An apparatus and method for testing a spindle are provided. The apparatus includes a rotational load device and a linear load device. The rotational load device is connected to the spindle via a shaft and configured to rotationally load the spindle. The linear load device is configured to apply a predetermined linear load on the shaft, so that the linear load is at least partially transmitted to the spindle. The spindle can be subjected to various linear and rotational loads to determine the effectiveness of the spindle, and the performance of the spindle can be measured.
