POWERED TORQUE TOOLS

PNEUMATIC TORQUE TOOLS

What is a PneuTorque®
Pneumatic Torque Tool?

The PneuTorque® consists of a
robust air motor driving a Norbar
multiplier with three or more stages
of epicyclic gearing.

Torque control is achieved through
adjustment of the air pressure. An
air pressure versus torque graph and
a calibration certificate is supplied
with each tool and allows specific
torque values to be set� For more
critical applications, PneuTorques
can be fitted with a torque
transducer and the precise torque output displayed. The tool can then be shut off at the desired torque either
manually or automatically using suitable control circuitry.
Why use PneuTorque® Pneumatic Torque Tools?

Hand operated torque multipliers are ideal for low volume or intermittent use or when there is no power
source available. However, for production lines or whenever a large number of bolts is involved, a powered
multiplier will save a considerable amount of time.
PneuTorque® operation is quiet – less than 85 dB(A) with absolutely no impacting. These two factors make
PneuTorques comfortable for the operator to use, reducing fatigue and consequently increasing safety.

PneuTorques provide accurate torque control – on a given joint they will stall repeatably to within ±5%
(PTS tools, ±3%). Using electronic shut off, this repeatability can be improved to ±2%.
Summary of PneuTorque® Advantages:

• Sound pressure level does not exceed 85 dB(A)
• No impacting means less damage to the tool, socket and bolted SYSTEM
