Under what conditions do rolling bearings use grease lubrication? What issues should be noted?Rolling bearings are lubricated with grease under the following conditions:1. Load conditions: Rolling bearing grease lubrication is suitable for low-speed and low load operation. Specific conditions includ Read More »

Why is pitting corrosion prone to occur on rolling bearings, and what are the typical phenomena?The main reason for pitting corrosion on rolling bearings is material fatigue. Pitting corrosion is caused by the contact stress generated between the rolling elements and the inner and outer raceways of Read More »

Why is the contact stress cycle characteristic of rolling bearings pulsating?The fatigue resistance of mechanical component materials is determined through testing, which involves adding a certain stress ratio of equal amplitude variable stress to a standard specimen of the material. This is usually Read More »

What is the function of gear pump shaft sleeve?The YHB gear pump often gets stuck due to various reasons. The YHB gear pump may experience the locking of the shaft sleeve and shaft diameter clearance, and the radial clearance of the sliding bearing has an impact on bearing overheating faults. The ra Read More »

What are the reasons for bearing heatingThe main reasons for bearing heating include the following:Poor lubrication: If the lubricant for the bearing is not selected properly or the oil level is insufficient, it can cause frictional heat to be generated during the operation of the bearing, resulting Read More »
