Analysis of the difference between imported bearing rolling track and grease

**Analysis of the Difference Between Imported Bearing Raceway and Grease** Home > Bearing Knowledge > Isolation Method of Imported Bearing Rolling Track and Grease *Source: Bearing Network | Time: April 3, 2013* --- Understanding the differences between the raceway of imported bearings and their grease is essential for maintaining performance and longevity. The rolling track, which refers to the surface where the rolling elements (such as balls or rollers) make contact, plays a critical role in the bearing's operation. In imported bearings, the raceway is typically designed with a smooth, polished surface. This is because the rolling elements move in a tumbling motion, creating a darkened area on the raceway due to friction. However, if the raceway shows signs of wear, such as uneven surfaces or abnormal markings, it could indicate improper load distribution, misalignment, or excessive axial or moment loads. These issues can lead to premature failure if not addressed promptly. When inspecting an imported bearing, it’s important to carefully examine the raceway. If you notice that the bearing only bears a single direction of load, or if there are inconsistencies in the housing, this may be a sign of improper installation or operational stress. If these issues aren’t corrected early, they can significantly reduce the bearing’s lifespan. Other factors contributing to early damage include lack of lubrication, contamination from foreign particles, incorrect assembly, and shaft deflection. These problems can lead to severe wear and eventual failure. Additionally, unexpected loads or device misalignments can also cause damage, making it crucial to trace the root cause of any issues. Proper analysis of the bearing’s usage conditions, including the surrounding environment and the machine’s layout, is key to preventing future failures. By understanding the working conditions and ensuring correct installation, we can minimize the risk of repeated damage and extend the bearing’s service life. --- **Methods for Distinguishing Grease Quality** 1. **Hand Rubbing Test** Take a small amount of grease between your thumb and index finger and rub them together. High-quality grease should feel smooth and lubricated, with minimal resistance. If you feel grittiness or sand-like particles, it indicates contamination and should be replaced. 2. **Light Inspection Method** On a sunny day, use a screwdriver to pick up a small amount of grease and hold it at a 45-degree angle against the sunlight. Observe the oil droplets. If there are no visible wear particles and the oil flows smoothly, it is still in good condition. If there are many impurities, the grease should be changed. 3. **Filter Paper Test** Place a few drops of grease on a clean white filter paper. After the oil has seeped through, check the residue. If there is black powder or a gritty texture when touched, it means the grease is contaminated. Good quality grease should be dry, smooth, and yellow in color. 4. **Oil Flow Test** Use two measuring cups. Fill one with the lubricant and place the other empty on a table. Lift the filled cup about 30-40 cm above the table and tilt it slowly so the grease flows into the empty cup. High-quality grease should flow smoothly, evenly, and continuously. If the flow is irregular, thick, or inconsistent, the grease may have degraded. --- **Imported Bearings – NSK Bearings Supplier** Maintaining the health of your bearings is crucial for the smooth operation of machinery. Regular inspection and proper lubrication are key to avoiding costly downtime.
