Bearings are used in the process of maintenance and monitoring should be strengthened, and to extend its service life. 1, maintaining a lubrication duct patency, chosen types of lubricants according to regulations, adequate lubrication on a regular basis. Make sure roller rolling surfaces and sliding surfaces of the roller and flanges, maintain good oil wax lubrication. 2, periodically check the seals of seals, replace damaged seals. Ensure that the sealing of the bearing performance in order to prevent the entry of water, iron oxide bearing, preventing the leakage of bearing lubricants. 3, combined with the actual active on bearing health monitor. Noise monitoring: during normal operation should be a smooth hum, regularly monitored and compared with normal sound, timely detection of anomalies. Lubricants monitoring: normal lubricants should be bright and clean, if the lubricant is dirty, abrasive particles or contaminants. Temperature monitoring: at elevated temperatures, running an exception will occur. Our temperature monitoring work has been undertaken, a wider range of services for customers. Establish record cards, records bearing days, steel, electrical and maintenance of online monitoring conditions, strengthen the management of bearing health.
