The Lovejoy D-8 universal joint coupling is a slow friction bearing universal joint, only capable of 1750 RPM.

At Twin Spring we have a no greasing/bearing replacement. The Twin Spring design absorbs vibration and one ball bearing allows the coupling to flex to 45 degrees.

Offering high speed (Up to 7000 rpm) and high torque (up to 500ft lbs. nominal static torque)

The Twin Spring Coupling is a great maintenance free replacement for the Lovejoy D-8

TSC300 industrial a 300 ft lb replacement for flexible coupling and universal joint in any industrial power transmission application.

Twin Spring Coupling offers something different. Industrial power transmission is broken into two main areas Motion control couplings like beam, bellows, jaw, elastomeric type couplings and the universal joint. Of the universal joint there are 2 versions available in the industrial sector, the Block and Pin (1800 RPM max) and Needle bearing (requires constant greasing), this makes the TSC300 industrial a longer lasting more flexible higher torque and with the same splines used now a easy replacement.

TSC300 Industrial 1/2" coupling

300 ft lb replacement for mechanical power transmission couplings and universal joint 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 coupling and universal joint has not. 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 beam, bellows, jaw, elastomeric type couplings and the universal joint. No bearings to grease or replace. No worn spider or inserts to replace. Flexible as a universal joint. Torsionally rigid for high speed applications. One piece design.
