Spider Couplings

With two hubs gripping a rubbery spider in the center, these couplings damp vibration and transfer torque while flexing to handle misaligned shafts. The metal hubs never touch each other, so there's no need for lubrication. Also known as Lovejoy® couplings. For a complete coupling, select two hubs and one spider or two hubs, one split spider, and one retaining ring. 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.

Keyed—Mount onto shafts with a matching keyway.

Iron—Best for dry environments, since moisture will cause these hubs to rust.

Set-Screw Shaft Mount—Screws dig into your shaft for a secure hold.

Spiders

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

Buna-N—Best choice for vibration damping and shock absorption with the lowest stiffness and good tear resistance.

Polyurethane Rubber—Superior tear resistance to Buna-N and Hytrel and a good balance of stiffness and vibration damping.

Hytrel—Most direct torque transfer with the highest stiffness and least vibration damping.

Split Spiders

Unlike standard spiders, you can install these without using tools, removing hubs, or realigning shafts. Hold them in place with a retaining ring.

Retaining Rings

Press the pins on these rings into the grooves on a split spider. Then, twist to lock the spider in place and transmit torque between shafts.

High-Misalignment Tire Couplings

With a large, flexible rubber tire, these withstand the highest misalignment of any coupling while reducing vibration. For a complete coupling, select two hubs, one tire, and two bushings. Choose components of 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.

Iron and Steel Hub—Best for dry environments, since moisture will cause these hubs to rust.

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