Key Performance Advantages:
- High-Grade NBR Resilience: Specifically formulated with NBR nitrile rubber (-30÷100°C) for excellent resistance to mineral oils, hydraulic fluids, and grease, maintaining elasticity and structural integrity across diverse temperature ranges.
- Pressure Stability: Engineered to operate effectively under working pressures of up to 10 bar, ensuring a consistent leak-proof barrier in pressurized hydraulic and mechanical systems.
- Double Lip Protection: Features a primary spring-loaded sealing lip for maximum oil retention and a secondary auxiliary dust lip that acts as a robust shield against external contaminants.
- Efficient Lubricant Retention: The spring-loaded sealing lip ensures consistent radial pressure on the 20 mm shaft, effectively preventing oil leaks even under continuous mechanical rotation.
- Precision Housing Fit: Designed for a stable interference fit within 40 mm housings, compensating for thermal fluctuations and preventing seal migration.
