Upgraded performance for precision
bearings
NTN is set to upgrade the specifications of its precision grade angular contact ball bearings for use in machine tool spindles and other precision equipment.
To expand its sales of precision grade angular contact ball bearings used in machine tool spindles and other precision equipment, NTN is making a full product changeover by upgrading the specifications for these bearing series In July of this year, the 70U and 79U bearing lines will be introduced as part of NTN's Ultage Series of precision machine tool spindle bearings

NTN has developed an optimised spherical roller bearing with integral seals.
Heat treated steel boosts bearing performance
FA tapered roller bearings are produced using steels subjected to a novel form of heat treatment that produces ultrafine austenite grains less than half the size found in conventional bearing steels.
The Ultage line of bearings have already racked up impressive results among machine tool manufacturers far and wide.
The 70U and 79U series rank number-one in the world in terms of high speed, high load capacity and high strength among standard bearing steel, precision grade angular contact ball bearings.
The 70U and 79U series are NTN's next generation precision bearings and will be commercially available all over the world as a "new global standard" with expected sales of Y3 billion annually.
These 70U and 79U bearings have optimised component designs (inner ring, outer ring, retainer and rollers) developed after meticulous research for applications using air-oil or grease lubrication.
Air and oil flow have been optimised for air-oil lubrication applications, and grease retention and agitation features have been designed specifically for applications requiring grease lubrication.
Special features include a new high strength resin retainer using an innovative pocket section structure, resulting in the highest speed ratings currently available, improved angular load capacity, and longer service life.
