This gear processing technology is focused on the outer circumference of the outer ring, which functions as both a bearing ring and a driving gear ring. The driving small gear engages with the outer teeth of the outer ring, effectively transmitting rotational power. As the small gear rotates, it causes the outer ring to spin, while the inner ring remains fixed to the base (frame). This design allows the outer ring to drive the upper structure it is attached to, such as the upper frame of an excavator. Our steel balls exhibit a four-point contact with both the inner and outer ring raceways, enabling them to manage axial loads, radial loads, and overturning moments simultaneously, thereby accommodating combined force conditions efficiently. This product showcases a compact structure, composite load-bearing capabilities, and active transmission features, making it an ideal choice for medium and light equipment power rotation needs. As a leading manufacturer in China, we take pride in providing top-quality products directly from our factory, ensuring you get the best solutions for your machinery from reliable suppliers.
