Mechanical torque limiter SIKUMAT® SG

ball bearingsafetywith clutch function

Overview
The positive (ratcheting) SIKUMAT® SG torque limiters are precision safety devices for machines and installations. They protect drives from overloads by a ball-based ratcheting action, combining precise triggering with automatic re-engagement and an integrated fixed bearing for stable mounting.

Advantages

• Very high response accuracy through the ball principle
• Integrated fixed bearing for mounting stability
• Keyway in the connecting flange for maximum torque transmission
• Calibrated micro-adjustment of torque setting possible, even after installation
• Cost-effective solution for precision overload protection

Function

• When the preset limit torque is reached the SIKUMAT® ratchets to prevent further torque transmission
• After the overload condition is removed the SIKUMAT® automatically re-engages
• An overload can be signalled via a proximity switch to stop the drive or trigger other control functions
