Reasonable selection of linear bearing replacement time. Using the regular maintenance time during the middle shift every day, the linear bearing is removed for inspection and maintenance, and the removed linear bearing is cleaned, inspected, lubricated and maintained, and then used as a spare part replacement.

Strengthen sanitation and maintenance, include the guide rail of the turner in the daily insurance, and there should be no grease on the surface of the guide rail, so as to prevent oil from entering the interior of the linear bearing, reduce the running resistance of the linear NTN bearing both up and down, and improve the linear bearing, ball nut and linear bearing. The service life of the screw screw reduces the maintenance intensity. Before the retrofit of the linear bearing, an average of one was replaced every month, and several ball nuts and screw screws were replaced every year, causing downtime. After the transformation, the service life of the linear bearing has been extended by about half a year. On average, more than ten linear bearings and multiple ball nuts and screw screws can be saved every year, which saves a lot of costs for the maintenance and replacement of spare parts. At the same time, the equipment is effective. The improvement of the operation rate and the rational allocation of human resources in three shifts in the workshop create higher value for the enterprise.
