Making a Safer World Through Accuracy and Precision

RTU - Rotary Torque Units


 

The Rotary Torque Unit is designed to be used ‘in-line’ to limit torque for both manual and certain power-driven applications. The versatile torque limiter allows conventional hand and power tools to be easily converted into torque tools. Provides accurate process control as the unit prevents a fastener or bolt from being under and over tightened.

Repeatability within +/- 6% of pre-set torque value.

  • Reliable radial torque mechanism.
  • The mechanism ‘slips free’ when the pre-set torque value is reached, eliminating overtightening. The mechanism then automatically resets.
  • Pre-set using a torque analyzer.
  • Robust construction with corrosion-free finish.
  • CH models are suitable for chuck adaptation.
  • Non-length dependent. Bi-directional operation and are calibrated in either the CW or CCW direction.
