RAD's Pneumatic Compliance (Alignment) Devices lower your costs by allowing you to:

• 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 both lateral and rotational misalignment
• Offers up to ± 6º of rotation and up to ± 0.185" (4.7mm) lateral movement in any direction
• 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 by simply mounting the unit without wiring it to the robot.
• Provides precise centering to within ±0.001" (0.025mm) of true position
• Features a standard pneumatic 'lock up' function to prevent the device from shifting during rapid transport and/or 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 top 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.
