Formulated from a high-saturation NBR compound, this elastomeric seal exhibits exceptional chemical resistance to alkaline detergents, fabric softeners, and surfactants at elevated temperatures. The compound is specifically vulcanized to minimize swelling and hydrolytic degradation under continuous water immersion. Additionally, the NBR matrix is enriched with friction-reducing agents to mitigate heat generation at the shaft interface, ensuring the lip maintains its structural geometry and elasticity over thousands of wash cycles.

Achieving a leak-free seal relies heavily on proper hub integration. This 35*65.55*10/12 mm profile features a dual-height outer shell that ensures precise, parallel seating within the counterbore without requiring specialized heavy machinery. The flexible NBR outer diameter accommodates minor housing imperfections, offering a low-friction press fit that prevents casing distortion. For long-term maintenance-free operation, the internal lip cavity should be packed with a waterproof, lithium-base grease during installation to eliminate dry-running during initial startup.
