Leaders in the electric motor market have been working hard to cope with the increasing demand from users for more energy efficient machines. They introduced inverter drives, worked with their suppliers on the quality of the raw materials and copper wires, and also changed their manufacturing processes. When dealing with energy efficiency, every bit helps. For this reason, SKF decided to produce a range of energy efficient deep groove ball bearings to support the demand of many prominent customers. With 30 to 50% lower friction, compared with standard bearings, the energy savings are substantial and the bearing life is extended significantly - in most cases more than double.
These SKF Energy Efficient deep groove ball bearings are available as shielded bearings that feature an optimized design balance between internal geometry, grease, and cage. They dimensionally comply with ISO 15:1998 in a range of selected sizes. Initially, E2 design bearings are available to cover shaft diameters up to 60 mm. This range is appropriate for electric motors up to 37 kW (50 HP).
