Rotary Shaft Seal 9,5x16x4 NBR TC Double Lip Oil Seal

Reliable Rotary Sealing for Industrial and Automotive Systems

TC Double Lip Design and NBR Material Performance

Technical Data and Proper Size Selection

Main Description:
The Rotary Shaft Seal 9,5x16x4 NBR TC is a compact double lip oil seal designed for precision rotary sealing in industrial and automotive assemblies. This rotary shaft seal ensures effective retention of lubricants while protecting internal components from dust, moisture and external contamination.

The size 9,5x16x4 defines a shaft diameter of 9,5 mm, housing bore diameter of 16 mm and seal width of 4 mm. Its TC double lip configuration includes a primary sealing lip for fluid control and a secondary dust lip for environmental protection. Compared to a single lip oil seal (SC type), the TC design provides enhanced shaft sealing performance in applications exposed to contamination or fluctuating operating conditions.

Manufactured from high-quality NBR elastomer, this oil seal offers excellent resistance to oils and grease, making it suitable for lubricated mechanical systems. NBR is widely used in hydraulic and automotive seals due to its balanced mechanical properties and high durability under standard temperature ranges. The flexible sealing edge maintains stable radial contact with the shaft, reducing leakage risk and minimizing wear.

This shaft sealing ring is commonly applied in small gearboxes, pumps, electric motors and auxiliary drive units. It functions effectively as an engine seal or technical seal in light-duty industrial applications where precise rotary seal performance is required. Proper installation in a clean housing bore ensures optimal performance and extended service life of adjacent components such as bearings and rotating shafts.

For B2B customers, the 9,5x16x4 NBR TC rotary oil seal represents consistent quality, predictable maintenance cycles and dependable operation in industrial applications.

FAQ

1. What is the difference between single lip and double lip oil seals?
A double lip oil seal (TC) includes an additional dust lip for contamination protection, while a single lip oil seal (SC) seals only the lubricant side.

2. Is NBR suitable for oil and grease applications?
Yes. NBR provides strong resistance to oils and grease and is commonly used in industrial and automotive sealing systems.

3. How do I select the correct rotary shaft seal size?
The first dimension corresponds to shaft diameter, the second to housing bore diameter and the third to seal width. Always match the seal to precise shaft and bore measurements.

4. In which applications is this seal typically used?
It is widely used in gearboxes, pumps, small engines, electric motors and other rotating mechanical assemblies.

5. Can this seal be used in hydraulic systems?
It can be used in light hydraulic and lubricated systems within standard NBR temperature and pressure limits.
