SKF, a global supplier of bearings, seals and lubrication systems, has developed spherical and cylindrical roller bearings. Extensive testing results verify significant friction reduction compared to SKF standard bearings.
SKF energy-efficient spherical roller bearings exhibit at least 30% less friction and corresponding reduced energy consumption, considerably lower bearing temperature, extended grease life and extended relubrication intervals.
Five sizes of open bearings are the first to be introduced for industrial ventilation fan applications as part of the total SKF energy-efficient solution for fans. Additional sizes will be offered based on customer demand.
The first SKF energy-efficient cylindrical roller bearings to be introduced are the NJ series, which are designed to handle axial-loads in one direction. Compared to the current SKF standard NJ series bearing, the new SKF energy-efficient cylindrical roller bearings exhibit a friction reduction of at least 30% in axial loaded applications and have a higher dynamic load rating. These new, ultra-low friction bearings are intended for a wide range of applications. Initially, they will be introduced for industrial and wind energy transmissions.
