Performance details

Bearing Vibration

Measuring vibration is an effective method of ascertaining how well a bearing is manufactured. High-frequency vibration levels, often called spike energy, detect minute microscopic flaws in rolling element bearings. The results below show a typical wheel bearing after 4000km of use. Lower values indicate a superior life and reduced losses from friction losses.
