The integral forging eliminates the stress concentration points 1 the weld, improves the fatigue resistance of the product under alternating load by more than 40%, and completely avoids the hidden danger of weld cracking after long-term use. In the heat treatment process, we implemented the full raceway scanning quenching and tempering treatment to ensure the uniformity of the hardened layer and the stability of the metallographic structure. Compared with the common \u201cjump\u201d quenching of similar products, our process eliminates the soft spot area on the raceway surface, making the ball or roller wear evenly during operation, and avoiding the sticking phenomenon caused by local peeling."],"comparison_points_description1":["In view of the tooth breakage problem that is easy to occur when large excavators and stacker-reclaimers start at high torque, we have carried out shot peening treatment on the tooth root, and adopted surface quenching process on the tooth surface, so that the bending fatigue strength of the tooth root is increased by 30%, and the instantaneous impact load is effectively resisted."],"comparison_points_description2":["In view of the high salt spray corrosion pain points faced by offshore cranes and port machinery, we sprayed zinc-rich anti-corrosion coating with a thickness of 150 microns on the sealing groove and non-matching surface, and cooperated with multi-layer labyrinth sealing, which successfully solved the problems of raceway rust and cage fracture caused by salt spray erosion."],"comparison_points_description3":["In view of the problems of rotary shaking and inaccurate positioning of large-diameter equipment after several years of operation, we have eliminated the trace clearance inside the bearing before leaving the factory through the negative clearance pre-tightening assembly technology, which greatly improves the rigidity of the system and solves the problem of unstable operation of the equipment caused by excessive clearance."],"application_title":["Large Slewing Bearing Applicable Crowd"],"application_title1":["Port Crane and Quayside Equipment Maintainer"],"application_title2":["Tunnel Boring Machine Manufacturer"],"application_title3":["Wind turbine operation and maintenance team"],"application_title4":["Open pit mine machinery purchasing manager"],"application_describe1":["It is suitable for slewing mechanism of port portal crane and quayside container crane (quayside bridge).
