Rotary Shaft Seal 130x160x12 NBR SC - Single Lip Oil Seal

Main Description:

The Rotary Shaft Seal 130x160x12 NBR SC is a single lip oil seal engineered to provide effective sealing for rotating shafts in mechanical systems exposed to oils, greases, and lubricants. Made from premium NBR (nitrile rubber), this seal ensures outstanding performance, long service life, and reliability in both industrial and automotive applications.

The SC design (single lip with metal casing) provides a secure and tight fit in the housing while maintaining low friction on the shaft surface. The sealing lip is precisely molded to maintain consistent contact pressure, ensuring oil retention and protection against leakage. The metal-reinforced structure improves mechanical stability and resistance to deformation, even under high rotational speeds.

This 130x160x12 NBR oil seal is widely used in gearboxes, pumps, electric motors, compressors, hydraulic systems, and agricultural machinery. It offers excellent resistance to oils, greases, and fuels while maintaining flexibility and sealing integrity in temperature ranges from -40°C to +100°C. The single lip construction makes it ideal for applications where contamination from dust or water is minimal, ensuring efficient lubrication retention and low wear.

Designed for long-term operation, this rotary shaft seal combines durability, precision, and material efficiency, making it a trusted choice in demanding industrial and power transmission systems.

Applications

The 130x160x12 NBR SC single lip oil seal is suitable for use in:

• Industrial gearboxes and drive units,

Technical Data

FAQ - Frequently Asked Questions

1. What is the difference between single lip (SC) and double lip (TC) shaft seals?
Single lip seals retain oil or lubricant inside the system, while double lip seals add a dust lip for protection against external contamination.

2. Is NBR suitable for use with hydraulic oils and fuels?
Yes, NBR offers excellent compatibility with mineral oils, lubricants, and hydraulic fluids.

3. How to choose the right shaft seal size?
Match the inner diameter to the shaft size, the outer diameter to the housing, and ensure proper width according to your application.

4. Can this seal operate under high speed or pressure?
Yes, this NBR SC rotary seal is designed for dynamic applications with moderate pressure and high rotational speeds.

5. Are there higher-temperature alternatives available?
Yes, for applications above +100°C, materials such as FKM (Viton®) or ACM are recommended.
