How can we increase the service life of the four point contact ball slewing bearing?

A well-designed slewing bearing can greatly increase the service life of the four point contact ball slewing bearing, as long as it is properly operated and used, whether it is installation, use or subsequent maintenance.

Installation of four point contact ball slewing bearing：

Regarding the installation of the four point contact ball slewing bearing, first of all, the stop should be in place, the installation holes should be aligned, and the bolts should be pre-tightened first, and then tightened according to the diagonal method with reference to the tightening torque of different bolts.

In fact, there are two main points to pay attention to the installation of the slewing bearing, the first is the installation platform, and the second is the installation method.

The installation platform of the four point contact ball slewing bearing must first have sufficient strength support, and secondly, it must have sufficient flatness. Many people have no problem with the strength of the bearing, but often ignore the flatness of the installation surface.

The general accuracy of the slewing bearing produced by Fuji Transmission Higher, the requirements for the flatness of the mounting surface are also higher.

If the flatness of the mounting surface is greater than the parallelism of the four point contact ball slewing bearing, when the bolts are tightened, the accuracy of the slewing bearing will be lost, and the slewing bearing will be deformed, and the grooves will be deformed.

The dislocation of the slewing bearing reduces the service life of the slewing bearing, and the installation platform of the slewing bearing is generally machined.

When installing the slewing bearing, check the flatness. For defective positions, you can use the method of adding gaskets. The bonding surface of the slewing bearing and the installation platform should be clean and free of particles and other debris.

The slewing bearing has the position of the soft belt when it leaves the factory, which is generally marked as S. The plug is always the position of the soft belt. When installing the slewing bearing, special attention should be paid to the position of the soft belt. The position of the soft belt should be adjusted to the non-load area or not often.

In the load area, the soft belt area of ​​the inner ring and the outer ring of the four point contact ball slewing bearing should be staggered by 180°. When installing slewing bearings on some lifting equipment such as truck cranes, cranes and tower cranes, the position of the soft belt should be installed at 90° to the boom.

Use and maintenance of four point contact ball slewing bearing:

In the use of the slewing bearing, be sure to refer to the installation manual and maintenance manual issued by the manufacturer for guidance. The sealing strips, rolling elements, and grease should be replaced in time according to different working conditions.

The slewing bearing is filled with 70% grease in the channel when it leaves the factory, which can be used by users for a period of time. When adding grease again, pay attention to cleaning up the residual grease and fill it with the grease brand and model recommended by the manufacturer. , Note that the grease must not be mixed, and the grease of the same brand and model is the best.

For slewing bearings with teeth, the grease on the teeth should be replaced and cleaned in time to ensure that the tooth surfaces are clean and free of particles and other debris, so as to avoid damage to the tooth surfaces when the teeth mesh for a long time.

When replacing the slewing bearing rolling element, retainer, and sealing, the four point contact ball slewing bearing needs to be disassembled and assembled.

When the slewing bearing is placed, it must be lifted and stored horizontally, and vertical lifting and storage are prohibited. During use, pay attention to the operation of the slewing bearing. If noise, impact, jitter, and shaking are found, the operation should be stopped in time, the fault should be eliminated, and the manufacturer should be contacted to provide technical support if necessary.

The installation of the slewing bearing is very important. The correct installation method can greatly increase the life of the slewing bearing and make the later maintenance and maintenance more convenient and labor-saving. Regular maintenance of the slewing bearing, replacement of wearing parts, protection of the channel, and protection of the tooth surface can also effectively extend the life of the slewing bearing.
