Professional Slewing Bearing Manufacturer

Professional Slewing Bearing Manufacturer

LTZC Bearing provides customers with high-quality slewing bearings in various sizes for a variety of applications. Sizes range from 3 inches (100 mm) to 6 feet (2 meters) outside diameter. For design and application purposes, slewing bearings are available with external teeth on the outer ring, internal teeth on the inner ring, or without teeth.

Drive pinions and hydraulic motors can be meshed with appropriate slewing bearings as required. Single-row and double-row slewing bearings are available to accommodate different load applications. For non-market standard slewing bearings, our team of engineers works with customers to provide customized slewing bearings based on the required performance.

What is Slewing Bearing ？

A slewing bearing, also known as a slewing ring, turntable bearing, or rotary bearing, is a large, heavy-duty bearing that is designed to support oscillating movements, rotation, radial and axial loads, or a combination of those forces. They are commonly used in heavy machinery and equipment where smooth and precise rotation is required, such as cranes, excavators, wind turbines, radar systems, and robotic arms.Slewing bearings typically consist of two concentric rings or races with grooves on the inner and outer surfaces. Rolling elements such as balls or cylindrical rollers fill these grooves, enabling relative motion between the two rings.

Benefits of Using Slewing Bearings：

Slewing bearings are an essential component in large, heavy-duty machinery used in various industries such as construction, wind turbines, military, and material handling equipment. They play a critical role in managing loads and facilitating smooth and precise rotation. The benefits of using slewing ring bearings include the following:

1. High Load Capacity: Slewing bearings are designed to support heavy axial and radial loads as well as bearing moment loads, allowing for larger, more complex machinery to be built.

2. Versatility: These bearings can be used in a wide range of applications such as cranes, excavators, wind turbines, medical equipment, and access platforms, making them a staple for many diverse industries.

3. Compact Design: With an integrated, compact structure, slewing ring bearings take up less space compared to other solutions, providing more room for other components in a machine.

4. Ease of Installation: Slewing bearings typically come with pre-drilled holes or attachments, allowing for easier installation and saving time and effort during assembly.

5. Precision and Control: Slewing operational efficiency in machines.

6. Low Maintenance: These bearings have a robust and rugged design that can endure harsh operating environments, and they often require minimal maintenance, lowering the overall cost of operation.

7. Customization: Many manufacturers offer customization to meet specific application requirements, such as different materials, coatings, and gear options.

8. Long Service Life: Slewing bearings are made from high-quality materials and are designed with durability in mind, resulting in a long service life and reduced downtime for equipment.

9. Reduced Friction: Slewing bearings are designed to reduce friction between moving parts, increasing the efficiency of rotation and decreasing wear on the bearing.

10. Environmentally Friendly: These bearings can be manufactured with environmentally friendly materials and lubricants, leading to reduced environmental impact.

In conclusion, slewing bearings offer a variety of benefits, making them an ideal choice for numerous industries and applications. Their high load capacity, compact design, and versatility contribute to increased efficiency and reliability in the machines they support.

Our Slewing Bearing Product：

Four point contact ball slewing bearing:Four point contact ball slewing bearings are a type of slewing ring bearings designed specifically for heavy-load applications requiring smooth and precise rotation. They consist of an inner ring, an outer ring, and a row of balls contained within a raceway that follows a gothic arch, creating four points of contact between the balls and the raceway at any given time. 

Cross Cylindrical Roller Slewing Bearing:Cross cylindrical roller slewing bearings are a type of slewing ring bearing that employs cylindrical rollers in a crossed arrangement to evenly distribute loads and provide smooth rotation. These bearings are designed to support heavy loads and minimize friction, making them ideal for a variety of large industrial machinery and applications. 

Double Row Ball Slewing Bearings:Double row ball slewing bearings, also known as two-row ball slewing bearings, are a type of slewing ring bearing designed for applications requiring heavy load capacity, precision, and high rigidity. They are commonly used in heavy machinery, such as cranes, marine applications, excavators, and wind turbines.

Three Row Cylindrical Roller Slewing Bearing:Three Row Cylindrical Roller Slewing Bearings, also commonly referred to as triple row roller bearings, are a type of slewing bearings designed to manage exceptionally high loads and provide a robust solution for high-performance rotating applications. These bearings efficiently handle axial, radial, and moment loads, making them suitable for heavy-duty machinery.
