Travel bearing: the main bearing of the excavator travel gearbox

1. Excavator travel bearings mainly include angular contact bearings and thin-walled tapered roller bearings. These two types of bearings have the advantages of being able to withstand high-strength radial and axial loads at the same time. They have a stable structure, low noise and low running wear rate.

2.About the installation of excavator travel bearings:

The environment where the bearing to install bearing should be selected as much as possible: dry, dust-free area, and should be away from equipment that will produce metal debris and dust. When installing in a complex environment, pollution should be minimized.

The gear oil in the travel gearbox of the excavator should be checked regularly. It is forbidden to work without lubrication of the excavator  travel bearing, keep the excavator travel gearbox well sealed, and not expose the excavator travel bearing to a large amount of dust. Working under extreme conditions pay more attention to checking whether dust, dirt, gravel... whether it enters the excavator gearbox and may damage the excavator travel bearings.

1). Wear and tear during normal use.

3). Improper operation in the process of installing the excavator travel bearing leads to a reduction in service life.
