The 4.4-meter stacker-reclaimer slewing bearing has successfully passed acceptance inspection

Luoyang,China,29 August 2025：Recently, two sets of 4.4-meter coal yard stacker-reclaimers equipped with four-point contact ball slewing bearings successfully passed acceptance by a Middle Eastern customer. This marks another milestone for LZJM's ultra-large slewing bearings in overseas markets.

In the field of ultra-large bearing machining, equipment capabilities often serve as the core factor determining a company's competitiveness. LZJM has successfully established itself as a dual benchmark for both technology and production capacity within the industry through its 8-meter double-column CNC vertical lathe. This high-end equipment not only delivers exceptional precision machining capabilities but also breaks through the dimensional constraints of traditional processing. It can reliably manufacture ultra-large bearings with diameters up to 10 meters, providing critical solutions for numerous industries with stringent requirements for bearing size and precision.

Based on this core processing capability, LZJM's ultra-large bearing products have successfully established a foothold in multiple key industrial sectors, becoming a trusted partner for numerous enterprises. In the material handling and processing field, whether for port cargo handling stacker-reclaimers, coal yard stacker-reclaimers ensuring energy supply, or mining stacker-reclaimers serving mineral development, LZJM bearings can bear high-intensity, high-load operating environments. They ensure continuous and stable equipment operation, effectively reducing downtime risks and maintenance costs.In the fields of lifting and precision manufacturing, port cranes demand extremely high load-bearing capacity and rotational precision from bearings. LZJM products, with their outstanding structural stability and precision control, empower cranes to efficiently complete heavy-load hoisting operations. In the precision machine tool field, where accuracy requirements are even more stringent, these bearings provide strong assurance for machining precision through their ultra-low error and high resistance to wear. Furthermore, in the complex marine communication and control field, LZJM bearings have excellent corrosion resistance and poor environment resistance, adapting to the special operating conditions of high humidity and high salt fog in the marine environment to ensure the stable operation of communication and control equipment.

From energy and mining to ports and manufacturing, extending to marine engineering, LZJM takes its 8-meter double-column CNC vertical lathe as the foundation. With high-quality ultra-large bearing products, it continuously powers the high-quality development of various industries, strengthening its leading position in the ultra-large bearing field.
