Single-acting seal
Single-acting wiper seals from Carlock Sealing are the first line of defense for your hydraulic cylinder. Designed to scrape dust, dirt, and moisture off the rod as it retracts into the system, these seals prevent contamination that causes abrasive wear on bearings and secondary seals. Our precision-engineered profiles ensure optimal contact force without increasing friction, significantly extending the service life of the entire hydraulic assembly.
Q: When should I choose an FKM wiper over a standard PU wiper?
A: Carlock Sealing recommends FKM when the system is exposed to high temperatures (>110°C) or aggressive chemical solvents that would degrade polyurethane. For general-purpose hydraulic wear resistance, PU/H-PU remains the most cost-effective choice.
Q: How does the wiper seal impact the MTBR of my cylinder?
A: A high-quality wiper seal prevents 90% of external contaminants from entering the system. By using Carlock Sealing’s precision-machined wipers, you reduce the abrasive particles in the hydraulic oil, effectively doubling the MTBR (Mean Time Between Repair) of your internal piston and rod seals.
