Product description

The LJ elastic coupling is a Jaw-Flex jaw coupling with a straight-leg elastomeric spider element. It is the market-standard reference for torque transmission in everyday industrial environments — pumps, fans, conveyors, machine tools.

The LJ stands out for its design simplicity, robustness and wide compatibility with competing manufacturer references (RATHI, Lovejoy, KTR Rotex, Flender Fenaflex, etc.). Cast-iron hubs are available in standard bores or custom, with keyway machined on request within 24h.

The elastic spider comes in three materials to suit the specific demands of each application: synthetic rubber for general use, polyurethane for higher torques, Hytrel for high temperatures and heavy duty.

Standard elastic spider with straight legs — proven over decades
Cast-iron hubs with standard bores or keyway machining on request
Tolerance to angular, parallel and axial misalignment
Natural damping of shocks and vibrations
Compatible with rubber, polyurethane or Hytrel spider
Stock available — custom machining within 24h
