What would be the consequence of over greasing a bearing?

Over greasing a bearing leads to excessive internal pressure and can prevent the necessary flow of grease within the bearing. This condition can create a situation where the lubricant cannot adequately prevent friction and heat build-up due to the increased volume of grease, leading to overheating. The excess grease can also result in the formation of a viscous sludge, which contributes to increased friction and wear on the bearing surfaces. Eventually, this overheating can cause the bearing to fail prematurely, resulting in significant downtime and repair costs. Therefore, understanding the proper greasing techniques is critical in maintaining bearing health and operational efficiency.
