Koyo Bearings, a division of JTEKT Corporation, has introduced a new generation of Spherical Roller Bearings – the JTEKT Hyper Strong (JHS) Series.

The Koyo JHS Series Spherical Roller Bearings features a longer service life, higher maximum speed, improved axial load performance and higher maximum temperature allowance.

Will you also be there at the Agritechnica upcoming 8-14 November 2015?

Agritechnica is worldwide known as the innovations forum for the entire agricultural sector where leading technologies and new developments will be presented. The exhibition is an ideal platform for internationally operating enterprises to present innovative products and concepts for the future crop production. It also provides excellent opportunities to share and exchange information and knowledge related to agricultural equipment and machinery.

EPTDA, The European Power Transmission Distributors Association is the largest pan-European organization of distributors and manufacturers of power transmission and motion control products. These power transmission and motion control products are found in countless of industrial, as well as every-day applications and devices. EPTDA also provides their members custom-designed business tools, targeted intelligence analyses and other global reports on a regular basis.

The International Frankfurt Motor Show (IAA) is the world's most comprehensive show of the automotive industry for everybody who develops, manufactures or uses passenger cars. A special feature is the large presence of suppliers throughout the whole automotive value added chain. Around 400 exhibitors from the supply industry are presenting their products.

On the 19th and 20th of June 2015 Koyo Deutschland GmbH participated successfully in the Phaeton Expo, Kazakhstan.

In preparations for this great event, Phaeton scheduled a forum for all their business partners and suppliers the day before the start of the official in-house trade fair.

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.
