets, and bearings. On keyed arbors, they’re often used to accurately space saw blades and cutters. These shims are often referred to as arbor spacers.
    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.

    Shims for Keyed Shafts

    With a notch or tab, these shims fit snugly on keyed shafts to align and space gears, sprockets, and bearings. On keyed arbors, they’re often used to accurately space saw blades and cutters.
    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.

    Fit these shims around keyed shafts and arbors that have a key inserted. They’re often referred to as arbor spacers.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.

    Unthreaded Spacers for Keyed Shafts

    Image of Product. Front orientation. Spacers. Unthreaded Spacers for Keyed Shafts.
    Lock spacers in place on keyed shafts. Align the internal slot with the shaft key to prevent independent rotation. Also known as arbor spacers.
    1045 Carbon Steel—Stronger than low-carbon steel alternatives to take on higher loads and withstand more impact. Best for dry environments since moisture will cause these spacers to rust.
