Each type of slewing bearing corresponds to a load-bearing capacity curve, which can help users make preliminary selections of slewing bearings. There are two types of curves in the graph. One is the static load curve, which represents the maximum load that the slewing ring can bear when it remains stationary. The other is the limit load curve of slewing bearing bolts, which is determined when the clamping length of the bolt is 5 times the nominal diameter of the bolt, and the pre-tightening force is 70% of the yield limit of the bolt material.
slewing bearing selection
Selection of structure type: There are four types of commonly used slewing bearings: single-row ball type, cross-roller type, double-row ball type, and three-row column type.
According to our experience and calculations, we have the following conclusions:

When Do < 1800, single volleyball is the preferred type;
When Do>1800, three-row column slewing ring is preferred.
If the slewing ring with the same external dimensions, the load capacity of the single-row ball type is higher than that of the cross roller type and the double-row reducing type, the Q series single-row ball type slewing ring has a more compact size, a lighter weight, and a better cost performance. The preferred series of single volleyball style. slewing bearing selection
