Combining premium-grade materials, optimized design and precision manufacturing, ULTAGE is the new generation of bearings from NTN that delivers unmatched service life, the highest limiting speeds, and the best load capacities on the market to maximize the productivity of your equipment.
Manufactured in state-of-the-art facilities that maintain consistently tighter tolerances through production, ULTAGE spherical roller bearings combine product research, premium-grade materials, and an optimized internal and external design to greatly extend bearing life. These bearings incorporate an optimized surface finish and a high-performance, window-type pressed steel cage for higher rigidity, stability, and better lubrication flow throughout the bearing. All these design features allow for 20% higher limiting speeds when compared to conventional designs, reducing operating temperatures that extend lubrication intervals and keep production lines running longer. The result is greater profitability for our customers thanks to improved uptime and productivity.
Additionally, ULTAGE spherical roller bearings are made from premium-grade steel and contain larger rollers, providing a 65% increase in capacity compared to a conventional bearing and thus resulting in up to five times longer service life. In addition, ULTAGE spherical roller bearings provide up to 35% greater basic static load rating compared to conventional bearings.
Furthermore, our special heat treatment process allows for dimensional stability of the bearing up to 200°C (392°F), all while maintaining high hardness. The combination of high temperature stability and high hardness allows the bearing to achieve a longer life, thus reducing down time and increasing production.
