The graphite copper sleeve is considered from the perspective of friction loss. As a bearing material, the smaller the friction coefficient, the better. Graphite has the excellent wear coefficient of the excellent steel sleeve lubricating bearing. So, what should be paid attention to when installing graphite copper sleeve?
In terms of structure, graphite is a solid material, which can be lubricated without oil, reducing the lubrication system of graphite inlaid bearings and reducing the failure rate. Graphite has high chemical stability.
Distinguish the tight ring and loose ring of the bearing. According to the inner diameter of the bearing, the difference between the diameter of the hole is 0.1-0.3mm.
distinguish the static parts of the mechanism, that is, the parts that do not move, mainly refer to the assembly. No matter what the situation, the loose ring of the bearing should always rest on the end face of the stationary part.
Graphite copper sleeves are cheap and versatile; if metal is used as a bearing, according to what you said, graphite bronze bearings must be operated at high temperatures. Obviously ordinary materials are not acceptable. Materials with high temperature strength need to be customized. The price is not several times. Dozens of times or hundreds of times may not be able to be done. First of all, the materials are hard to find.
