Ball bearing torque limiter SIKUMAT® SB

double-rollerfriction-freesafety

SIKUMAT® SB positive torque limiters are frictionless, synchronous disengaging overload clutches with a double-roller design, used to protect machines and installations.


Advantages

• High consistency of limit torque over the operating life thanks to the double-roller principle
• Disengages on overload — separation of input and output
• Synchronous re-engagement after 360° rotation
• Transmissible torque up to 10 000 Nm
• Suitable for shaft diameters up to 125 mm

Function

• When the preset limit torque is reached, the SIKUMAT® separates input and output via a locking mechanism with integrated bearings
• After removal of the overload, the device can be manually re-engaged synchronously to the start position after 360° rotation
• Re-engagement requires application of an axial switching force to the switching ring
