NTN Receives the 2017 “CHO” MONODZUKURI Innovative Parts and Components Award, Automotive Components AwardOctober 26, 2017Press Release

NTN Corporation (hereafter, NTN) has received the Automotive Components Award of the 2017 “CHO” MONODZUKURI Innovative Parts and Components Award sponsored by MONODZUKURI. Nippon. Conference and Nikkan Kogyo Shimbun, Ltd.

Award Name

“CHO” MONODZUKURI Innovative Parts and Components Award

2017 “CHO” MONODZUKURI Innovative Parts and Components Award, Automotive Components Award

Awarded Product

ULTAGE * Tapered Roller Bearing for Automotive Application

  • ULTAGE is the name for NTN's new generation of the world's highest standard of bearing series, and expresses the “ULTIMATE” performance on any type of “STAGE”

Product Overview

The tapered roller bearing for automotive application realizing the world's highest standard of high load capacity and high-speed rotational performance

1) Standard type: 1.3-times higher in high-load capacity and 2.5-times or more in bearing rated-life (compared to conventional products)

Equation of contact surface pressure between the rolling element (rollers) and raceway (inner and outer ring), even when there are high loads or unbalanced loads

2) High-performance type: 3.8-times or more in bearing rated-life (compared to conventional products)

Applying NTN's proprietary special heat treatment (FA treatment)

3) Approximately 10% increase in permitted rotational speed

Limiting increases of temperature by optimizing shape of the sliding contact zone between the rollers, inner ring and retainer

Reason for Receiving the Award

With the optimal design technology for the ideal shape of tapered rollers, which realizes longer bearing life with an equitation of the contact surface pressure and internal stress, this product delivers the world's highest standard of high-load capacity and high-speed rotational performance. These features are realized with NTN's proprietary processing technology to make the optimal shape of rollers which is difficult to achieve so far.

This product allows the use under the harsh conditions derived from downsizing and weight saving of transmissions and differentials. These features enable to reduce fuel consumption, contribute to low-carbon society and finally resulted in it in being received prize.
