Dynamic seals
1500BAR High-pressure / High-strength material / Special heat treatment / Multi-layer steel wire winding / Self-tightening seal / Precision forging / 100% inspection / Quick connect/disconnect / Long-life design
Product Overview
Dynamic seals are designed for sealing applications involving relative motion, including oil seals, piston seals, rod seals, and rotary seals. Featuring low-friction materials and optimized lip designs, they maintain superior sealing performance under high-speed and high-pressure conditions. Widely used in hydraulic cylinders, pumps, motors, and other rotating or reciprocating equipment.
Key Features
Optimize lip geometry to reduce the friction coefficient by 30% and minimize energy loss.
Constructed with polyurethane and PTFE composite materials, wear resistance and service life are extended by 2–3 times.
Rotary sealing line speed up to 15 m/s; reciprocating motion frequency up to 5 Hz.
Features a retaining ring design, improving anti-extrusion performance under high-pressure conditions by 50%.
Some products contain solid lubricants and are suitable for boundary lubrication conditions.
Open or split design for easy on-site installation and replacement
