Seal Kit Components & Engineering
| Main Component | Function |
|---|---|
| 1. Dual-Action Rod Seal (FKM) | 4-lip spring-energized design – zero leakage at ±15° rod misalignment. |
| 2. Grading-Duty Wiper (PU) | Removes hardened mud/debris (exceeds ISO 4406:2021 Level 18/16/13). |
| 3. Pressure-Tolerant Piston Seal | Reinforced U-cup with anti-roll ribs – handles 35 MPa spike pressures. |
| 4. Wear Rings (Bronzed PTFE) | Reduce metal contact by 65% – rated for 800,000 cycles in abrasive soil. |
| 5. Anti-Extrusion Rings (PTFE) | Prevent seal blowout during blade shock loads (>25° cylinder tilt). |
| 6. Port Seals (HNBR) | High-pressure O-rings for hydraulic blocks (SAE J2236 Type 3 compatibility). |
Key Features & Benefits
✅ Dual-Equipment Coverage: Single kit repairs loader lift AND dozer blade/tilt cylinders
✅ Abrasion Defense System: FKM seals with embedded particle barriers resist silicate wear
✅ Dozer-Grade Durability: Withstand 200G impact shocks during rock grading (per JD Test SD-423)
✅ Contaminant Lockout: Triple-seal defense (wiper + rod seal + particle wiper) blocks 99.5% >10μm debris
✅ Dimensional Precision: CNC-machined to ±0.01mm tolerances – no rework required
