Can graphite copper sleeves be lubricated with grease such as butter?

First of all, it is clear that the graphite copper sleeve can be lubricated with butter and other grease.
Some misconceptions are that filling the graphite copper sleeve with grease will destroy the solid lubricating film built by the graphite copper sleeve during operation, leading to lubrication failure or attenuation. But in fact, the performance of the graphite copper sleeve will be greatly improved under the combined action of the lubricating oil film formed by adding lubricating grease and the solid lubricating film composed of graphite.
The Mingxu bench test has proven that the friction coefficient of the graphite copper sleeve in the dry friction state is 0.15, and the friction coefficient is significantly reduced to 0.03 in the lubricated state; the maximum PV value (N/square millimeter*m/s) in the dry friction state is 1.65. It is 3.25 in the lubricated state; the maximum linear speed is 0.5m/s in the dry friction state and 1m/s in the lubricated state.

The above measured data proves that lubricating the graphite copper sleeve will not only not damage its original performance, but will double its performance. Lower friction coefficient, higher load-bearing capacity, faster sliding speed and longer service life.
Regarding the problem that lubricating grease will destroy the solid lubricating film, it is true that the original solid lubricating film will not be able to maintain its integrity after lubrication, but the new composite lubricating film constructed by the lubricating grease and the solid lubricant is better than the original single solid lubricating film. The lubricating film performance is better; moreover, after the lubricating grease is exhausted, the graphite copper sleeve can quickly build a new solid lubricating film.Mingxu produces graphite bronze bushings and other related self-lubricating bushings and bearings.
