The current use of bearing can usually divided into rolling bearing and sliding bearing; The operation principle of the rolling bearing and sliding bearing can pass title can be the difference, conflict is when the rolling bearing homework attack roll, and the sliding bearing of homework attack is sliding conflict; The conflict of the rolling force intrusive first depends on production precision; Conflict and sliding bearing force of intrusive first depends on the slip plane of the bearing material. Sliding bearing surface usually have self-lubricating function.
Metal sliding bearing is currently the most used three layer composite bearings, the bearings are generally based on carbon steel substrate, through sintering technology in steel plate on a layer of spherical copper powder sintered first, and then in the copper powder ?
