Structure: Features a secondary sealing lip (outward-facing) augmented upon the primary sealing lip (inward-facing), without a spring.
Primary Lip: Prevents leakage (oil containment).
Secondary Lip: Repels dust, water, and impurity ingress.
Applications: Suitable for harsh environments with high dust and moisture levels (e.g., construction machinery, agricultural equipment, wheel hubs).
