Ball Slewing Bearing

The slewing bearing of the crane is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time. This product supports customization, and various slewing bearings with special structures can be designed, developed and produced according to user needs.

Turntable bearings, also called slewing bearings, are key components in mechanical equipment. Its features include strong load-bearing capacity, smooth operation and high precision. It mainly consists of an inner ring, an outer ring, rolling elements and a cage. The inner ring and outer ring transmit torque and bear load through rolling elements to realize the rotary motion of the equipment. It is widely used in heavy machinery, wind power, port equipment and other fields. Its excellent performance ensures the efficient and stable operation of the equipment and provides strong support for the development of modern industry.
HGB Company manufactures standard and custom slewing bearings in various designs with outer diameters from 200mm-10000mm to meet the requirements of specific applications.

This large single row ball slewing bearing has become the first choice for many high-end machinery and equipment fields due to its exquisite craftsmanship, excellent performance and exquisite appearance treatment. It is widely used in important industries such as hoisting machinery, port machinery, and wind power generation. Contribute to promoting technological progress and development in related fields.

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.
