Wiper WED
WED wipers are polyurethane protective seals for hydraulic cylinder rods, with a profile optimized to combine cleaning efficiency with additional sealing against contaminants. They are used in hydraulic cylinders in mobile and stationary industries, in applications with moderate to high exposure to dust, mud, and moisture.
The role of WED wipers in protecting hydraulic cylinders against dust and external impurities
WED wipers clean the rod during retraction and form an additional barrier against contaminants that could penetrate toward the internal seals. The optimized profile ensures close contact with the rod, without excessive pressure that could cause premature wear of the chrome-plated surface. You can find the complete catalog of hydraulic wipers on hydsealstore.ro.
Characteristics of the polyurethane used in WED wipers: elasticity, sealing, and wear resistance
Polyurethane is selected for its resistance to abrasive wear and for its elastic behavior that maintains contact with the rod throughout its service life. WED operates at temperatures between -30°C and +110°C and is compatible with mineral hydraulic oils and some biodegradable fluids. The lip does not permanently deform after repeated cycles. Also compare with WNM wipers made of polyamide for rods with substantial adhering deposits.
How to identify the correct WED wiper size and avoid choosing an incompatible version
Sizing a WED wiper is based on the rod diameter, the outer diameter of the housing, and the groove depth. An incorrect choice compromises operation and can damage the rod or the mounting groove. They are replaced preventively during each scheduled cylinder overhaul. Also compare with BWA wipers for applications where preliminary cleaning of the rod is a priority.
