The importance of excavator slewing support in machinery is indescribable, which plays a variety of loads and torches. And slewing bearing in excavator is not missing, but also honor all kinds of faults, use a period of time to replace the new bearing. Therefore, today, Xiaobian will say that five points should be noted in the replacement and disassembly of excavator slewing support.

Five major matters of replacement and disassembly of excavator slewing bearing:

1. Choose the right venue

The reason why we should choose the right site is that the ground should be flat when the slewing bearing is replaced. There is a large space, the upper and lower parts shall be separated and lifted during replacement, so a large site space is required.

2, lifting should be careful

When replacing the bearing, it is necessary to transfer the upper structure of the excavator to another place. At this time, the crane should be used. Whether it is dismantled or installed, the hoisting wire rope must be hung up to ensure the safe lifting operation.

3. Safety

In the process of disassembly, a crane will not be used, but a jack or stone will be used to cushion the upper part for replacement. And this replacement risk index is very high, remember to be safe in the replacement.

4, choose the right slewing bearing brand

There are many slewing bearing manufacturers on the market, brands are blooming everywhere, and the quality of products is uneven. If you choose to replace bearings, you can not be cheap in the selection, but choose durable and reliable bearings.

5, screw tightening, can not lack of lubrication

The slewing bearings are replaced with new ones, so the screws should also be replaced to prevent hidden injuries. At the same time, the replaced screws must be tightened, and lubricating oil should be applied to reduce internal friction and improve the service life of bearings.

Replacing the slewing bearing of the excavator is not a small matter. It is necessary to be careful to do the above five points well to avoid various problems of disassembly and assembly.
