Ball bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the …

Calculating Mill Drive RPMs: Is Your Mill Up to Speed?

Some mill lines have digital readouts for the speeds of each section as outlined in the sample drawing below. If not, then use a digital hand held tachometer as outlined in the above picture to obtain the RPM readings from the bottom driven shafts in each of the sections.

Using Vibration Analysis to Test for Bearing Wear

 · Ball-bearing wear becomes increasingly evident as harmonics (integer multiples) of these ball-pass frequency peaks occur in the vibration spectra. Depending on the nature of the defect, there also may be strong 1xM sidebands around the bearing tones or their harmonics.
