70984 XCMG GR2605 motor grader sealing ring
70984 is a special sealing element for hydraulic and transmission systems of construction machinery. Made of oil-resistant, pressure-resistant and aging-resistant elastic material, it is mainly used for sealing oil cylinders, pistons, shaft ends and oil circuit interfaces to prevent leakage of hydraulic oil or gear oil, and block external dust and moisture from entering the cavity, ensuring stable system pressure and normal operation of components.
Technical Parameters
- Model: 70984
- Type: O-ring / reciprocating seal
- Material: NBR or FKM, excellent oil and temperature resistance
- Hardness: Shore A70±5
- Working Pressure: Suitable for standard pressure of construction machinery hydraulic and transmission systems
- Operating Temperature: -30℃～120℃
- Sealing Mode: Radial or face seal with compact installation structure
- Features: Wear-resistant, oil-resistant, anti-aging, good resilience, not easy to set permanently
Application Scenarios
Suitable for gearbox clutch pistons, hydraulic valve bodies, drive shaft ends, oil cylinders, gear pumps and various oil circuit interfaces of construction machinery such as loaders, graders, rollers and forklifts. Used in dynamic or static sealing positions to prevent oil leakage and impurity intrusion, ensuring reliable operation of hydraulic and transmission systems.
Common Faults & Troubleshooting
- Oil leakage: Caused by aging, hardening, damage or installation cuts. Replace 70984 seal and inspect sealing groove.
- Seal failure and insufficient pressure: Caused by permanent deformation or wear of seal. Replace with new seal directly.
- Seizure and abnormal wear: Caused by burrs or impurities in sealing groove. Clean installation groove before replacing seal.
- High-temperature hardening: Caused by material aging under long-term high temperature. Replace with high-temperature resistant seal.
