The technical trend of solid lubricant rolling bearing and linear motion guide was reviewed. Especially, a newly developed oil-free solid lubricant linear motion guide by authors was also reported in details in this present. The rolling ball of the guide was coated by sputtering molybdenum disulfide (MoS2) and some special transition metal simultaneously, while the spacer ball made of polytetrafluoroethylene (PTFE) was also applied to the guide. By this way, a composite solid lubricant with excellent wear resistance properties was provided and there has been no any organic solvent and binder added, resulting in lower particle generation and low lever of out gas. It is expected that the oil-free solid lubricant linear motion guide could be applied to high temperature, high vacuum, radiation and space utilizations.
