RW Backlash Free Torque Limiters are the high technology limiters of functional precision. It delivers backlash free transmission of motion with immediate release and high sensitivity of reaction. It can be adjusted well adjusting the pressure. The limiters allow for accurate torque regulation with the assistance of a balanced radial nut.RW Backlash Free Torque Limiters function well with the help of innovative calibration system and enable re-engagement in equidistant stage. They are assembled with a drive component and get support from ball bearing.
