Release of Spherical Roller Bearing for use in Vibration Machinery by NSK
NSK has developed long lasting spherical roller bearings to be used in vibration machinery at mining facilities. The durability of newly released roller bearing has been made possible through special groove that has been created on the raceway of the outer ring for controlling the slippage action of the rollers. In addition to this, the curvature factor between the raceway and spherical roller has been optimized, resulting in reduced slippage and the accompanying initiation stress between the roller and the contact surfaces of the outer and inner ring raceways.
Furthermore, NSK has successfully stabilized the load distribution by controlling radial internal clearance and bearing dimensional tolerance factors. NSKL is targeting the annual sales of one billion JPY by 2011.
