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.
Splined—Grooves on the hub fit with splines on a shaft.
Iron—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.

Splined-to-Keyed Spider Couplings
 |  |
Diameter |
Connect heavy duty machinery with splined shafts to components with keyed shafts—a hydraulic pump and an electric motor, for example. A central spider damps vibration, absorbs shock, and adjusts for misalignment. No lubrication required. For a complete coupling, select two hubs and one spider. 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—Best for dry environments, since moisture will cause these hubs to rust.
