Schunk Inc., Morrisville, NC, has introduced two-axis compensation units. The AGE-F is self-centering using spring force and compensates for deviations of up to 5mm in the X and Y axis. Three spring rates are available for each of four sizes, which can be preloaded to specific sizes through an adjustment screw.
The AGE-E has elastomer pads that allow the unit to compensate for deviations of up to 4mm in the X and Y axis, and angular compensation of up to 3.5in. An optional pneumatic centering lock enables the unit to be held rigidly on-center when needed. The unit is available for direct mounting to PGN+, PZN+, JGP, and JGZ grippers from sizes 50 up to 200.
