In a bearing, what happens if you use soft grease?

Using soft grease in a bearing can lead to higher temperatures during operation. Soft grease has different viscosity and performance characteristics compared to the appropriate type of grease that is typically recommended for bearings.

When softer grease is utilized, it may not provide adequate lubrication under load or at higher speeds. This can result in an insufficient lubricating film between moving parts, leading to increased friction. As friction rises, so does the temperature within the bearing. Consequently, operating at higher temperatures can accelerate wear and tear, potentially shortening the bearing's lifespan and reducing its efficiency.

While it's possible for a bearing to turn with soft grease, normal operation is hindered by the potential for overheating due to excessive friction. Therefore, understanding the impact of lubricant properties on bearing performance is crucial to maintaining optimal functionality and longevity in power transmission systems.
