Bucket Wheel Excavator Bearing

 

Types of Three Row Combined Roller Slewing Bearing

Bucket Wheel Excavator Bearing
Bucket Wheel Excavator Bearing is a bearing specially designed for large bucket wheel excavator. The bearing adopts a special structural design to meet the working requirements of the bucket wheel excavator under high load and harsh working conditions.

 

Large Tonnage Truck Crane Bearing
Large Tonnage Truck Crane Bearing is a special bearing used on large tonnage truck cranes. This kind of bearing needs to withstand huge loads, including radial force and axial force brought about by horizontal movement, vertical movement and rotational movement.

 

Marine Crane Bearing
Marine Crane Bearing is a special bearing designed and applied for marine cranes. Due to the harsh operating environment of marine cranes, the requirements for bearings are higher, and its reliability and performance have an important impact on the safety and work efficiency of marine cranes.

Features of Three Row Combined Roller Slewing Bearing
 
 

Carrying capacity

Bucket wheel excavator bearings have extremely high carrying capacity and can withstand large torque and heavy loads from the bucket wheel, ensuring the stability and reliability of the excavator during operation.

 
 
 

Durability

Since bucket wheel excavators often operate in harsh working environments, such as high temperature, high humidity, heavy dust, etc., the bearing needs to have good durability and corrosion resistance to ensure long-term reliable work.

 
 
 

Lubrication method

Bucket wheel excavator bearings usually need to be lubricated with grease or lubricating oil, so as to reduce rolling friction and wear, and improve bearing life and performance.

Marine Crane Bearing

 

Usage of Three Row Combined Roller Slewing Bearing
 

Construction site: Large-tonnage truck cranes are often used for lifting and transportation tasks on construction sites. Bearings carry the crane's load arm, slewing mechanism, jib and other components, and ensure the stable operation and load transmission of the crane.

 

Ports and ships: Large-tonnage truck cranes can be used for port loading and unloading and ship operations. Ship-mounted cranes usually require large bearings to support the crane's rotation and hoisting functions, and to withstand various forces and vibrations brought about by the ship's motion.

 

Large-scale industrial projects: Large-tonnage truck cranes are widely used in large-scale industrial projects, such as mining, steel smelting, and energy construction. They are used to transport and hoist large equipment and heavy objects, and the bearings provide the necessary support and transmission functions for the crane.

FAQ

 

Q: What are the structural characteristics of three row combined roller slewing bearings?

A: Three row combined roller slewing bearings have three raceways, namely the upper, middle, and lower raceways. This structure enables the bearing to accurately determine the load on each row of rollers and simultaneously bear various loads, including axial force, radial force, and overturning moment. It has a large load - bearing capacity and is structurally firm.

Q: In which applications are three row combined roller slewing bearings commonly used?

A: They are widely used in heavy - duty machinery that requires large - diameter bearings and has high load - bearing requirements, such as bucket - wheel excavators, wheel - mounted cranes, marine cranes, port cranes, ladle turntables, and large - tonnage truck cranes.
They are also used in some large - scale construction machinery and equipment, such as tower cranes and concrete pump trucks, to provide reliable support and rotation function.

Q: How to select the appropriate three row combined roller slewing bearing?

A: Consider the installation space and select a bearing with appropriate dimensions. Consider factors such as rotation speed, working environment, and sealing requirements to ensure the normal operation and service life of the bearing.

Q: How to ensure the proper installation of three row combined roller slewing bearings?

A: Before installation, check the dimensions and accuracy of the installation parts to ensure they meet the requirements.
During installation, use appropriate tools and follow the installation instructions to ensure that the bearing is installed correctly and evenly.

Q: What kind of lubrication is suitable for three row combined roller slewing bearings?

A: Grease has good sealing performance and can prevent the ingress of contaminants, which is suitable for applications where maintenance is not frequent. Oil lubrication has better heat dissipation and cooling effects, which is suitable for high - speed and high - temperature applications.

Q: How to maintain three row combined roller slewing bearings?

A: Regularly check the bearing for wear, damage, and lubrication conditions.
Clean the bearing surface and the surrounding area to prevent the ingress of dust, dirt, and moisture.
Check the tightness of the installation bolts and nuts to ensure the bearing is securely installed.
