The axis and drum can use graphite powder lubrication
This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
Of course, you can not use graphite lubrication, it will damage your parts. You can still use grease or butter, and the middle axle is better with butter
No, graphite powder is suitable for high temperature environment, and the lubricating effect is better than that of lubricating oil
