Mechanical torque limiter SIKUMAT® ST

ball bearingcompactsafety

The positive (ratcheting) torque limiter SIKUMAT ST is a precision safety device for machines and installations. It operates ratcheting and backlash-free using the ball principle and is intended for compact shaft-mounted applications with an integral cone clamping element and bearing support.


Advantages

• Backlash-free operation in both rotation directions
• Compact design with high power density
• Integral ball bearing to support the driven component
• Very high response accuracy due to the ball principle
• Simple, backlash-free shaft fastening with integrated cone clamping element
• Calibrated micro-adjustment of the torque setting, possible even after installation

Function

• When the preset limit torque is reached, the SIKUMAT4 ratchets through
• The SIKUMAT4 automatically re-engages once the overload is removed
• Overload can be signalled by a proximity switch to stop the drive or trigger another control function
