The importance of the slewing bearing(www.slew-bearing.com) of the excavator is self-evident. Various loads and moments on the working device need to be transmitted to the underframe through the slewing bearing. Because the slewing ring carries the overload work, it is also the part of the excavator

Slewing ring bearing installed in a wide variety of applications,but for some of machine the bearing clearance and precision is required.However,Xuzhou Wanda slewing bearing clearance and precision is best for the machine and work very well. l Slewing bearing precision stardand 1. The precision of the slew

The slewing ring environment and using temperature:The slewing ring working temperature is normally from -300C to +700C. If the user needs to adapt to the lower or higher temperature slewing bearing, our company can carry out special design. Slewing bearings can be used in particularly harsh slewing

Inner Ring and Outer Ring The bearings are comprised of two rings, each of which contains a precision raceway that is induction hardened on the surface to a specified depth. Each ring is made from a medium carbon steel forging.slewing bearings(http://www.slew-bearing.com/SLEWING-BEARING-pl502823.htm

Service Factors To determine if a Slewing Ring bearing is appropriate for an application, a SERVICE FACTOR is applied. Refer to the table below for a guide to the service factor to apply to your application. The load rating curves shown in this catalog are approximate, and represent an application s

Slewing bearings are generally selected on the basis of the static load, which is calculated using the forces for axial and radial loads coming on it as well as the tilting moment. For correct selection of the slewing bearing, certain parameters such as speed, load, and operating temperature are req
