Built-in metal frame design • Extended service life • Simplified maintenance


The EC Series End Cover Oil Seal is a precision-engineered sealing solution designed to protect bearings and internal components from contaminant ingress and lubricant leakage in rotary equipment. Featuring an advanced double-lip design with integrated dust exclusion and primary sealing functions, it ensures reliable performance in industrial machinery, automotive systems, and heavy-duty applications.
- Dual-lip protection: The primary lip maintains lubrication; the secondary lip expels dust, dirt, and moisture.
- Premium raw materials: Made from NBR material, it is oil-resistant, waterproof, and dustproof.
- Easy installation: Designed with a precision-machined thick metal skeleton for quick and safe assembly.
- Temperature resistance: Performs stably within a range of -40°C to +100°C.
- Cost-effective: Reduces downtime and maintenance costs by extending component lifespan.
