(Obsolete) HT2/25 AWUR 1" sq. dr.

Norbar 'HandTorque' multipliers employ multiple stages of epicyclic gearing to give a wide range of torque outputs and ratios to suit most applications. Ratios quoted are always the torque multiplication ratio, not the velocity ratio as given for some competitor's products. For example, the velocity ratio may be 29.8:1 to give a torque multiplication of 25:1 +/-4%.

Use Our Calculators

Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas:

  1. Unit conversion to assist international measurement definitions.
  2. Torque extension for setting correct values
  3. Torque tension to identify precise levels of torque to be applied for individual applications.
