Choosing the Right Corrosion Resistant Bearing Alloy for Highly Corrosive Medical Applications

Extremely corrosive operating environments require a thorough analysis of bearing ring materials to specify the most suitable option. While a majority of situations might ultimately call for the most common and reliable stainless steel, AISI 440C, specific applications demand a more resistant alloy, especially those that regularly expose bearings to high levels of contaminants, water vapor, or… Read more

NHBB Awarded Patent for Longer Lasting High-Speed Ball Bearing Design

The United States Patent and Trademark Office (USPTO) awarded NHBB a patent for a high-speed angular contact bearing containing a unique retainer design that reduces retainer wear and increases bearing life by up to 50% in high-speed and ultra-high-speed applications.

Retainer wear is the leading cause of high speed bearing failure, and preexisting retainer designs had yet to fully… Read more

Ball Excursion and How It Is Prevented

Uniform spacing of the ball set in a rotating bearing is critical to bearing performance and life. After all, every ball bearing—except for full complement designs—includes a cage, which positions the balls at approximately equal intervals around the bearing raceway. In some applications, however, the cage experiences a catastrophic failure by getting torn apart by the ball-set.

Such a… Read more
