Wiper SCK
SCK wipers are protective seals for hydraulic cylinder rods, with a compact profile and a cleaning lip optimized for close contact with the rod around the entire circumference. They are used in hydraulic cylinders in mobile and stationary industries, in applications where effective protection against dust, dirt, and other external contaminants that could damage the internal seals is required.
The role of SCK wipers in preventing impurities from entering hydraulic cylinders
SCK wipers clean the rod with each retraction and form a physical barrier between the external environment and the area of the internal seals. Without a functional wiper, contaminants quickly reach the rod seal, causing abrasive wear and leaks. SCK is sized for standard grooves, compatible with the vast majority of hydraulic cylinders on the European market. You can find the complete catalog of wiper seals on hydsealstore.ro.
Features of the SCK profile and the advantages of using it in hydraulic systems
The SCK profile has a cleaning lip with a specific geometry that ensures close and uniform contact with the rod, with a contact force calculated for effective cleaning without premature wear of the rod surface. The standard material is NBR or polyurethane, selected depending on the application requirements: NBR for lower temperatures and various fluids, polyurethane for better resistance to abrasive wear. Also compare with DWI wipers with a metal insert for more demanding applications.
Resistance of SCK wipers to dust, dirt, and difficult working conditions
SCK wipers operate at temperatures between -30°C and +100°C and are compatible with commonly used mineral hydraulic oils. They are a reliable choice for cylinders used on construction sites, in agriculture, and in industrial installations with a moderate level of contamination. They are replaced preventively during each cylinder overhaul, together with the rod seal. Also compare with WAT wipers made of polyurethane for applications with rapid cycles.
