Ball Slewing Bearing

Ultra-thin black slewing bearing is a high-quality product that combines lightweight, high strength and anti-rust properties. It is manufactured using advanced precision processing technology to ensure ultra-high precision and stability of the product. The surface has been specially blackened, which not only increases the wear resistance, but also makes the product have good anti-rust effect.

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.

Our company can design, customize and produce according to customer needs. As a clean and renewable energy source, wind power has been widely used around the world. In wind turbines, slewing bearings are used to support the wind wheel and enable it to rotate with changes in wind direction, thereby maximizing the capture of wind energy and improving power generation efficiency.

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.

1.Easy to assemble, able to withstand large axial forces and overturning moments
2.Customizable structure, tight structure, special design of raceway
3.Suitable for loading and unloading machinery with a diameter of medium or above

The single-row four-point contact ball slewing bearing is composed of two seat rings. It has a compact structure and light weight. The steel balls are in four-point contact with the arc raceway and can withstand axial force, radial force and overturning moment at the same time. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators can all be used.

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.

1. The work is simple and sensitive, and the rotation resistance is small.
2. The structure is compact and the dimensions (mainly height) are small.
3. Convenient maintenance and long service life.
4. It is composed of ring gear, seal and screws, etc. It is easy to install and convenient for specialized centralized production.
5. There is no intermediate pivot, and other components can be installed in the middle space.

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.
