Rolling mill bearing maintenance

Bearings should be maintained and monitored during use to prolong their service life.
1. Keep the lubricating oil passage unobstructed, select the type of lubricant according to the regulations, and fill the lubricant regularly and in sufficient quantities. Ensure that the rolling surfaces of the rollers and the sliding surfaces of the rollers and ribs are well lubricated with oil and wax.
2. Regularly check the sealing condition of the seals, and replace damaged seals in time. Ensure the sealing performance of the bearing to prevent water and iron scale from entering the bearing and prevent the leakage of bearing lubricant.
3. In combination with the actual situation of the enterprise, actively carry out the monitoring of the operation status of the bearings.
Noise monitoring: There should be a steady humming sound during normal operation, and it should be monitored regularly and compared with the normal sound to detect abnormalities in time.
Lubricant monitoring: normal lubricant should be clear and clean, if the lubricant has become dirty, there will be wear particles or pollutants.
Temperature monitoring: When the temperature rises, the operation will appear abnormal. The company has carried out temperature monitoring work and is willing to serve customers more extensively.
Establish a record card to record the number of days the bearing is used online, the amount of steel passing through and the maintenance monitoring status, etc., to strengthen the management of the bearing operation status.
