70599 XCMG GR2605 motor grader seal
70599 is a commonly used seal in transmission, hydraulic clutch and oil circuit systems of construction machinery. It is mainly used for dynamic and static sealing of pistons, shaft ends, oil passages, end covers and other parts to prevent oil leakage and block external impurities, ensuring stable pressure of the hydraulic system and reliable operation of shifting and clutch.
Technical Parameters
- Model: 70599
- Type: O-ring seal
- Material: NBR (resistant to gear oil and hydraulic oil)
- Hardness: Shore A 70±5
- Working Pressure: Suitable for standard working pressure of construction machinery transmission and hydraulic systems
- Operating Temperature: -30℃～120℃
- Structure: Circular cross-section with good elasticity and stable resilience
- Features: Oil-resistant, anti-aging, not easy to deform, reliable sealing
Application Scenarios
Suitable for gearbox clutch pistons, hydraulic valve bodies, oil passage pins, end covers, oil cylinders and various oil circuit interfaces of construction machinery such as loaders, graders, rollers and forklifts. Used in static and low-speed dynamic sealing positions for oil sealing and pressure maintaining, adapting to vibration, high temperature and continuous oil scouring conditions.
Common Faults & Troubleshooting
- Oil leakage and pressure relief: Caused by aging, cracking, damage or installation cutting. Replace 70599 seal and check sealing groove.
- Seal failure: Permanent deformation and reduced elasticity after long-term use. Replace with new seal directly.
- Abnormal wear: Caused by burrs, impurities or eccentric installation in sealing groove. Clean and reinstall.
- High-temperature hardening: Material deterioration caused by long-term high temperature. Can be replaced with high-temperature resistant FKM seal.
