FAQs

What is the difference between 2.5od x contact bearings and deep groove ball bearings?

2.5od x contact bearings have a single row of balls and a contact angle of 25 degrees, while deep groove ball bearings have two rows of balls and a contact angle of 0 degrees. This difference in design gives 2.5od x contact bearings higher load capacity and greater rigidity, but less speed capability compared to deep groove ball bearings.

What is the typical service life of a 2.5od x contact bearing?

The service life of a 2.5od x contact bearing depends on factors such as load, speed, and lubrication. However, under normal operating conditions, a well-maintained bearing can have a service life of several years.

Can 2.5od x contact bearings be used in applications with high contamination?

While 2.5od x contact bearings are not specifically designed for high-contamination environments, they can be used in moderately contaminated applications if proper lubrication and sealing measures are implemented.

Conclusion

2.5od x contact bearings are high-precision, high-load capacity components that play a vital role in a wide range of applications across various industries. Their accurate, reliable, and durable performance makes them an excellent choice for demanding applications where precision and performance are paramount. By following the guidelines outlined in this article, you can select, install, and maintain 2.5od x contact bearings for optimal performance and extended service life.
