Miniature Ball Bearing Noise and Testing for Bearing Noise

The standard instrument used for bearing noise testing is the Anderon Meter (sometimes called Anderometer) made by Sugawara Laboratories. This measures noise with an accelerometer contacting the outer race of the bearing while the inner race is rotated at 1800 RPM. Noise levels are separated into 3 bands, designated as follows: High band 1,800
