With the NSKHPS™ series, NSK has developed spherical roller bearings that offer twice the lifespan and a limiting speed that is up to 20% higher compared to conventional spherical roller bearings.
Thanks to their improved wear resistance under high speeds and high mechanical loads, the NSKHPS™ bearings can cope with all types of demanding applications. Includ-ing, for example, pumps and compressors, cranes and other hoisting devices, paper machines, mining technol-ogy and the steel industry.
Since demand for NSKHPS™ bearings is continually on the increase, NSK has optimised the series and signifi-cantly upgraded and extended the product offerings. Bearings with bore diameters of up to 260 mm are now available.
The NSKHPS™ CAM bearings are equipped with a guide ring – giving extremely precise roller guiding and the solid brass retainers offer very high wear resistance. (The EA series achieves these qualities through a special surface treatment of the steel plate retainers). Optimal design of the inner and outer ring is a prerequisite before the additional, larger rollers may be installed.
These design features not only increase the life span and the wear resistance, they also increase the dynamic load rating by up to 25%. As a result, the new "large size" NSKHPS™ spherical roller bearings can allow “down-sizing” in high loaded drive assemblies for demanding applications.
