Wipers/Scrapers
Wipers/Scrapers seals clean dirt, foreign particles, metal chips, and moisture from the cylinder rod during stroke retraction. By blocking external contaminants from entering the fluid power system, scrapers prevent media contamination and protect internal components like rod seals, guide rings, and bearings from premature wear.
High-Performance Wipers
Advanced Sealing Technology offers wipers/ scrapers in a range of high-performance materials, including metallic compounds, elastomers, and polyurethanes. These materials are selected for low friction and high wear resistance. And thus preventing damage while maintaining scraping force over extended duty cycles.
