Micro traction drive is a device to transmit driving force modified from angular ball bearing. The micro traction drive consists of an input/inner ring, an outer ring, a rolling element, a retainer/output shaft, and a casing. In addition, the micro traction drive of the tandem type that combined two bearings was developed to obtain a big reduction ratio. As a result, we are able to attain the reduction ratio 7.3. Traction oil on the market was sealed in the test piece for oil bath lubrication. Input shaft could be driven with a motor in ultra high speed. Power absorbing type test equipment was made the efficiency and temperature of micro traction drive operated at high speed were successfully measured. In the result of measurement, temperature rise are a few and it turns out a micro traction drive can be used by ultra high-speed.
