Highly Elastic Coupling

High-Elastic Rubber Couplings – Advanced Vibration Damping & Misalignment Compensation

JM High-Elastic Rubber Couplings are engineered all-rubber flexible couplings that deliver superior shock absorption, multi-directional misalignment correction, and maintenance-free operation for medium-power drivetrains. Utilizing vulcanized rubber-metal composite technology, these couplings protect equipment from vibration damage while accommodating installation errors and thermal growth.

Core Technology & Working Principle

✔ Torque Transmission

Metal hubs/flanges transfer torque to the rubber elastic element

Rubber deforms torsionally to transmit power smoothly

✔ Vibration Control

Natural frequency <15Hz – Effectively isolates high-frequency vibrations

Damping coefficient >0.2 – Absorbs 70%+ of shock loads

✔ Misalignment Compensation

Axial: ±5–20mm

Radial: ±0.5–5mm

Angular: ±1°–3°
