On request, in motors the single-row roller bearings can be built-in series NU.
Remarks: table is valid for all polarities of single and multi-speed motors and for all mounting
arrangements acc. to IEC 60034-7 (EN60034-7)
•
nominal bearing life under rated working conditions is minimally 40000 working hours for 4, 6 and
8-poles motors, and a minimum of 25000 working hours for 2-poles motors connected to 50Hz
power supply network.
Bearing regreasing interval determining diagram:
Example :
Deep-groove ball bearing with inner dia. of 40mm and rotational speed of 1500 rpm needs to be
regreased approximately after every 6000 working hours (interpolation).
