What's the failure analysis and renovation of slewing ring bearings?

Slewing bearings are special types of bearings usually used in heavy machinery.The difference between these types of bearings and ordinary bearings is that  they have high pitch value diameters, the way they are mounted on a structure, generally "static" working properties, high load capacity and a large number  of rolling elements.

The slewing bearing is usually selected according to the static load which is calculated by the axial and radial force and the tilting moment.Some  parameters, such as speed, load and working temperature, are needed to properly select the rotating bearing.There are some assumptions to consider:
1) The bearing is made of high-quality materials without manufacturing defects.
2) Select bearing according to load calculation.
3) The bearing mounting is suitable.
4) The grease quality is good and it can reach every corner of the bearing.
5) The bearing is sealed with high-quality seals.
6) The bearing working temperatureis within the range.
7) Ensure proper maintenance.

What are the selection tips for slewing ring bearings?

In the mechanical industry, slewing bearing has been widely used, because the development of slewing ring, varieties are increasing, and how to choose the slewing bearing using in machinery, we must have some understanding.Let me follow FRB Bearings staff to learn about some of the slewing bearing selection techniques.

Bearing type selection
Bearing type is generally chosen by the user's technical personnel according to the use conditions of the supporting products and the bearing load.The sales mainly know whether the actual load of the user is consistent with the selected bearing. If the bearing fails to meet the use demands, the customer should be advised to change the model as soon as possible.
