      Three Roller Rotary Bearings
             Three rows of roller slewing support have three seat rings. The upper and lower raceways and the radial raceways are separated, so that the load of each row of roller can be determined accurately. Being able to bear all kinds of loads at the same time, it is one of the largest load-carrying capacity of the four products. Its axle and radial dimensions are large and its structure is firm. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel excavator, wheel crane, marine crane, port crane, molten steel platform and large tonnage truck crane. Wait for machinery.
      Periodic Inspection and Maintenance of Slewing Bearing
             For the first time, 100 working hours of slewing support are used to check the bolt pre-tightening moment. If more than 10% of the bolts are loose, check again in 200 working hours. Check every 500 working hours in the future; shorten the check interval in bad working conditions.
             If a bolt is found to be loosened below 80% of the specified moment after 2000 hours of work, the bolt and two adjacent bolts should be replaced. If it is found that 20% of the bolts are loosened to less than 80% of the specified moment, all the bolts should be replaced.
             After 14,000 hours of work, all bolts will be replaced. For equipment with high rotation speed or continuous rotation or frequent operation, refuel every 100 working hours. The time interval of adding lubricating grease should be further shortened in bad working conditions.
