    Light Duty Unthreaded Spacers

    Image of Product. Front orientation. Spacers. Light Duty Unthreaded Spacers.
    An economical choice for low-load applications. Made from low-carbon steel, these spacers have a lower tensile strength than standard steel spacers. Unlike standard versions that are often cut from seamless tubing, these are formed by molding flat-coil steel into shape. This process creates a thinner spacer with a visible seam that’s best for light duty tasks.
    Zinc-Plated Low-Carbon Steel—A common choice for areas with occasional exposure to moisture.
    Galvanized Low-Carbon Steel—Resist moisture better than zinc plating but may degrade when exposed to salt water and chemicals.

    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.

    Hollow Push-In Bumpers

    Image of Product. Front orientation. Bumpers. Hollow Push-In Bumpers, Style 2.

    Style 2

    Both bumper and grommet, these protect equipment from impact while routing wire or tubing through a center hole. All have stems that contract and expand for a snug fit. No fasteners are needed—just push them into a hole for quick installation.
    Ultra-Cushioning Sorbothane
    Image of Product. Front orientation. Bumpers. Hollow Push-In Bumpers, Style 2.

    Style 2

    Our softest bumpers have a feel that ranges from the softness of a gel insole to the firmness of a pencil eraser. They’re often used to cushion fragile materials. These bumpers boast shock-absorbing properties, making them a smart choice for mounting sensitive electronics.
    Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
