Types of Slewing Bearings

Slewing bearings are large-sized bearings that are specifically designed to accommodate oscillating movements. They are comprised of an inner ring and an outer ring, one of which usually incorporates a gear. The bearing raceways, in conjunction with the rolling elements, allow for the rotation of the slewing bearing.

There are four main types of slewing bearings: single-row ball type, double-row ball type, crossed roller type, and three-row roller type. Each type of slewing bearing has its own unique characteristics and is best suited for different applications.

Single-Row Ball Type

Single-row ball type slewing bearings consist of a single row of balls between two raceways. These bearings are able to handle axial, radial, and moment loads in any direction. Single-row ball type slewing bearings are commonly used in light to medium-duty applications, such as cranes, excavators, and small wind turbines.

Double-Row Ball Type

Double-row ball type slewing bearings consist of two rows of balls between two raceways. These bearings are able to handle higher axial and radial loads than single-row ball type slewing bearings. Double-row ball type slewing bearings are commonly used in medium to heavy-duty applications, such as excavators, tower cranes, and tunnel boring machines.

Crossed Roller Type

Crossed roller type slewing bearings consist of rollers that are crossed at right angles between two raceways. These bearings are able to handle high axial and radial loads, as well as moment loads in any direction. Crossed roller type slewing bearings are commonly used in heavy-duty applications, such as cranes, excavators, and robots.

Three-Row Roller Type

Three-row roller type slewing bearings consist of three rows of rollers between two raceways. These bearings are able to handle extremely high axial and radial loads, as well as moment loads in any direction. Three-row roller type slewing bearings are commonly used in heavy-duty applications, such as cranes, excavators, and wind turbines.

In summary, each type of slewing bearing has its own unique characteristics and is best suited for different applications. Single-row ball type slewing bearings are commonly used in light to medium-duty applications, while double-row ball type slewing bearings are commonly used in medium to heavy-duty applications. Crossed roller type slewing bearings are commonly used in heavy-duty applications, while three-row roller type slewing bearings are used in extremely heavy-duty applications.

Applications of Slewing Bearings

Slewing bearings are used in a variety of industries due to their ability to support heavy loads and accommodate oscillating movements. Here are some of the most common applications of slewing bearings:

Construction Machinery

Slewing bearings are widely used in construction machinery such as cranes, excavators, and concrete pumps. These machines require large bearings that can handle heavy loads and withstand harsh environments. Slewing bearings are ideal for these applications because they can support axial, radial, and moment loads, and they have a long service life.

Medical Equipment

Slewing bearings are also used in medical equipment such as CT scanners and X-ray machines. These machines require precise movement and positioning, and slewing bearings provide the necessary support. Slewing bearings used in medical equipment are typically smaller and more precise than those used in construction machinery.

Renewable Energy

Slewing bearings are also used in renewable energy applications such as wind turbines and solar tracking systems. Wind turbines require large bearings that can handle heavy loads and withstand harsh environments. Slewing bearings used in wind turbines are typically larger than those used in construction machinery. Solar tracking systems require precise movement and positioning, and slewing bearings provide the necessary support.

In conclusion, slewing bearings are versatile components that are used in a wide range of applications. Whether you are building construction machinery, medical equipment, or renewable energy systems, slewing bearings can provide the necessary support and durability.

Selection Criteria for Slewing Bearings

When selecting a slewing bearing, there are several criteria that you need to consider. In this section, we will discuss the load capacity, gear requirements, and mounting configuration that you should keep in mind.

Load Capacity

The load capacity of a slewing bearing is one of the most important criteria to consider. You need to ensure that the bearing can handle the weight and forces that will be applied to it. To determine the load capacity that you need, you should consider the maximum load that the bearing will be subjected to, as well as any shock loads or vibrations that may occur.

Gear Requirements

The gear requirements for your slewing bearing will depend on the application. You need to consider the speed and torque requirements, as well as the direction of rotation. You may also need to consider the type of gear teeth, such as helical or straight.

Mounting Configuration

The mounting configuration is another important factor to consider. You need to ensure that the bearing can be mounted in the correct position and orientation for your application. You should also consider the space available for mounting, as well as any other components that may need to be mounted on the bearing.

To summarize, when selecting a slewing bearing, you need to consider the load capacity, gear requirements, and mounting configuration. By carefully considering these criteria, you can ensure that you choose a bearing that will meet the needs of your application.

Maintenance and Servicing

Proper maintenance and servicing of slewing bearings are crucial to ensure their longevity and optimal performance. In this section, we will discuss some of the best practices for maintaining and servicing your slewing bearings.

Lubrication Practices

Lubrication is one of the most important aspects of slewing bearing maintenance. Proper lubrication can significantly extend the life of the bearing and reduce the risk of premature failure. It is recommended to use a high-quality lubricant that is compatible with the bearing’s material and operating conditions. You should also follow the manufacturer’s recommendations for lubrication frequency and quantity.

Regular Inspection

Regular inspection of the slewing bearings is essential to detect any signs of wear, damage, or other issues. You should inspect the bearings at least once a year, or more frequently if they are exposed to harsh operating conditions. During the inspection, you should check for any signs of corrosion, cracks, or deformation. You should also check the gear teeth for any signs of wear or damage.

Replacement Procedures

If the slewing bearings are damaged beyond repair, they will need to be replaced. Replacement procedures can vary depending on the type of bearing and the equipment it is installed on. It is recommended to follow the manufacturer’s instructions for replacement procedures to ensure proper installation and optimal performance.

In summary, proper maintenance and servicing are crucial for the optimal performance and longevity of slewing bearings. By following the recommended lubrication practices, conducting regular inspections, and following proper replacement procedures, you can ensure that your slewing bearings will provide reliable and efficient operation for many years to come.

Choosing a Distributor

Look for distributors that are ISO 9001 certified, as this ensures that they have a quality management system in place. Additionally, some distributors may have industry-specific certifications, such as AS9100 for aerospace or ISO/TS 16949 for automotive. These certifications demonstrate that the distributor has a commitment to quality and can provide you with high-quality products.

Product Range

Another important factor to consider is the distributor’s product range. You want to choose a distributor that offers a wide variety of slewing bearings, including different sizes, materials, and configurations. This will ensure that you can find the right bearing for your application. Additionally, look for distributors that offer custom solutions, as this can be helpful if you have unique requirements.

Customer Service

Customer service is also an important consideration when choosing a slewing bearing distributor.
