The Pneumatic Torque Wrench: Advantages And Applications

Compared To Other Torque Wrenches

The pneumatic torque wrench uses compressed air for its drive. There is a high-ratio gearbox inside that converts the fast, high-pressure flow of air into a strong, slow movement. This allows very high accuracy and can ensure that a nut is tightened to within a few percent of the target. Alternatives to the pneumatic system are hydraulic, electric and manual wrenches. Each of these will work, but none is as convenient or as versatile as the pneumatic torque wrench. Pneumatic wrenches are usually smaller, lighter and easier to use than the alternatives, and are very common in factory applications where high-pressure air is readily available.

Applications

High-performance machinery often requires very tight tolerances, not only in how carefully the parts are machined but also in how tightly they are fitted together. Any elaborate system of moving parts must be tightened enough that the movement is controlled and predictable but not so much that its freedom is impeded. Over-tightening can be just as damaging as under-tightening. Examples include motors and gear assemblies. A high quality wrench with a controllable slipping point allows very quick and reliable tightening to an exact torque, which ensures that the manufacturing tolerances are preserved and this eliminates guesswork on the part of the tightener.
