NSK Bearings cut friction by half

NSK Bearings cut friction loss

NSK has announced that it has developed energy-saving bearings for high-efficiency motors that halve the friction loss of rolling bearings used in conventional products and thus contribute to a reduction of electric power consumption in high-efficiency motors. According to NSK, the friction loss results from an optimisation of bearing design.

Enhancements in the efficiency of bearings enable operators to meet the rising standards for global standards for motor efficiency. As the International Electrotechnical Commission (IEC) efficiency level for motors progresses to IE3 and IE4 over the coming years, the demand for bearings with low friction loss will increase. NSK claims that its bearings conform to the extremely demanding IE3 and IE4 efficiency standards of the IEC, enabling reduced power consumption of bearings in industrial motors.
