slewing ring

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.

1.Our company produces rotary bearings/turntable bearings with a diameter of 20-10000mm, as well as various high-precision bearings and non-standard mechanical components. We mainly produce large and heavy-duty low-speed heavy-duty bearings, with accuracy covering P0, P6, P5, and p4 levels. The product types include single row four point contact ball structure, cross cylindrical roller structure, three row cylindrical roller structure, double volleyball structure, etc. The products are widely used in new energy, amusement, and other fields Automation, lifting, construction, mining, ports, metallurgy, environmental protection, wind power generation and other fields. 2.Our company has many years of manufacturing and production experience, complete equipment, and a professional technical team. We have cooperated with many new and old customers at home and abroad for many times. We can design and produce according to the required drawings provided by customers to meet customer needs. We also have one-to-one service, please believe us. If you have needs, you can find out first customized product. Customers are welcome to consult.

1.Slewing ring is widely used in construction equipment like excavators. It is wear parts. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. If you need replacements of the steel balls, rollers or spacers, it is also available. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. If you have old slewing bearing in hand, we can instruct you to measure the detailed size to make a professional drawing and then manufacture it for you. 2.Our company has many years of manufacturing and production experience, complete equipment, and a professional technical team.

Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

1.Capable of withstanding various loads, with the highest load-bearing capacity among the four structures 2.The axial and radial dimensions are relatively large, and the structure is sturdy 3.Especially suitable for heavy-duty machinery that requires larger diameters, such as cranes, ladle turntables, and other machinery

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

Single-row crossed roller slewing bearing The single-row crossed roller slewing bearing is composed of two seat rings. It has a compact structure, light weight, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross, which can It can withstand axial force, overturning moment and large radial force at the same time, and is widely used in lifting, transportation and engineering machinery products.

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.
