As an important transmission component in construction, the slewing bearing provides strong support for the rotation and positioning of various heavy equipment and structures with its unique structure and excellent performance. It not only improves construction efficiency and safety, but also reduces labor costs and maintenance costs, providing important guarantees for the efficient, safe and precise conduct of modern construction.

We Hengguan Bearing, have experience in manufacturing opposite bearings and can produce standard or customizable bearings. We have cooperated with many new and old customers at home and abroad. We have a professional technical team and complete equipment and certificates. Trust us and feel free to consult us.

The cross roller bearing is a special type of bearing with a divided inner ring and a rotating outer ring. Because the divided inner ring or outer ring is fixed together with the cross roller shaft ring after the roller and the spacer are installed to prevent separation from each other, the installation of the cross roller shaft ring is simple. Since the rollers are arranged crosswise, only one set of cross roller rings can bear loads in all directions, and the rigidity is increased by 3-4 times compared with traditional models. At the same time, because the inner ring or outer ring of the cross roller bearing is a two-part structure, the bearing clearance can be adjusted, and even if preloaded, high-precision rotation can be obtained.

Unlike ordinary bearings, slewing bearings generally have mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main engine design structure is compact, easy to guide and easy to maintain. Slewing bearings are widely used in engineering machinery, aerial machinery, handling equipment, automation machinery, special vehicles, new energy equipment, ship equipment, lifting equipment, hoisting equipment and other fields.

Since the slewing bearing of the excavator generally works under high load conditions, and the working environment of the excavator is relatively harsh, the slewing bearing is prone to failure, and the most common is various abnormal noises. So what causes the abnormal noise? What should be done to troubleshoot?
