Henan San Kuang Machinery Technology Co., Ltd., established in 2014 and headquartered in Luoyang, Henan, China, is a professional manufacturer of high-quality slewing bearings. With a factory size of 10,000–30,000 square meters and an annual export value of US$2.5–5 million, we have supplied reliable rotary components to clients across North America, South America, Europe, Southeast Asia, Africa, and Oceania. Our 42CrMo steel slewing bearing with 1.5m outer diameter, single row ball design and 4-point contact configuration delivers outstanding axial load capacity of 500 kN, making it an ideal choice for demanding applications such as cranes, excavators, wind turbines, and robotic systems.
This slewing bearing is engineered to handle combined loads (axial, radial, and moment) with superior precision and durability. The 4-point contact raceway ensures smooth rotation and high rigidity, while the 42CrMo alloy steel provides excellent wear resistance and fatigue strength. Every unit undergoes strict quality control processes, and our certifications (ISO9001, ISO14000, OHSAS18001, SA8000, etc.) guarantee consistent performance and reliability.
