Common Issues with NBR Seals (Simmerring) and Their Solutions

NBR seals, commonly known as Simmerring seals, play a crucial role in ensuring the efficiency and longevity of various machinery and automotive components. However, users often face several challenges when working with these seals. In this blog, we will explore the most frequent problems associated with NBR seals and provide practical solutions to help users maintain optimal performance. At simmering.pl, we offer high-quality GRN NBR seals available in a variety of sizes to meet diverse application needs.

Common Problems with NBR Seals

1. Leakage Issues

• Description: One of the most common problems with NBR seals is leakage. This can occur due to improper installation, wear and tear, or damage from contaminants.
• Solution: Ensure that the seal is installed correctly, following the manufacturer’s guidelines. Regular maintenance checks can help identify wear and replace seals before they fail.

2. Compression Set

• Description: NBR seals can experience a compression set, where the seal deforms under pressure and fails to return to its original shape, leading to leaks.
• Solution: Select seals made from high-quality NBR materials, such as those from GRN, which offer better resilience. Additionally, ensure that the operating conditions (temperature and pressure) are within the specified limits to prevent deformation.

3. Chemical Compatibility

• Description: NBR seals are resistant to many oils and fluids, but they can be damaged by certain chemicals, such as strong acids and bases.
• Solution: Always verify the compatibility of NBR with the fluids it will encounter in service. Consider using alternative materials like FKM or PTFE for applications involving aggressive chemicals.

4. Temperature Limitations

• Description: NBR seals typically operate effectively within a temperature range of -40°C to +120°C. Exceeding these limits can lead to failure.
• Solution: Monitor operating temperatures closely and consider upgrading to specialized NBR formulations from GRN that can withstand higher temperatures if necessary.

5. Installation Errors

• Description: Incorrect installation can lead to premature failure of NBR seals. Common mistakes include not properly aligning the seal or using the wrong tools during installation.
• Solution: Use proper installation tools and techniques. Training for personnel on the correct installation methods can significantly reduce errors.

6. Wear from Contamination

• Description: Dust, dirt, and other contaminants can wear down the sealing lip of NBR seals, leading to leaks.
• Solution: Implement effective filtration systems and regular cleaning of the environment where machinery operates to minimize contamination.

Conclusion

By understanding these common issues and implementing the suggested solutions, users can significantly enhance the performance and lifespan of NBR seals in their applications. Regular maintenance and proper handling are key to preventing problems and ensuring reliable operation.
