In the field of industrial equipment sealing, stainless steel double-lip bidirectional oil seals represent a breakthrough in structural innovation and reliability. This solution effectively addresses leakage issues under high-pressure, dusty, and complex motion conditions.
I. Innovative Structural Design
1. Dual-Lip Synergistic Sealing
- Primary Seal Lip: Fluororubber (FKM) material with symmetrical bidirectional edges (≤40MPa pressure resistance)
- Dust Lip: PTFE composite layer blocks external particles >10μm (≥99% efficiency)
- Synergy: Dual protection against internal fluid leakage and external contaminants
2. Stainless Steel Skeleton Core
- Material: SUS630 precipitation-hardened stainless steel
- Key Properties:
- Yield strength ≥1000MPa (300% deformation resistance improvement)
- Thermal expansion matching metal housings (-40°C~220°C stability)
3. Adaptive Compensation
- Automatic radial interference compensation for shaft wear (±1mm)
- Rigid-flexible coupling design withstands ±3mm axial vibration
II. Performance Advantages
| Feature | Specification | Customer Value |
|---|---|---|
| Pressure Resistance | Bidirectional ≤40MPa | Suitable for hydraulic cylinders/gearboxes |
| Temperature Range | -40°C~220°C | Arctic to industrial high-temp environments |
| Dust Protection | IP6X certified | Effective particle isolation |
| Service Life | 2-5 years | >50% maintenance reduction |
