Scraper ring
Frequently Asked Questions
Q: What is the HL JE-136 scraper ring used for?
A: The HL JE-136 scraper ring is a sealing component that prevents contamination and leakage in hydraulic cylinder assemblies. It removes debris and foreign material from the rod surface as the piston moves, protecting internal seals and maintaining hydraulic system integrity.
Q: What material is the HL JE-136 scraper ring made from?
A: The HL JE-136 is typically constructed from polyurethane or composite elastomer material. This material provides excellent wear resistance, flexibility, and durability in hydraulic cylinder environments. It resists mineral oil, maintains performance across temperature ranges, and minimizes friction.
Q: When should the HL JE-136 scraper ring be replaced?
A: Replace the HL JE-136 when you observe hydraulic fluid leakage around the cylinder rod, visible cracks or deterioration in the ring material, or loss of sealing effectiveness. Preventive replacement during cylinder seal kit service extends system reliability and prevents contamination-related failures.
Q: What is the difference between the HL JE-136 and other seal components?
A: The HL JE-136 scraper ring is designed specifically to remove contaminants from the rod surface. Unlike primary seals (which seal pressure), the scraper ring performs a protective function. Scraper rings are typically used in tandem with other seal components like o-rings and backup rings in a complete seal assembly.
