What to Know About Bearings

Bearings are used in a lot of different machines and equipment, but how much do you really know about them? The general definition for bearings is that they are used to prevent metal-to-metal contact between two parts by reducing friction and constraining relative motion to only the desired motion. By that definition, we can see the importance of them in many machines, especially high-speed spindles. With over 20,000 rpm, metal-to-metal contact would lead to a large amount of wear on the various parts, which would then result in repairs and replacement. High-speed spindles almost always ...

However, the two most common causes of spindle failure that we have seen here at FISCHER USA are Vibration and Peripheral Support System Failure. As a spindle manufacturer, we know that vibration is present in any milling process. However, spindles generally experience vibrations ranging from 0 mm/s to 10 mm/s. When the vibration levels increase above normal for an extended time, the vibrations can cause damage to the various components. The component that is most often damaged due to vibrations is ...
