Q: What is the proper break-in procedure on NSK electro spindles? If the spindles have …

The following procedure must be followed to ensure proper motor spindle operation and longevity. The grease inside the bearings will settle during transportation, storage or service. If the motor spindle suddenly runs at high speeds, grease will evacuate from the bearings, causing excessive heat resulting in bearing damage.
