Wipers or scrapers are an integral part of the sealing system. Their role is to ensure the cylinder chamber remains free of contaminants such as moisture, dust and debris. The presence of these contaminants can result in damage to the other parts of the sealing system or to the rod itself. This sealing solution works to ensure efficient performance.
Effective and appropriate wiper seals must be used to ensure the effective scraping of the cylinder, whilst avoiding levels of interference that affect the performance of the hydraulic system. Consideration of the seal’s environmental application is imperative.
