Strategic Partnership between JTEKT Corporation and the Nadella Group

JTEKT Corporation and the company Nadella Group are starting a strategic partnership allowing the Nadella Group to have the exclusive rights of selling the Nadella Needle Roller bearing Products range to the Industrial Distribution segment, on a worldwide basis. From now on JTEKT Corporation will be a strategic subcontractor and will dedicate its capabilities and resources only to the manufacturing of this product line on behalf of the Nadella Group.

After having conducted a comprehensive study of the opportunities to make use of the market challenges, both parties have decided to concentrate on their own area of excellence. It means manufacturing by JTEKT Corporation, on the one hand and Sales and Marketing for Nadella Group, on the other hand. Active since decades in this specialized product line, the Nadella Group has developed in recent years an aggressive approach not only in terms of Sales but also in terms of Engineering and Marketing support. As the manufacturing partner JTEKT Corporation will not compromise on quality and will continue to invest and re-organize its operations to offer the Nadella Group customers the utmost quality at the most competitive price.

FAQ

What is an angular contact ball bearing?

An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such as silicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear in a similar way to bearing steel—rather than cracking or shattering like glass or porcelain.

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.
