Bearing /172A59-73320/ of travel final drive usually is angular contact. They task is to minimize the friction resistance during work of the planetary gearbox.
Bearings installed in excavators of 1.5-50 tone weight are usually divided into two types. These are tapered roller bearings and angular contact bearings.
The angular contactor bearing /172A59-73320/ is constructed in such a way that the inner and outer tracks of the bearing are asymmetrically positioned. This is to reduce the working area of the reducers and increase the pressure resistance. There are two types of angular-contact bearings in excavators: single-row and double-row.
Angular-contact ball bearing
The angular-contact ball bearing has an open structure to maximize oil flow while minimizing friction.
Bearings of this type are very sensitive to the lack or poor quality of the oil. In addition, due to the asymmetrical design of the bearing, it is virtually impossible to remove it from the radiators without damaging the bearing /172A59-73320/. Mostly the bearing balls spill out.
There are only a few bearing manufacturers of the reducer on the global market. Hence there is such a big problem in their purchase and a fairly prohibitive purchase price.
We will pay between 30 € and 1000 € for the asymmetric bearing of the medium-class hub, depending on the type of bearing and its size. Hence, such big problems in the valuation of repair of this type of components.
