Working principle of steel ball torque limiter: the critical torque is controlled by precision spring, which can achieve very accurate torque value. For the same size product, different built-in springs can be replaced to determine different sliding torque. It is used for the installation of shaft at one end and transmission at the other, It can also be equipped with coupling according to customer's requirements, so as to facilitate customer's shaft to shaft connection. After eliminating overload, the reset mode is the only position in one circle (or multiple points according to requirements). It can be connected with external limit switch to output electric signal in case of overload.

Steel ball torque limiter is widely used in various automation industries such as splitter, screw extruder, automatic conveying, mechanical rubber equipment, packaging and electronic equipment.
