Rotary Shaft Seal 160x190x12 NBR TC - Double Lip Oil Seal

Main Description:

The Rotary Shaft Seal 160x190x12 NBR TC is a double lip oil seal designed for demanding industrial and automotive applications where reliable shaft sealing is essential. Manufactured from high-quality NBR (nitrile rubber), it ensures exceptional resistance to oils, lubricants, and fuels while maintaining excellent flexibility and sealing performance under dynamic conditions.

This TC-type rotary oil seal features a dual-lip design: the primary sealing lip retains lubricants and prevents oil leakage, while the secondary dust lip provides extra protection against dirt, dust, and moisture. The integrated metal reinforcement enhances structural stability and ensures a secure press-fit installation into the housing bore.

With its optimized geometry and carefully engineered contact pressure, the 160x190x12 NBR double lip seal guarantees minimal friction and reduced shaft wear, resulting in longer service life and improved operational efficiency. It performs reliably in temperature ranges from -40°C to +100°C, making it suitable for most general-purpose and heavy-duty environments.

Ideal for use in gearboxes, pumps, electric motors, compressors, engines, and industrial machinery, this rotary shaft seal ensures tight sealing in rotating systems where oil and grease retention is critical. Its balance of mechanical strength and chemical resistance makes it a trusted component in hydraulic, pneumatic, and automotive systems worldwide.

Applications

The 160x190x12 NBR TC oil seal is widely used in:

• Industrial gearboxes and power transmission systems

• Hydraulic pumps and compressors

• Electric motors and drive shafts

• Agricultural, construction, and mining machinery

• Automotive engines, gearboxes, and axles

This rotary shaft sealing ring ensures high durability and operational reliability in environments exposed to oils, lubricants, and contaminants.

• Suitable for industrial, hydraulic, and automotive applications

Technical Data

FAQ - Frequently Asked Questions

1. What is the difference between TC (double lip) and SC (single lip) oil seals?
A TC seal has an additional dust lip that protects against external contaminants, while SC seals are designed only for internal oil retention.

2. Can NBR seals withstand high temperatures?
Yes, NBR performs well up to +100°C. For higher temperatures, FKM (Viton®) seals are recommended.

3. How should I choose the correct shaft seal size?
The seal’s inner diameter must match the shaft, the outer diameter fits the housing bore, and the width must correspond to the assembly design.

4. Are NBR seals compatible with hydraulic oils and greases?
Absolutely. NBR offers excellent resistance to mineral oils, hydraulic fluids, and lubricants.

5. Can this seal be used in both industrial and automotive systems?
Yes, it’s suitable for both sectors, including engines, transmissions, and mechanical drives.
