TCU Compensation Unit

Automatic insertion or gripping of precise components is often a challenge. To be successful, the components have to be exactly aligned with one another. This results in high investment for the customer to ensure proper alignment. Even if components have very tight tolerances, it can be difficult to find the mounting or insertion position reliably. With the TCU compensation unit from SCHUNK, the users are able to overcome these challenges.

The system of SCHUNK, the leader in automation components, consists of two base plates, which are connected with each other via elastomer pads. Therefore, the compensation unit can compensate in the X, Y and to some extent Z directions. Even an angular error or a rotational error can be corrected, if required. Depending on the size of the unit, the compensation path in X/Y-direction can be 2 to 4 mm, the compensation angle can be between 1.5° and 3.5°. Optionally, SCHUNK can equip the TCU with a pneumatic locking device, which locks the module rigid. This prevents the attached tooling or gripper from being moved during actuation of the handling system.


SCHUNK is a family owned operation and a global player in one. Totaling more than 60 years of experience, SCHUNK is a leading worldwide manufacturer of toolholding components, workholding systems, and automation components.
