What to do if SCHUNK Industrial Equipment does not move?
- S
  Shawn JonesJul 28, 2025
  If your SCHUNK industrial equipment isn't moving, several factors could be at play. First, the base jaws might be jammed due to an uneven mounting surface, so check the evenness of the mounting surface. Ensure the pressure hasn't dropped below the minimum required; if it has, check the air supply. Also, verify that the compressed air lines are correctly connected and that any unused air connections are closed. The proximity switch might be defective or incorrectly set, so readjust or replace the sensor. If none of these resolves the issue, a component part may be defective, requiring replacement or repair by SCHUNK. Finally, in cases of lateral attachment, verify that the air or control line is not swapped and check the adapter plate.

Why is the gripping force dropping in my SCHUNK PGN Industrial Equipment?
- R
  rowereneeAug 3, 2025
  A drop in gripping force in your SCHUNK industrial equipment can stem from several causes. Firstly, compressed air might be escaping; inspect the seals and replace them if necessary after disassembling the product. Excessive grease in the mechanical movement space can also be a culprit, so clean and lubricate the product. Ensure that the pressure isn't dropping below the minimum required; if it is, check the air supply. Lastly, a defective component part could be the issue, necessitating replacement or repair by SCHUNK.

What to do if SCHUNK PGN Industrial Equipment does not travel the entire stroke?

  Patrick MurphyAug 9, 2025
  If your SCHUNK industrial equipment isn't completing its full stroke, consider these potential causes. Dirt deposits between the cover and piston could be hindering movement; clean and re-lubricate the affected area. Insufficiently flat mounting surface may be the reason, so check the evenness of the mounting surface. Check the air supply, because the pressure may be dropping below the minimum. If these steps don't resolve the issue, a component part might be defective, requiring you to send the product with a SCHUNK repair order or dismantle it.

Why is my SCHUNK Industrial Equipment opening or closing abruptly?
- T
  Timothy KiddAug 15, 2025
  Abrupt movements in your SCHUNK industrial equipment can be attributed to a few key issues. Insufficient grease in the mechanical guiding areas may be the cause, so clean and lubricate the product. Blocked compressed air lines can also lead to abrupt actions, so check the compressed air lines for damage. Additionally, an uneven mounting surface can contribute to this problem, so check the evenness of the mounting surface.

How to improve opening and closing times of SCHUNK PGN?
- L
  Linda CookNov 19, 2025
  To optimize the opening and closing times of your SCHUNK industrial equipment, consider these points: 1. If present: Open the flow control couplings on the product to the maximum that the movement of the jaws occurs without bouncing and hitting. 2. Check compressed air lines. 3. Ensure inner diameters of compressed air lines are of sufficient size in relation to compressed air consumption. 4. Keep compressed air lines between the product and directional control valve as short as possible. 5. Ensure the flow rate of valve is sufficiently large relative to the compressed air consumption. 6. The throttle check valve must not be removed, even if the product has not reached the opening and closing times. 7. If, despite optimum air connections, the opening and closing times specified in the cata...
