The apparatus consists of a plain steel shaft excavated in a bearing and directly driven by a FHP Motor. The bearing is freely supported on the shaft and sealed at the motor end. The speed of the motor is controlled by the speed control unit. One compound pressure gauge is mounted on Bearing to measure the pressure at different position around the circumference. Bearing are free to rotate and can be adjusted at any position of circular scale. The bearing are loaded by attaching weights to the arm supported beneath it.
