Norbar Torque Tools, Inc. Datasheets for Gearboxes and Gearheads

Gearboxes and gearheads, also called gear reducers or speed reducers, are power transmission devices that use a gear arrangement in an enclosed housing to transfer energy, increase torque and reduce speed from one device to another. Gearboxes may also be referred to as gear reducers or speed reducers.

Product Name Notes
Handtorque models HT30, 45 and 60 have all the features of the standard series, but have a higher torque output for a given gearbox diameter.
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...

The 'Highwayman' torque multiplier has been designed for use where it is necessary to provide higher torques than would otherwise be possible due to limitations of space or operator strength.
Features Robust construction means minimal maintenance and long life. True 15.5:1 or 26:1 torque multiplication, accuracy guaranteed better than +/-4%. High ratios allow the use of a small torque wrench.
