Analysis of the inspection items after the bearing works

After completing the installation of a bearing, it is essential to conduct a thorough inspection to ensure everything is functioning correctly. For smaller machinery, you can manually rotate the unit to check if the rotation is smooth and free of resistance. During this process, inspect for any foreign objects, scratches, or dents that could affect performance. Also, check for unstable torque caused by issues like excessive clearance, equipment misalignment, or seal interference. If no abnormalities are found, the machine can be powered on. For larger machinery, manual rotation is not feasible, so the power should be disconnected immediately after a no-load start. Allow the machine to idle and observe for any vibrations, unusual noises, or contact between rotating parts. Once everything appears normal, proceed with the power operation. During the power work phase, start with no-load and low-speed operation, gradually increasing to full load under specified conditions. Monitor key factors such as abnormal sounds, changes in bearing temperature, leakage, or discoloration of lubricants. It’s important to visually inspect the machine regularly, and if necessary, remove the bearing for a closer look. Bearing temperature is typically estimated based on the external temperature of the housing, but for more accurate readings, use a thermometer to measure the outer ring directly. The temperature should gradually rise during initial operation and stabilize within 1–2 hours. A sudden spike in temperature may indicate problems such as excessive lubricant, too small clearance, poor alignment, or seal friction. High-speed operation can also lead to overheating due to improper bearing selection or layout. Unusual sounds from the bearing can be identified using a stethoscope. Listen for loud metallic noises, irregular sounds, or abnormal patterns that may signal issues such as poor lubrication, misaligned shafts, damaged bearings, or the presence of foreign particles. In addition to these checks, maintaining proper lubrication, ensuring correct installation, and following manufacturer guidelines are crucial for the long-term performance of bearings. Regular maintenance and inspections can prevent unexpected failures and extend the life of the equipment. For more information on bearings and related topics, visit China Bearing Network.
