Specification

Description

Advantage

Perfect Fit: Developed for specified engine models with precise installation dimensions, it directly replaces original parts without additional processing.
Wear and Aging Resistance: Adopts a composite structure of high oil-resistant rubber and metal skeleton, resisting wear and deformation during long-term crankshaft rotation, extending service life.
Superior Sealing Performance: Features a double-lip design combined with a wear ring to effectively compensate for shaft surface wear, eliminating oil leakage and reducing engine failure risks.
Wide Environmental Adaptability: Operates stably under high temperature, high pressure and complex construction machinery conditions, and is not prone to failure due to temperature changes.

Performance

Temperature Resistance: Withstands high temperatures in engine operating environments; the rubber material does not easily harden or crack, maintaining sealing elasticity.
Oil Resistance: Exhibits excellent tolerance to engine oil, no swelling or corrosion occurs after long-term contact, keeping the sealing surface stable.
Wear Resistance: The combined design of the wear ring and oil seal lip reduces crankshaft surface wear, extending the overall service life of the seal.
Leak-proof Performance: The double-lip structure combined with a pre-tensioned spring forms continuous and stable sealing pressure during high-speed crankshaft rotation, eliminating oil leakage.
