Slewing drives typically employ either a spur gear or a worm gear to achieve rotation. Spur Gear drives are used for high rotational speeds and quick acceleration at nominal-to-low torque loads. Worm gear drives, on the other hand, are slower in speed but can magnify an input torque at much higher ratios than a typical spur gear system. This article will introduce how to install slewing drive. Read More

Slewing ring bearing can be used in a variety of mounting fixed forms.In order to meet some special application environment, the installation method may change.Some important details of the actual design of slewing ring bearing, such as the thickness of the mounting plate, the location and number of reinforcing members, and the bolt length, should be determined by the equipment designer. This article mainly introduces how to gearing up your slewing ring bearing. Read More

The slewing drive is an important part used in many construction machinery nowadays, because of its utilization rate and importance, so it will be damaged in use. As a key part of the main engine, whether the rotary drive device can work properly is related to the performance of the main engine. The cold winter weather will have a certain impact on the normal operation of the slewing drive. For users, it is important to prevent damage of slewing drive, so how to extend the life of slewing drive? Read More

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 Read More

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.
