Shear bolt torque limiter, fork for cardan shaft with cross measurement 32 x 76 mm. Technical features: W 2400 cardan series type KB 61/20 diameter 156 mm image size a: 48 mm hub connection with button: 1 3/8 Z6 calibration 1600 Nm cross measurement: 32 x 76 mm M8 bolt Torque limiter operation: The characteristic of the safety system is given by the limitation of the torque which is guaranteed by the shearing of a bolt. When the torque exceeds the power that the bolt can bear, it shears and the transmitted power is eliminated. The limiter varies based on the distance from the joint axis, the bolt diameter and the strength class. Once the bolt has been sheared, a ring of spheres guarantees the free rotation of the parts without causing the parts to separate. To then restore the transmission you will have to replace it with one of the same resistance, diameter, thread and length._x000D_Brand Walterscheid Applications Round balers - Harrows - Cutter Weight 3.9 kg
