Large diameter slewing bearings are critical components in many applications.Common commercial applications of the slewing bearing include aerial lifts, hydraulic excavators, boom cranes, and tunnel boring machinery. Military applications of the slewing bearing include tank turrets, missile launchers, communication antennae, precision radar antennas, and gun mounts. This article mainly introduce how to prevent the failure of your slewing bearing.

How to choose the right slewing drive?A slewing drive is a gearbox designed to handle radial or axial loads using high rotational torque. In addition, the slewing ring bearing, at the heart of the drive, enables it to withstand high overhung or moment loads. A descendant of the “worm” screw, slewing

Slewing bearings are bearings of large dimensions (> 400 mm) used in different applications, such as cranes, turning tables, excavators, wind turbines etc.. Their main function is to connect structural parts, allow relative rotation between them and transmission of loads. This article mainly introduces how to calculate the capacity for slewing bearing.

In the practical application of slewing drive, many times due to the improper method of user in the process of installation, use and maintenance, the slewing drive can not be used properly, which makes the performance of the main engine decline. Therefore, we should pay enough attention to the installation, use and maintenance of rotary drive. Today, we analyze some detail factors that can not be ignored in the correct installation of slewing drive, so that the slewing drive in the installation process to play the maximum performance.

Slewing ring bearing is now used more of a kind of accessories, in the process of daily use, how much will be heat, but this kind of situation if not timely solve, is larger for bearing damage, to introduce today is about what causes slewing ring bearing of heat, and how should be handled correctly.

The four-point bearing is a separable structure, and a single bearing can replace the angular contact ball bearing with front combination or back combination.
