Bearing Lubrication Oil vs Grease: A Technical and Engineering Perspective

1. Introduction Bearing reliability is fundamentally linked to lubrication performance. Industry data consistently shows that a significant percentage of premature bearing failures are lubrication-related—caused by improper lubricant type, contamination, insufficient film thickness, or thermal degradation. One of the most critical decisions in rotating equipment design and maintenance is whether to use lubrication oil or grease.

Hogyan befolyásolják a tengelyek felületkezelései a fáradási élettartamot: Nitridálás és karburálás mérnöki összehasonlítása

Shafts are fundamental components in rotating and reciprocating machinery, transmitting torque, supporting loads, and ensuring precise alignment. Fatigue failure is one of the most common causes of shaft breakdown, often initiating at the surface due to repeated stress cycles. Surface treatments, such as nitriding and carburizing, are widely applied to enhance fatigue life by improving
