  • Swing Bearing For Hyundai

    Excavator is one of the important equipment in modern engineering construction. The reason why the excavator can turn left and right in the work is inseparable from the credit of the slewing mechanism, which is one of the important components of the hydraulic excavator. The slewing mechanism is connected with the traveling device through a slewing bearing, and the slewing drive device makes the platform rotate relative to the traveling device, and drives the working device to rotate around its central axis of rotation. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. Our company has a special quality testing laboratory, devoted to product design and development, product application and testing methods. At the same time, the company also has advanced production equipment and testing equipment to ensure that products have high performance, long life, low friction, high precision.

  • Single Row Four Point Contact Ball Swing Bearing( HS Series)

    Single row four point contact ball slewing ring HS series is a standard model series in China. It is made of inner ring and outer ring. The rolling balls are four point contact with the raceway. It can bear axial force, radial force and overturning moment at the same time. Outer Diameter is from 725mm to 4860mm. It is with non gear type, internal gear type and external gear type.Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc. In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings. This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.
