What Is A Nut Runner Machine?

One instrument of the industrial torque wrench family, the pneumatic torque wrench (sometimes called a nut runner) is used to tighten screws, bolts, and nuts in applications where torque is essential. Torque wrenches are different from conventional wrenches in that they can apply a specific amount of torque to a bolt. Operators can make sure they’re successfully fulfilling the project specifications for a task or project by measuring the tightness of a bolt.

A nut runner machine dates back to the 1930s and is a strong air motor coupled to a torque multiplier or gearbox. In this article, you will understand when using a nut runner is essential and how to make sure it offers the highest precision.

Applications Of Nut Runners

  • When a bolt or nut must be precisely tightened, pneumatic torque wrenches are frequently utilized in the heavy construction sector.
  • Power generation, mining, steel, railroads, and manufacturing are a few examples of these businesses.
  • ¬†Nutrunners are a safe choice for tasks requiring flammable liquids, gasses, and chemicals when they run on pneumatic power.

What Sets A Pneumatic Torque Wrench Apart From A Standard Impact Wrench?

Because of their striking similarities, a pneumatic torque wrench and normal impact wrench are frequently misunderstood.

  • ¬†An industrial torque wrench driven by continuous gearing is called a pneumatic torque wrench. Nut runners are intended to apply an essential torque specification to commercial bolts.
  • A normal impact wrench is referred to air wrench. It builds power in a mass that spins and releases it against the shaft that produces power in tiny increments, or “hammers.” Impact wrenches are frequently employed in general maintenance or assembly work.

Methods To Ensure Your Pneumatic Torque Wrench Is Accurate

Pneumatic wrenches are employed by nut runner gun manufacturers in india in heavy industry, where precision is essential. Your tool is calibrated correctly. Negative results can arise from a nut runner that is incorrect or calibrated.

  • Safety

Precise bolt tightening is essential, particularly for projects requiring infrastructure or potentially dangerous materials. A decent pneumatic torque wrench should have a repeatability of two per cent and accuracy of plus or minus five per cent. The following three elements can significantly affect a nut runner’s accuracy:

  • Tool Caliber

Pneumatic air motor-equipped gearboxes comprise the intricate instruments known as nut runners. Poorly made tools can be very error-prone because they have so many moving parts. If the tool is used, ensure that it’s in good condition or of high quality if it’s new. Verify that each gear in the gearboxes has a bearing, and assess the gear grades.

  • Air Purity

It is essential to make sure that only pure, high-quality air is utilized to power the wrench since air drives the motor and rotates the gearbox.

Damp or unclean air might lead to issues or damage over time. For the tool to perform as intended. There is sufficient air used for powering the motor.

  • Calibration

 Regular calibration and verification of a pneumatic torque wrench is the most effective approach to guarantee its accuracy.

Numerous service providers possess calibrated measuring devices and are capable of verifying the accuracy of this wrench through measurement. Regular measurement and calibration are necessary since only well-maintained tools can fulfil project requirements. Make sure your tool is certified with an ISO17025 calibration certificate to ensure it is operating correctly.
