Wiper WDA
WDA wipers are polyurethane protective seals with a specific profile, designed for uniform contact around the entire circumference of hydraulic cylinder rods. The shape of the WDA profile ensures an equal distribution of the cleaning force over the rod surface, eliminating areas of insufficient contact that would allow contaminants to pass through. They are used in industrial and mobile hydraulic cylinders with moderate to high demands.
The shape of the WDA profile and uniform contact with the rod for removing impurities
The WDA profile maintains complete contact of the lip with the rod around the entire circumference, including under conditions of vibration or imperfect alignment. Uniform contact eliminates areas where dust or mud could penetrate without being cleaned during retraction. You can find the complete catalog of wipers for hydraulic cylinders on hydsealstore.ro.
Resistance of polyurethane WDA wipers to wear, vibrations, and repeated operating cycles
Polyurethane maintains its mechanical properties after thousands of operating cycles. It resists abrasive wear and vibrations transmitted through the equipment structure. It operates at temperatures between -30°C and +110°C and is compatible with mineral hydraulic oils. It does not show permanent deformation after repeated cycles under temperature variations. Also compare with WIP wipers for industrial applications with similar requirements.
Selecting the correct size for WDA wipers according to the installation characteristics
The selection of a WDA wiper is based on three parameters: the inner diameter (of the rod), the outer diameter of the housing, and the groove depth. An undersized wiper does not completely clean the rod; an oversized one generates excessive friction. Preventive replacement together with the rod seal during each overhaul is recommended. Also compare with WNM wipers made of polyamide for rods with adhering deposits.
