FAQ

Safety

Slewing bearings generally carry larger loads in their weight ration design, these designs have larger safety factors embedded to ensure that utilization can be applied across a broad spectrum, resulting in satisfying the load capacity and longevity within the service life

 

Load Curve

The rotational speed of a slewing bearing is generally slow, therefore, its load capacity mainly refers to the static load capacity. There are several methods of theoretical calculation of the static load, in which the load curve (load-moment) is one of the most common methods used.

 

Most slewing bearings work under eccentric loading, they also carry tilting moment loading as well as axial and radial loading. Calculations for loading capacity were previously carried out by manual methods, resulting in being very time consuming and very inefficient. LTZCtoday are using computerized mathematic modeling to provide the load curve calculations across a whole array of extreme applications. The load curve is the allowable load limit for slewing bearing during its working condition, this calculation is the main factor that is used in the selection of any slewing ring.
