| Selection of the appropriate clutch arrangement for your application is one of the fi rst 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 fi nal 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. |  |
