Mounted at the ends of a fixed or transmission shaft on the machine chassis, they perform the function of force sensors and bearing for the ends of the shaft. They are used on both fixed and rotating shafts. TR transducers are supplied with the adaptor flange for fixing, with 4 M6 screws or with one central M0 or M2 screw.
