Turntable Bearing

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.

The accuracy covers four levels of P0, P6, P5 and P4. Product types include Single row four-point contact ball structure, crossed cylindrical roller structure, three-row cylindrical roller structure, double row ball structure, ball-column combined structure, thin-walled flange structure, large thrust ball structure, etc. Products are widely used in new energy, medical care, amusement, automation, lifting, construction, mining, metallurgy, ports, textiles, ships, environmental protection, aerospace, wind power and other fields. The company's products are sold throughout the country and exported to Europe, America, Asia and other countries and regions, and have been approved and recognized by the majority of users.

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.

Crossed roller slewing bearing is a key component commonly used in construction machinery and lifting equipment. It has the advantages of strong load-bearing capacity, flexible rotation and long service life. Crossed roller slewing bearing, referred to as slewing bearing, is a slewing bearing with rolling elements. Bearing, commonly used in construction machinery and lifting equipment. It realizes return through the rolling of rolling elements Rotating motion, bearing and transmitting loads, while having high stiffness and load-bearing capacity.

Turntable bearing is with features of small friction, high limit speed, simple structure, low cost, easy to achieve high manufacturing precision. The turntable bearing can bear various loads of diameter, shaft and overturning at the same time. It has a firm structure and is especially suitable for heavy-duty machinery with large loads, such as port cranes, molten steel platforms, and shield machines. and other heavy machinery.

The single-row cross-roller slewing bearing consists of two rings, with compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. It can bear overturning moment and large radial force and it is widely used in transportation, construction machinery and military products. There are two basic working modes: 1. The inner ring fixes , and the outer ring rotates; 2. The outer ring fixes and the inner ring rotates. The raceways of the slewing bearing are all treated by surface induction hardening, and the quenching hardness is guaranteed to be HRC55~62, which can achieve sufficient hardened layer depth. Slewing bearing is usually made with internal teeth, external teeth or no teeth. The heat treatment of gears is generally normalized or quenched and tempered. The tooth surface can also be quenched according to the user's requirements, the quenching hardness is HRC50-60, and sufficient depth can be guaranteed. Teeth grinding is also supported.

Slewing bearing is a new type of slewing product, which can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. Construction machinery is the initial application of slewing bearings, and it is also most widely used. 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.
