North American electronics distributor Sager Electronics is now stocking NMB’s High Performance PWM Cooling Fans. NMB’s new series of high performance, four-wire, PWM-driven fans with tachometer signal offer high torque, efficient motor technology, and aerodynamic impeller design. Benefits of the PWM series include increased fan life expectancy, energy efficiency, lower vibration and noise, and current…
By Joyce Laird, Contributing Editor What makes flanged ball bearings different than other ball bearings? A flanged ball bearing is not truly a different type of bearing. Just as ball bearings are offered sealed or open, they are also available flanged or plain. The flange is just another option given to the design engineer by […]

By Mike Santora Unchecked vibration and noise can have real consequences in a motion system. And it’s not just the obvious reduction in bearing life that first comes to mind. Bearing noise in medical applications can create distractions for patients. It also affects the fans in air-conditioned seats in the automotive industry. In short, there […]

The Anderon meter is a device used to measure bearing vibration, often to help assess potential noise concerns. Simply put, the higher the vibration velocity measurement, the noisier the bearing is. The Anderon meter readings are separated into 3 difference frequency bands. Low, medium, and high. The low frequency band would be 50 to 300 […]
Miniature ball bearings are high precision devices compared to many mechanical parts. Good performance will therefore require treatment that takes into account their characteristics and operating environment. Edited by Mike Santora Handle with care. Literally. Just because bearings are built to last doesn’t mean they’re made for mistreatment. A high percentage of bearing problems, including […]
By Joyce Laird, Contributing Editor Ball bearings are available with and without enclosures. Richard Picard, field applications engineer at NMB Technologies Corporation explains that compared to open bearings, shielded and sealed bearings provide better protection from contamination and also add protection against lubrication migration. “The selection of a shield or seal is dependent on the […]
