Failure is Sealed by Hydraulic Cylinder – The Main Causes

One of the main reason for failure in hydraulic cylinders is seal failure. Though the price of a hydraulic cylinder seal is not so high, it can become extremely expensive for loss of production and also downtime failure when the seal becomes the cause of cylinder failure. If there is an issue inside the cylinder, it is better to focus on the problems or perhaps explanations that are creating the trouble of seal failure. The principle factors behind hydraulic seal failure are as follows:

When the seal is not installed properly: It is really important to consider the following points if the seal is installed:

Cleanliness
Seal protection from cuts and nicks
Perfect lubrication Over tightening of the seal gland. This happens when during installation there’s a folding over a seal lip.
Just check whether the seal is put upside down. This’s a typical situation.
The precaution here’s being really cautious while using the hydraulic seal

When the hydraulic system is contaminated: This is one more primary explanation for hydraulic seal failure. The contamination is triggered by external elements as mud, dirt, dust, grit, ice etc. There can easily be contamination from internal problems at the same time like metal chips circulation, fluid, hoses and various other degradable system’s products break down. Rexroth dealer in Chennai are externally contaminated as a result of rod retraction. That’s exactly why proper system of a rod wiper or scraper is a good answer. The prevention of internal contamination in hydraulic seal can be done by proper filtering of fluid system. You are aware that seal is contaminated if you see scored rod and cylinder bore surfaces, too much of seal wear and also leakage etc.

Incorrect material option: When there is chemical breakdown of the content of the seal, it’s because of incorrect material selection. Yet another cause can be due to change of hydraulic system fluid. Application of non-compatible materials is one the main cause failure of seal elements. It is able to result in seal lip loss interface, seal durometer softening, too much of shrinkage and swelling. When your hydraulic seals become discolored, that is also a suggestion of chemical attack.


Heat degradation: Once you see your hydraulic seal exhibiting a difficult, weak appearance or perhaps once you see parts of the seal lip as well as body breaking way, it suggests that there’s heat degradation. Heat degradation develops caused by loss of sealing lip effectiveness. The primary reasons for this are incorrect seal material, really tall friction, very tall lip loading, and extremely in close proximity to external heat source. To be able to be able to resolve the issue of heat degradation, it’s required to greatly reduce seal lip interference, to modify the substance of seal or to boost lubrication.

Conclusion: to be able to solve the problem of hydraulic cylinder seal disaster, it is not critical that youbuy replacement seals from makers of hydraulic cylinder. Instead, it’s your hydraulic seals making companies, who could offer you with exact sized seals. If the situation keeps on occurring, seek advice from you supplier to find an answer which can greatly increase the life of your respective hydraulic seal.
