Mining Week Exhibition in Kazakhstan 23-25 June 2015

The mining and metallurgical sector is one of the most competitive and dynamically developing industries in Kazakhstan. In the nearest future, the sector shall aim at the creation of new manufacturing in the metallurgical industry, production of high value-added products ensuring both, growth of output of high-technology products and expansion of its export to foreign markets and meeting of domestic needs.

The Mining Week Kazakhstan is the largest international exhibition for mining and metallurgical industries, which will showcase the latest equipment, services and technology. This specialized exhibitions attracts local experts but also representatives from countries worldwide looking for partnerships and investments.

In order to support the new partnership with our distributor Nova in Kazakhstan which mainly services the heavy industry in central Asia, Koyo Deutschland GmbH made a joint participation at the Mining Week exhibition.

Mr. Yermek Duiseyev – Director of Nova expressed his wish to supply the Kazakh Market with high quality bearings to secure a long service life for the equipment in the heavy industry. This exhibition is renowned in central Asia and visited by specialists from the heavy industry. Global players like ARCELORMITTAL, FERRIT, etc. visited the booth. Read more

This was a great opportunity to highlight our Koyo products, services and capabilities. Nova and Koyo Deutschland representatives also had the great opportunity to visit ARCELORMITTAL TEMIRTAU.

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.
