NTN large size tapered roller bearings (ULTAGE metric series, OD>= 270mm) deliver longer life, higher load ratings, and higher speed capabilities. Developed as the new standard of NTN bearings, the ULTAGE series will contribute to improvements in industrial machinery today and into the future.
Greater high load capacity by optimizing internal design
Longer maintenance intervals
Higher Load Capability
Allowable misalignment 0.0017 (6’)
Higher Limiting Speed
Up to 10% increase of allowable speed by optimizing the inner ring, large-end rib, and the roller end
"ULTAGE " (a name created from the combination of "Ultimate," signifying refinement,and "Stage," signifying NTN's intention that this series of products be employed in diverse applications) is the general name for NTN's new generation of bearings that are noted for their industry-leading performance.
