The surface of the electric machine can be hot. Use correct protective equipment (heat
resistant gloves) when you handle the electric machine.
The information of bearing lifetime and bearing grease lifetime are estimations only to
provide a magnitude of them. The bearing lifetime and bearing grease lifetime in customer
application may vary. Danfoss is not responsible for the actual bearing lifetime in use. For
further information, contact Danfoss representative.
The maximum relubrication interval in operation is six months. The amount of grease per
relubrication is 20 g.
The relubrication interval depends on the used rotation speed and bearing temperature, and is
presented in the Figure below. The different curves represent different bearing temperatures. The higher
the temperature is and the higher the rotation speed is, the lower the relubrication interval is.
