In order to solve the problems on lightweight, efficient support and lubricating for the attitude control wheel in a micro-small satellite, a method using grease lubricated ceramic bearing to support and lubricate the attitude control wheel was proposed. The static frication torque, power loss, anti-temperature, anti-vibration and life of the wheel using ceramic bearing support and grease lubricating were analyzed through experiments. The results show that the static frication torque and power loss of the ceramic bearing under grease lubricating are less than those of all-steel bearings,and the starting characteristics of the proposed wheel are very well at the temperature from -30 ℃ to 50 ℃. Moreover, the vibration resistance performances of the wheel under the testing conditions equal to the conditions when a satellite is launched perfectly. After the vibration testing, the wheel has been tested for four years under a vacuum degree of 0.02 Pa and a rotation speed of 5 000 min/s and results show the variations of current are less than 1%,which proves that the life of the attitude control wheel has more than four years and can meet the lightweight and life requirements of micro-small satellites in space.
