Spherical Roller Bearings | NSKHPS

Supplier: NSK Australia

NSKHPS Spherical Roller Bearings are state-of-the-art material technology bearings, offering high speed and load ratings that can enable downsizing and are suitable for a wide variety of applications.


Extremely pure Z-steel construction and improved internal design characteristics are deciding factors in the increase of performance. High precision finishing of the inner and outer rings, newly-developed surface treatments of the rollers, super-finished raceway surfaces, improved cage geometry and cage stiffness: these are just some of the advantages of NSK's wear-resistant NSKHPS Spherical Roller Bearings.

NSKHPS Spherical Roller Bearings do not just make a convincing case through their compact construction but, by achieving double the operating life of conventional bearings, they also significantly reduce downtime and the associated costs. NSKHPS series bearings have a temperature stability up to 2000C.
