    Two-Piece Rigid Shaft Coupling Bridges

    When your shafts are not close enough to use standard couplings, these have the length to bridge the gap. Install them anywhere on a shaft without removing components or having access to the ends of the shaft. Tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

    Set Screw Shaft Collars

    Slide these traditional collars from one end of the shaft and tighten the set screw. They dig into the shaft for a secure hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.
    Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
    Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.

    Slide these collars from one end of your shaft and tighten the clamping screw. They grip firmly and evenly without marring the shaft, so you can reposition or remove them later.

    For Round Shafts

    Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.
    Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
    Chrome-Plated Carbon Steel—Resist moisture and mild cleaning solutions better than zinc-plated collars.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
    316 Stainless Steel—More corrosion resistant than 303 stainless steel collars. These collars withstand salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.
    Aluminum—One-third the weight of steel and corrosion resistant.
