Wiper WAT
WAT wipers are polyurethane protective seals for hydraulic cylinder rods, designed for applications with frequent repeated rod movements. Polyurethane provides them with superior resistance to mechanical wear compared to wipers made of NBR or standard rubber, which makes them suitable for cylinders with intensive operating cycles — presses, lifting systems, fast-stroke cylinders.
The function of WAT wipers in keeping the rod clean and protecting the internal components of the hydraulic cylinder
WAT wipers clean the rod during retraction and block external contaminants before they reach the internal seals. Proper functioning of the wiper directly extends the service life of the rod seal and the entire cylinder sealing system. You can find the complete catalog of hydraulic wipers on Hydraulic Seals Store.
Advantages of the polyurethane material used in WAT wipers for applications with repeated movements
Polyurethane has significantly higher resistance to abrasive wear compared to NBR or rubber. Under intensive operating cycles, the polyurethane lip maintains cleaning efficiency for a longer period and does not permanently deform after thousands of retraction cycles. Resistance to mineral hydraulic oils is good, and operation within the -30°C / +110°C range covers the vast majority of applications. Also compare with SCK wipers for applications with moderate contamination.
Technical characteristics of WAT wipers and compatibility with different types of hydraulic cylinders
WAT wipers are sized for standard grooves and are compatible with cylinders in mobile and stationary industries. The compact profile allows easy installation without specialized tools — the lip must be oriented outward. They are replaced preventively during each cylinder overhaul. Also compare with WEL wipers with a thin profile for limited installation spaces.
