| Basic Technical Parameter |
| Bearing acoustical noise is a function of both the bearing itself and the way in which it is used. Bearings can be specified as 100% noise-tested during manufacture. Bearing noise is not generally influenced by ABEC precision, but rather by manufacturers’ internal quality standards, particularly raceway finish. There are no fixed reference standards among manufacturers for noise testing. |
| External factors affecting bearing noise include lubricant type, excessive load, improper fitting, preload method, and other factors. In particular, it is recommended that the stationary ring always be securely immobilized during high speed rotation. |
