Twin Spring Coupling TSC500 Industrial mechanical power transmission couplings have no internal components unlike Universal joints or jaw couplings so no annual maintenance and can run at up to 7000 rpm.

Unlike Uni joints no greasing replacing worn bearings, and jaw coupling replacement spider inserts.

Our coupling is available in all the standard industry splines and Keyway’s for easy replacement or retrofit for OEM.

Flexible up to 25 degrees Under load (35 degrees not under load)
