Advantages of insulating bearing coating:
Good insulation performance. Special sealing method is adopted. J20aa coating can effectively insulate even in humid environment. Insulated bearing can be interchanged with standard bearing. For special occasions, such as outer ring rotation, it is recommended to use bearing with j20c coating on inner ring.
The driving end adopts the cylindrical roller bearing nu215-e-tvp2-f1-j20aa-c4 as the non positioning bearing;
The non drive end adopts the deep groove ball bearing 6215-m-j20aa-c3 as the positioning bearing.
