How often do bulldozer rollers need to be replaced?

The main function of the roller is to support the weight of the excavator and the bulldozer, so that the track moves along the wheel to complete the operation. So how often do bulldozer rollers need to be replaced? Today I will give you a brief introduction.

1. The roller is used to support the weight of the fuselage of construction machinery such as excavators and bulldozers. At the same time, it rolls on the guide rails (rail links) or track shoes of the track. It is also used to limit the track and prevent lateral slippage. When When the construction machinery equipment is turned, the rollers force the track to slip on the ground.

2. As for how often the bulldozer rollers need to be replaced, in fact, if the gap between the bulldozer rollers is too large and they crack, they need to be replaced. But it also depends on the specific use environment. If carefully maintained, the service life is about 20,000 to 30,000 hours.

3. The bulldozer rollers often leak oil due to inaccurate installation. Therefore, certain protective measures should be taken during the installation process. The long-distance running of the machine will cause the rollers and the final drive to generate high temperature due to long-term rotation. , The viscosity of the oil decreases and the lubrication is poor, so it should be shut down frequently to cool down and prolong the life of the lower body.

In general, how long does the bulldozer support roller need to be replaced, it needs to be judged according to the actual situation, it needs to look at our use environment, etc. In order to prolong its service life, we need to do certain inspection and maintenance measures.
