Curve jaw coupling

Compact, flexible elastomer couplings transmit high torque.

Curve Jaw couplings are elastomer couplings characterised by their compact design and fail-safe operation. These couplings are engineered to transmit high torques despite their low weights and inertia. With long service life and sound operating characteristics, torsionally flexible couplings are a reliable choice for various applications.
