✅ Torque rating 156 in-lb (17.6 Nm)
✅ Torsional stiffness 458 in-lb/rad (51.7 Nm/rad)
✅ Max speed 7600 RPM
✅ EPDM rubber construction; temperature range -30°F to 275°F (-34°C to 135°C)
✅ Misalignment tolerance: parallel up to 0.01 in, angular up to 1°
✅ Compatible with 4J/4JE hubs and provides 4-way flexing for shock absorption

💡 What is a 4J coupling insert used for in industrial drive systems?

In short, it fits into 4J/4JE hubs to transmit torque while damping vibration.

1) 4J/4JE jaw coupling insert for torque transmission and vibration damping 2) EPDM rubber spider provides oil resistance and temperature tolerance 3) Maintains alignment by accounting for minor parallel and angular shaft misalignment✝️
