RAD Pneumatic Compliance Specifications

• Reduce robot* programming time
• Open up part tolerances
• Decrease scrap caused by misalignment
• Increase assembly speed
• Minimize part and tool damage caused by contact forces
• Reduce downtime and machine wear caused by parts jamming and wedging

RAD’s Pneumatic Compliance Device:

• Compensates for positional misalignment
• Is compliant in X and Y axes, radially (laterally), as well as rotationally
  PLEASE NOTE: If you require axial (“Z” axis) or angular compliance, as well as rotational, the Ultimatic™ Collision Sensor can be used as a compliance device in some cases.
• Provides precise centering to within ±0.001″ (0.025mm)
• Features a standard pneumatic ‘lock up in the center position’ function to prevent the device from floating during rapid transport and/or to disable the compliance when it’s not needed
• Allows instantaneous transition from smooth compliance to centered rigidity
• Offers no compression in the Z axis – making it ideal for applications requiring moderate insertion forces through the center line of unit
• Allows pneumatic adjustment so user can easily change the external force required to offset the movable plate

Assembly Operations

• Positioning on an assembly line
• Aligning molds
• Locating parts in machines

Insertion Operations

• Placing washers, fans, or gears onto shafts
• Inserting bearings into drive assemblies

Operating Principle
RAD’s Compliance Devices provide allowances for both lateral and rotational misalignments. This compliancy allows parts to automatically align themselves upon striking a lead-in chamfer or tapered guide. RAD Compliance Devices function through a series of bearings and pneumatic pistons.

* can also be used on linear actuators, pick & place machines, and other automated equipment.
