Precision Spider Couplings

Position shafts and handle misalignment on precision motors, pumps, and other equipment that requires highly controlled movements. These couplings have a hard, rubber spider to fully transfer torque from one shaft to the other (zero backlash). They're also known as precision jaw couplings. Choose components with the same trade size to ensure they'll fit together.

Hubs

The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.

Aluminum—Lightweight and corrosion resistant.

Clamp-On Shaft Mount—Grip shafts evenly without marring them and hold tighter than set screws. Tighten the clamping screws to secure.

Spiders

A flexible center fits between hubs to enable torque transfer and damp vibration.

Polyurethane Rubber—Provide a balance of stiffness and moderate vibration damping. Higher-durometer spiders are more rigid for more precise positioning, but they absorb less vibration.

Precision Beam Couplings


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

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.

Black Anodized Aluminum—One-third the weight of steel and more corrosion resistant than unfinished aluminum.

Shaft Collars with Lever

Ideal for frequent setup changes in tight spaces, these collars tighten with a lever instead of a screwdriver. Slide them from one end of your shaft and turn the lever like a ratchet to secure. To reposition or remove collars later, use the lever to loosen the screw and release the hold.
