Causes of Slew Bearing Noise

[SanStephanie]

Slew bearing noise can be caused by uneven mounting surfaces, impurities inside the slew bearing raceway, or insufficient lubrication. Uneven Mounting Surface: If the flatness of the mounting surface does not meet requirements, it can create negative clearance in the raceway, leading to noise. Improper installation, whether too tight or too loose, can also cause slew bearing noise. Impurities Inside the Slew Bearing Raceway: Particles such as sand or metal shavings inside the slew bearing raceway can cause noise. In such cases, the machinery often struggles to operate properly. Insufficient Lubrication in the Slew Bearing: Check if the raceway lacks lubrication. If so, adding lubricant can reduce friction between components.
