    Customizable rotary bearings for construction machinery

    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.

  • Crane heavy duty slewing bearing

    Crane heavy duty slewing bearing

    A crane refers to a multi action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Also known as bridge crane, high-altitude crane, or crane. The slewing bearings used in cranes are mainly heavy-duty slewing bearings, which need to withstand large axial forces and overturning moments. The main function is to support the upper mechanism and control its rotation. The electric motor or reducer drives the small gear to rotate, and the small gear drives the slewing support to rotate, causing the upper mechanism connected to it to rotate accordingly.

  • OEM Non Gear Slew Ring for Medical Equipment Gamma Knife

    OEM Non Gear Slew Ring for Medical Equipment Gamma Knife

    Medical equipments do not have high requirements on the load-carrying capacity of the slew ring, so the slew rings generally selected are characterized by lightness and small size. The slew ring selected for medical devices require high precision, including axial and radial clearances and surface precision, to ensure the accuracy of medical devices.
    The product we made has been finely ground to improve the precision, flexible rotation and high precision. It is mostly used in automated production lines, robot arms, bases, and medical machinery with stable quality.

  • Single Row Four Point Contact Ball Slewing Bearing( 01 Series)

    Single Row Four Point Contact Ball Slewing Bearing( 01 Series)

    Single row four point contact ball slewing bearing 01 series is a standard model series in China. It is made of two seat rings. The balls and the raceway are with four points contact, via which the axial force, radial force and resultant moment is born simultaneously. Outer Diameter is from 280mm to 4726mm. Most models slewing ring are with ready stock or semi-finished material stock, which can deliver out within 15 days.
    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.

  • Pitch Bearing Of Wind Turbine Generator

    Pitch Bearing Of Wind Turbine Generator

    The material pitch bearing rings is 42CrMo, the heat treatment adopts the overall quenching and tempering treatment, and the surface of the raceway is quenched. The force of pitch bearings is complex, and the impact and vibration are relatively large. Therefore, the bearing is required to withstand both impact and large load. The life of the wind turbine main engine is required to be 20 years, and the cost of bearing installation is relatively large, so the life of the yaw and pitch bearings is required to reach 20 years. The hardness of the bearing ring base is 240-280HB, which can withstand impact without plastic deformation. At the same time, the surface quenching hardness of the raceway reaches 55-62HRC, which can increase the contact fatigue life and ensure the service life of the bearing.
