jbj Techniques Limited
Prevent damage to your machine! Torque overload is often unpredictable, and if not accounted for in machinery design, can result in significant damage to the equipment, leading to prolonged and costly downtime. SAFEMAX (R) torque limiters are designed to prevent such issues by instantly disengaging the motor side from the driven side during a torque overload. This immediate response eliminates the risk of expensive downtime. Additionally, these torque limiters, being torsionally rigid and backlash-free, enable the rapid...
