This work is improving the performance properties of greases additives graphene concentrate. It has been established that the addition of 1% graphene concentrate to the lubricant Solidol J contributes to an increase in its anti-wear properties by more than 30 percent. With the enrichment of commercial grease Lithol-24 with graphene concentrate, a decrease in the diameter of the spot of wear of the balls was determined at the plate size from 0.36 mm to 0.30 mm. As a result of testing lubricants in rolling bearings, a decrease in the heating temperature of bearings operating on lubricants enriched with graphene concentrate was found in comparison with commercial lubricants.
