One of the main causes of hydraulic cylinder failure is seal failure. Although the cost of a hydraulic cylinder seal is not too high, it can be very expensive for production loss and failure of downtime when the seal becomes the cause of cylinder failure.
When the seal is not properly installed: It is important to consider the following when the seal is installed:
- Seal protection from cuts and scratches
- Perfect lubrication
- Check whether the seal is placed upside down. This is a common problem.
- Precautions here are very careful when installing a hydraulic seal
When a hydraulic system is contaminated: This is another major cause of hydraulic seal failure. Contamination is caused by external elements such as mud, sand, dust, dirt, ice, etc. There may be contamination from internal problems and such as rotation of metal debris, liquid, hose, and other degradation system products damaged.

Most hydraulic systems are contaminated externally due to rod withdrawal. That's why the correct installation of eraser or stem scraper is a good solution. Prevention of internal contamination in hydraulic seals can be done by filtering the right fluid system. You know that the seal is contaminated when you see the cylindrical surface and drill rod, too much seal wear, and leakage, etc.
Incorrect selection of material: When chemical damage occurs to the seal, this is caused by the selection of the wrong material. Other causes may be due to changes in hydraulic system fluids.
Application of incompatible materials is one of the main causes of failure of the seal element. This can cause the interface to lose lip seal, soften the udometer seal, too much shrinkage or swelling. When your hydraulic seal changes color, it is also a sign of a chemical attack.
Heat degradation: When you see you’re hydraulic seal showing a hard, brittle appearance or when you see parts of the seal or body breaking method that means there is heat degradation. Heat degradation occurs because of the loss of the effectiveness of lip sealing.
