Stahlwille 96521068 7706-8PC Complete calibration system, 3/4″ Drive

The special power transmission system prevents the force application point from shifting. The handwheel drives a lever linearly via a spindle, converting this movement into a rotary motion for the transducer. Two ball-bearing bushings provide a friction-free contact surface and allow horizontal alignment of the wrench. The torque wrench remains in position while the load is applied. Minimal transverse forces and reduced friction help to minimize measurement errors.
