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.

• Industrial Gearboxes: Prevents lubricant leakage and contaminant entry.
• Automotive Transmissions: Ensures long-term sealing reliability.
• Electric Motors: Protects bearings from dust and moisture.
• Agricultural Machinery: Resists abrasive environments and harsh weather.
• Pumps & Compressors: Maintains sealing under variable pressure conditions.

1. Optimized lip geometry:

   ◦ Computer simulation design ensures low friction and minimal heat generation.

   ◦ The main lip, spring-loaded, maintains consistent sealing force.

2. Durable construction:

   ◦ Equipped with reinforced metal skeleton.

   ◦ Precisely molded elastomer with excellent wear resistance.
