Development of oiless rolling bearings with functional plating

Abstract

Currently, environmentally friendly mechanical products are required, and energy saving is recommended．In order to save energy in mechanical products, it is necessary to reduce the torque of bearings used in mechanical parts．In this experiment, bearing life tests were conducted without lubricating oil, which is a bearing torque factor, inside bearing 51105, but with Ni-P-PTFE plating and Ni-P-B plating on the bearing raceways．As a result, the average life of the bearings without plating was about 100 hours, and the average life of the bearings with Ni-P-PTFE plating and Ni-P-B plating was 150 hours each．
