Types and Variations
If you are looking for a reliable and efficient way to support heavy loads and rotation, ball bearing slewing rings are a great option. These rings come in different types and variations depending on the load capacity, speed, and other factors. In this section, we will cover the three main types of ball bearing slewing rings: single-row, double-row, and crossed roller rings.
Single-Row Ball Bearing Slewing Rings
Single-row ball bearing slewing rings are the most common type of slewing rings. They have a single row of balls and a standard bearing raceway. They offer four points of contact between the balls and the raceway, which allows them to handle both axial and radial loads. Single-row rings are suitable for applications that require moderate load capacity and low-speed rotation. They are also relatively easy to install and maintain.
Double-Row Ball Bearing Slewing Rings
Double-row ball bearing slewing rings have two rows of balls and two raceways, which provide eight points of contact for each ball. This design allows them to handle higher loads and faster rotation speeds than single-row rings. Double-row rings are suitable for applications that require high load capacity and moderate to high-speed rotation. They are commonly used in cranes, excavators, and other heavy-duty equipment.
Crossed Roller Slewing Rings
Crossed roller slewing rings have a different design than ball bearing rings. They use rollers instead of balls, which allows them to handle higher loads and provide more precise rotation. Crossed roller rings have a crossed arrangement of rollers that provides two points of contact for each roller. This design allows them to handle both axial and radial loads and provide smooth and accurate rotation. Crossed roller rings are suitable for applications that require high precision, such as machine tools, robotics, and medical equipment.
In summary, ball bearing slewing rings come in different types and variations that can handle different loads, speeds, and precision requirements. Choosing the right type of slewing ring depends on your specific application needs.

When it comes to ball bearing slewing ring, performance and testing are crucial factors that determine their suitability for various applications. Here are some key aspects of performance and testing that you should be aware of:
Load Capacity Testing
Load capacity testing is a critical aspect of ball bearing slewing ring performance. The load capacity of a slewing ring refers to the maximum load that it can support without failure. This value is typically determined by testing the slewing ring under different loads and measuring the resulting deformation.
During load capacity testing, the slewing ring is subjected to a range of loads and stresses that simulate real-world operating conditions. This testing is typically conducted in a laboratory setting, using specialized equipment and software that can accurately measure the load and deformation of the slewing ring.
Lifecycle and Reliability
Lifecycle and reliability testing are also important aspects of ball bearing slewing ring performance. These tests are designed to evaluate the durability and longevity of the slewing ring under different operating conditions.
During lifecycle testing, the slewing ring is subjected to a range of loads and stresses that simulate the expected lifespan of the product. This testing is typically conducted over an extended period of time, during which the slewing ring is monitored for signs of wear and tear.
Reliability testing, on the other hand, is focused on evaluating the probability of failure of the slewing ring under different conditions. This testing is typically conducted using statistical methods that take into account the expected lifespan of the product, as well as the likelihood of different types of failure.
In conclusion, load capacity testing, lifecycle testing, and reliability testing are all important aspects of ball bearing slewing ring performance. By understanding these factors, you can make informed decisions about which slewing rings are best suited for your specific applications.
