Air Screwdrivers & Nutrunners
Selection of the appropriate clutch arrangement for your application is one of the first critical steps in specifi cation. IR offers four basic types — adjustable precision shut-off, adjustable cushion clutch, positive jaw, and stall. The following introduction, coupled with the “Types of Joints” table on the following page, will help you defi ne your requirements.
Adjustable Precision Shut-Off Clutch
Designed for critical fastening applications involving plastics, composites, or metals that require precise torque control. Automatic shutoff reduces air consumption and torque reaction.
Adjustable Cushion Clutch
Steel balls rolling between indented plates provide smooth disengaging at preset torque while minimizing vibration to the operator. Very good general-purpose torque limiting clutch.
Positive Jaw Clutch
Designed for applications where driving torque may exceed final seating torque as in wood and self-tapping applications. Applied torque is controlled by the operator and can be limited by regulating air line pressure.
Stall
Designed for soft pull applications in wood and other materials not requiring critical torque control. Applied torque is controlled by the operator and can be limited by regulating air line pressure.
