NTN 'ULTAGE' Spherical Roller Bearings - CBC Bearings

Up tofive timeslongerservice lifeLonger service life and higher rotawhile contributing to moLongerService Lifethe industry’s highest load capacity.HigherRotational Speedallowable rotational speedemploys a pressed steel cage.The back face of the cage providesa guide function that eliminatesthe guide ring.ImprovedEase-of-Useaccepts lubricant.“ULTAGE” (a name created from the combination of “ultimate,” signifying refinement, and “stage,” signifying NTN’s intention that this series of productsbe employed in diverse applications) is the general name for NTN’s new generation of bearings that are noted for their industry-leading performance.

The ULTAGE® AdvantageThe industry’s highest load capacity Theindustry’s highest allowable speed Pressed steel cage providedas standard. Compact, lightweight design Results in approximately a 30% reductionin volume ratio and mass ratioImproved ease-of-use
