Video transcript

Using WD-40 on bearings is not recommended. WD-40 is a solvent and a mild lubricant, but it can attract dust and dirt over time, which can lead to bearing wear and tear. For effective lubrication, use a dedicated bearing lubricant that is specifically designed to reduce friction and withstand high pressure. This ensures longevity and optimal performance of your bearings.
