Specification

Description

Advantage

User-Friendly Installation: Equipped with a red protective sleeve, no additional tools are required during installation, avoiding scratches on the lip caused by shaft keyways or threads, and significantly reducing installation failure rates.
Precise Fit: Strictly matches original equipment dimensions for direct installation without modifications, ensuring a perfect fit with the crankshaft and housing of corresponding models with no gap risks.
Durable Materials: Made of high-temperature and oil-resistant rubber with a reinforced frame, it resists deformation and aging during long-term operation for extended service life.
Reliable Sealing: The specially designed lip adjusts contact pressure adaptively with crankshaft speed, maintaining reliable sealing from idling to high-load conditions and eliminating oil seepage and leakage.

Performance

Wide temperature resistance range, adapting to the harsh high-low temperature alternating environment in the engine compartment without affecting sealing performance.
Excellent oil and wear resistance, resisting swelling and hardening from long-term oil contact with low lip wear for long-lasting sealing.
High dimensional accuracy with strict coaxiality control, preventing uneven wear and abnormal noise during operation to ensure stable crankshaft rotation.
Versatile for various working conditions, maintaining stable sealing performance in both normal and heavy-load operations to reduce the risk of downtime.
