The gear processing takes place on the outer circumference of the outer ring, which functions as both the bearing ring and the driving gear ring. By engaging the driving small gear with the outer teeth of the outer ring, efficient rotational power transmission is achieved. When the small gear turns, it drives the outer ring to rotate, while the inner ring remains fixed to the base or frame. This unique design allows the outer ring to drive the connected upper structure, such as an excavator's upper frame, to also rotate smoothly, Our products feature steel balls that provide a four-point contact with the inner and outer ring raceways, enabling them to handle axial loads, radial loads, and overturning moments simultaneously. This capability meets the demands of various combined force conditions effectively. With a compact structure, composite load-bearing, and active transmission characteristics, our gear system is ideal for medium and light equipment power rotation requirements, As a leading manufacturer in China, we take pride in being one of the top suppliers and factories in the industry, ensuring high-quality and reliable gear solutions for your operational needs
