Vier-Punkt-Kontakt-Kugeldrehkranzlager

Four Point Contact Ball Slewing Bearings are the core components of heavy machinery slewing systems and are designed to cope with complex load conditions. Its structure is composed of inner ring, outer ring, integral raceway and single row of steel balls. It adopts unique “Gothic” raceway design and contact angle optimization, so that it can bear extremely high axial force, radial force and tilting moment at the same time with a compact single row structure. The product represents the industry’s top manufacturing standards, with excellent static load capacity and structural rigidity, while ensuring high reliability and operating accuracy, the perfect balance of space occupation and load-bearing performance. In terms of application benefits, the design significantly simplifies the host structure, and significantly reduces the weight and procurement cost of the equipment compared to the traditional multi-row bearing combination. The product provides a variety of configurations such as internal teeth, external teeth and toothless, supports customization of high-strength materials such as 42CrMo, and has the advantages of convenient installation, long lubrication and maintenance cycle and strong environmental adaptability. It is widely used in lifting conveyors, excavators, wind power generation and automation equipment, even in harsh conditions can maintain long-term stable operation, to provide customers with highly cost-effective and efficient transmission solutions.
