ROBOTIC AUTOMATION
Provides critical force axis de-coupling to reduce part stress during assembly
TWO-STAGE RCC ACCOMMODATOR
Lateral and Rotational Compensation
Because of the two stage configuration, the part being inserted can comply laterally and rotate around the center of compliance reducing wear of machinery and the need for highly accurate robots.
Automatic Compensation
RCC compensates for positioning errors in automated assembly, thus minimizing the required assembly forces and the possibility of parts jamming.
Variable Durometer Elastomers
Six elastomeric shear pads make RCC's stiff in compression yet relatively soft in shear ensuring more accurate side to side accommodation. Choose from four different shear pad types to achieve the best compliance for your application.
The Importance of the Remote Center of Compliance (RCC)
The critical aspect of PFA's RCC is the true de-coupling of the lateral, shear, and rotational forces. The point of de-coupling occurs at a remote point called the Remote Center of Compliance (RCC). Although other compliant devices are flexible, PFA's Accommodator provides the critical de-coupling effect necessary for critical assembly applications.
Stiffness
The RCC design allows for a trade-off between the lateral and rotational stiffness values for a given projection distance and shear pad type. The units listed have been chosen to balance these two parameters. Stiffness selection should be based on tightness of fit, payload and operating speed. Units optimized for minimum rotation and torque transmission are also available in the anti-rotation (AR) option.

Cleanroom Capability
Cleanroom class 100 is available for contamination free assembly processes as part of PFA's modular cleanroom line. Contact PFA for details.
Adaptor Plates
Blank adaptors that mate with the RCC pilot and bolt circle are available for both the machine and tooling interfaces. They are center-drilled so that the customer may adapt the unit to any mounting surface.
Shear Pads
Elastomer Shear Pads are available separately for a variety of custom compliance applications, simply ordered by name. (Example: CR35 Shear Pad)
