How to select crane slewing bearing type ?

Slewing ring bearings is a bearing that can bear a lot of weight, often used in different industries.And there are many types of swing bearing, different types have different use case.But generally speaking, slewing ring are more used in construction machinery, so what type of slewing bearings should be used by cranes?

FRB BEARINGS technology personnel according to their years of related experience, according to crane is a large machinery, so choosing the slewing bearing must have a lot of tolerance, and compact structure.Therefore, the crane slewing bearing can choose three rows of roller type turntable bearing, single-row four-point contact ball type slewing ring, which can increase the overall contact area and withstand various loads at the same time. The diameter of this type slewing ring bearing is also large, which is specially used for heavy machinery equipment.

Common faults and troubleshooting of mobile cranes slewing bearings

Mechanical failure
Crane slewing bearing plays the role of connecting the truck and chassis  parts in the rotary mechanism, and also supports the whole rotating part of  crane.If the steel ball in the swing bearings is damaged and the raceway  abrasion will affect the work of the rotary mechanism, in severe cases, the  rotary mechanism will be heavy and make noises, and the pressure of the  rotary hydraulic system will exceed the rated value.When hoisting and  unloading are carried out at the stop of rotation, the vibration amount of  the slewing bearings will be too large at the moment of falling and falling  together, indicating that the clearance amount of the slewing ring has  seriously exceeded the limit.At this point, the turntable bearings should  be repaired or replaced.

The general causes of mechanical failure are inadequate maintenance and  improper use.
