Choosing a Ball Bearing Slewing Ring

Using a ball bearing slewing ring is an excellent way to ensure that the shafts in your machinery stay aligned and work smoothly. This is because they work by ensuring that the shafts stay aligned with the slewing ring, which in turn ensures that the bearings are kept in good condition and can work properly.

Lubrication of a slewing ring

Choosing a lubricant for a ball bearing slewing ring depends on the application. There are many different types of lubricants available. It is important to find out which one is right for your application.

Lubricants should be selected based on the application and load. A lubricant with a high base oil viscosity (> 500 c/s at 40C) is ideal. Shock loads should be avoided to minimize damage to the raceways.

In some cases, a central lubrication system can be installed to make lubrication easier. Slewing ring bearings are generally used for applications with high-torque and radial loads.

Slewing rings have several unique characteristics. They are heavy-duty and highly lubricated. They have seals on both the upper and lower halves of the bearings. These seals protect the bearing from contamination.

Slewing ring bearings can be found in a variety of different sizes. Larger bearings are more prone to premature failure. For this reason, a large diameter bearing should be avoided.

Applications for a slewing ring

Whether you are in the construction industry, the military, or general mechanical engineering, slewing ring bearings offer unique benefits. They are ideal for supporting axial, radial, or moment loads. They are also used in gear drives, robotics, and lifts. They can be driven by an external gear or a drive-plate coupling.

The materials used for slewing rings vary according to the application. They can be made from plastic or steel. Generally, plastic slewing rings have larger surface areas, which allows them to handle heavier loads. They are also available with rectangular cross sections to improve stiffness.

These slewing rings are available in a range of sizes, from a few inches to over three meters in diameter. Most are manufactured from 42CrMo4 steel, although other materials may be used for special functional requirements. Normally, they are installed horizontally on a wooden pallet.

Slewing rings are typically used in slow applications, where a large load requires a heavy bearing. When the load exceeds the capacity of the bearing, the load will cause permanent deformation. For this reason, a slewing ring must have a high degree of reliability.

Series 5000 Cross Roller vs Series 6000

Whether you are choosing between the Series 5000 Cross Roller vs Series 6000 ball bearing slewing ring, you should take into account the design and functionality of each. Both are large diameter antifriction bearings designed for axial and tilting forces. They are available in various designs and sizes, with the majority of slewing rings being custom-designed to meet specific functional requirements.

The Series 5000 Cross Roller features two roller paths in each ring, which allows for a larger radial capacity. The roller raceways are precision machined from alloyed quenched and tempered steel. The rolling elements are guided by spacers and are sealed with a grease lubrication system.

The Series 6000 ball bearing slewing rings are designed for high speeds and provide an extended radial capacity. They are manufactured with V-groove style raceways, which allow for two roller paths in each ring. The rolling elements are lubricated with lithium-saponified EP multi-purpose greases, which are ideal for a variety of applications.

Series 7100 Vertical Thrust

Typically, vertical motors use thrust bearings to support the loads. Thrust bearings can be of several types, including ball, roller, or hydrodynamic bearings. They can support the load in a wide range of situations, and may include a gear or gearbox, depending on the application.

The type of bearing that is appropriate for your application will depend on the type of load that is being supported. Ball bearings are ideal for applications where the load is predominantly in the circumferential direction, while roller bearings are more suitable for applications where the load is predominantly in the axial direction. Some applications will also require an additional guide bearing, which is used to support momentary thrust loads.

For applications with low rotational torque, a slewing ring may be the most suitable choice. A slewing ring has two concentric rings, which form a sphere when a load is placed on the outer ring. This design improves power transmission and load support.
