Applications of the 65x85x10 A NBR SC Oil Seal

The Rotary Shaft Seal 65x85x10 A NBR SC is a single lip oil seal designed to provide reliable sealing performance in rotating machinery. Manufactured from high-quality NBR (Nitrile Butadiene Rubber), it offers excellent resistance to mineral oils, greases, and standard lubricants. This shaft sealing ring is ideal for use in industrial gearboxes, hydraulic systems, automotive engines, and mechanical drives, where maintaining lubrication and preventing oil leakage are critical.

Its single lip (SC type) design efficiently seals fluids on one side, minimizing friction and wear on the shaft surface. This makes it a practical choice for standard operating environments where contamination from external sources is limited.

Advantages and Features

• High sealing efficiency - optimized single lip geometry ensures a tight seal and smooth shaft contact.

• Durable NBR material - resistant to oils, greases, and moderate temperatures (up to ~100 °C).

• Reduced friction and energy loss - single lip design minimizes wear and extends component life.

• Versatile industrial use - suitable for engines, pumps, compressors, gear units, and transmission systems.

• Easy installation - precise dimensions (65x85x10 mm) allow quick replacement and compatibility with standard housings.

The Rotary Shaft Seal 65x85x10 SC combines functionality, durability, and cost efficiency, ensuring consistent sealing in dynamic applications.

Technical Specifications

Main Description

The Rotary Shaft Seal 65x85x10 A NBR SC is a precision-engineered oil seal used to prevent lubricant leakage and protect rotating components from contamination. Its NBR elastomer construction ensures reliable operation in contact with mineral oils and standard lubricants, while maintaining flexibility and dimensional stability.

This single lip oil seal (SC type) provides an efficient sealing barrier without the additional dust lip found in double lip designs, resulting in lower friction, reduced heat generation, and longer service life. It’s commonly applied in industrial machinery, motor drives, transmission assemblies, and hydraulic pumps, where effective shaft sealing is essential for system performance.

Engineers value this model for its simplicity, cost-effectiveness, and compatibility with standard housings. Whether used in OEM production or maintenance operations, the 65x85x10 NBR oil seal ensures consistent performance under medium pressure and moderate temperature conditions.

FAQ

1. What is the difference between single lip and double lip oil seals?
Single lip seals (SC type) focus on retaining fluid inside the system. Double lip seals (TC type) have an additional dust lip for external contamination protection.

2. Why choose NBR for oil seals?
NBR is highly resistant to oils, fuels, and greases, offering reliable sealing in most industrial and automotive environments.

3. What are the typical applications of the 65x85x10 A NBR SC seal?
It is widely used in engines, gearboxes, hydraulic units, and mechanical drives requiring standard oil retention.

4. How to select the correct rotary shaft seal?
Match the inner diameter (shaft size), outer diameter (housing size), width, and material to your specific operating conditions.
