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)

Lovejoy L-190 1 1/2" jaw coupling replacement (Hytrel/Bronze models) by the TSC500 500 ft lbs replacement for Jaw couplings in any industrial power transmission application.

Couplings in an industrial power transmission setup have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology, industry has evolved but the technology that makes up the standard jaw coupling. Twin Spring Coupling offers something different. Industrial power transmission is broken into two main areas, high speed low angle of misalignment and lower speed higher angle of misalignment. Traditionally these two needs have been service by two different couplings - Motion control couplings like elastomeric type couplings and the universal joint. No worn spider or inserts to replace. Twin Spring design absorbs vibration. Flexible as a universal joint. Torsionally rigid for high speed applications. One piece design. Replaces. KTR, SIT, Altra Motion, Belden, Rexnord, Lovejoy, TB Woods, Guardian Couplings, Ruland, Boston Gear.
