    Precision Beam Couplings

    Image of Product. Front orientation. Flexible Shaft Couplings. Precision Beam Couplings, Spiral Cut.

    Spiral Cut

    Machined with slits, these one-piece couplings flex to transfer full torque (zero backlash) and compensate for tiny misalignments.
    Spiral Cut—Long slits along the surface help the coupling flex and handle greater misalignment than parallel cut couplings. They're also less rigid, so they're best used with light duty machinery, such as encoders and stepper drives. Also known as helical beam couplings.
    Aluminum—Lightweight and corrosion resistant.
    Set-Screw Shaft Mount—Screws dig into your shaft for a secure hold.

    Two-Piece Shaft Collars

    Image of Product. Front orientation. Shaft Collars. Two Piece, For Round Shafts.

    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.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
    Aluminum—One-third the weight of steel and corrosion resistant.

    Set Screw Shaft Collars

    Image of Product. Front orientation. Shaft Collars. 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.
    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.
