On February 5-6 Koyo participated with a representative booth at Ditzinger’s DITEC fair in Braunschweig. This was an excellent opportunity to meet with industry representatives, students and experts and the Ditzinger team focussing on MRO (Maintenance, Repair & Overhaul) requirements for all types of manufacturing industries in Northern Germany and other regions. The cut-open Audi DL382-7Q transmission, which includes several Koyo bearings and a JTEKT/Torsen LSD (Limited Slip Differential) attracted a lot of attention.
The price increase for Koyo bearings will be effective as of the 1st of April 2020:
2,9% (flat increase) for all main series
Should you have any question please contact your usual Koyo business representative.
The next Koyo European Distributor Convention, which normally takes place every two years and which was held for the last time in Sevilla in 2018, will be moved ahead one year to take advantage of the memorable fact that Koyo was founded in 1921, which makes 2021 the 100 year anniversary of Koyo
This glorious year for Koyo, which will be appropriately celebrated globally, will provide an excellent opportunity to organize a special European Distributor Convention, focusing on the long Koyo history and the achievements reached so far. Details of the 100 years Anniversary 2021 Convention, which will most probably be held in the month of May, will be informed in due time.
On February 5-6, 2020, JTEKT will be proud to participate to the Ditzinger’s DITEC fair for the 5th time. JTEKT, representing it’s Koyo bearing brand, will be one of around 60 participants to the DITEC fair, that focusses on MRO (Maintenance, Repair & Overhaul) requirements for all types of manufacturing industries in Northern Germany and other regions.
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.
