    Wide-Rim Shims

    Image of Product. Front orientation. Shims. Wide Rim, Round, Sold Individually.
    Spread loads across a wider surface area than standard shims to minimize costly wear between components. With thickness tolerances as fine as a strand of hair, these shims precisely align, space, and level components on shafts, arbors, and machinery.
    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.
    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.
    Highly-Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these shims won't degrade when exposed to harsh weather, salt water, and most chemicals.
    Carbon Steel—Best for dry environments since moisture will cause these shims to rust.
    Zinc-Plated Carbon Steel—A common choice for areas with occasional exposure to moisture.

    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.
    Notch
    Image of Product. Front orientation. Shims. For Keyed Shafts, Sold Individually, Round, Notch.
    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.

    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.
