Name：Which one is wear-resistant, steel sleeve or copper sleeve
Content：
In terms of wear resistance, steel sleeves are more wear-resistant, and in actual use, steel sleeves are less commonly used because using steel sleeves will wear the shaft quickly. Usually, when designing bearing pad type sliding bearings, the shaft and sleeve must be made of two materials.
Due to the fact that the shaft is rotating and the bearing shells are fixed, friction will inevitably occur during rotation, resulting in wear on the shaft and bearing shells. The machining and disassembly accuracy and assembly difficulty of the shaft are relatively high, and the fixed maintenance or replacement of the bearing bush is relatively easy. Therefore, when selecting materials, it is necessary to consciously choose softer bearing bush materials, such as phosphorus tin bronze, aluminum iron bronze, tin zinc lead bronze, etc. According to different usage conditions, different copper alloys are selected, and the material selection of the shaft will be harder or more wear-resistant.
In almost all shaft bearing bush fits, steel materials will be used for the shaft and copper materials will be used for the bearing bush. To be precise, copper alloy is a tin based and lead based bearing alloy with anti friction properties. This is because copper materials are not as wear-resistant as steel materials. In order to protect the shaft, copper materials are chosen as bearing shells.
Our company produces various copper sleeves through centrifugal casting, continuous casting, and extrusion methods, including copper bushings, copper sliding plates, copper turbines, copper washers, flange sleeves, self-lubricating bearings, etc. Copper sleeve materials include: phosphor copper, brass, tin bronze, aluminum bronze, etc.
