The design of the inner ring rib and the cage and the optimization of materials realize high-speed rotation. NSK's proprietary SHX steel achieves excellent seizure resistance and even higher speeds across a wide range of applications.
Improved lubrication at high speeds by optimizing design of the hard-to-lubricate inner ring rib. A PEEK resin cage suppresses heat generation realizing higher speeds.
Available in both standard and high-speed specifications to meet your needs. Ideal for use on the free rear side of machining center spindles.
The high-speed RX type with ultra high-speeds and heat-resistant long-life SHX steel achieves 4 times longer rolling fatigue life and 20% higher speeds than SUJ2 steel.
