Koyo is one of the 6 largest global roller bearing manufacturers. One of its core competences is the design and manufacturing of TRB's. To meet the global energy saving demands (to reduce fuel consumption, CO2 emission, etc.) Koyo has been developing light friction type TRB's progressively over the years. For more (technical) details read the related article in BearingNews:
The price increase for Koyo bearings will be effective as of the 1st of February 2019:
4,9% (flat increase) for all main series
Should you have any question please contact your usual Koyo business representative.
Van 18-20 september vindt de Industriele TIV beurs in Hardenberg plaats, waarbij JTEKT/Koyo aanwezig zal zijn met een eigen stand. JTEKT is een Japanse firma aktief in met name de algemene (automobiel)toeleveringsindustrie. Koyo, de lagerdivisie van het Japanse JTEKT, behoort tot de 6 grootste wereldwijde spelers in de lagermarkt. Naast producten voor de automobielindustrie wordt een breed pallet aan lagers voor allerlei industriele toepassingen aangeboden. xxx
Mocht u naar de TIV beurs gaan, twijfelt u dan niet om onze stand 316 te bezoeken, voor algemene vragen of zakelijke besprekingen.
MOTEK, the annual international trade fair for automation in production and assembly, took place on October 8-11 in the Exhibition Centre in Stuttgart. It is one of the largest fairs in the southern - German speaking - area, exhibiting in 6 halls with more than 800 participating companies. Kuenemund Waelzlager GmbH & Co. KG - an inherent participant to this trade fair - also participated this year by showing a large variety of their know-how and in-house products. Complementary; Kuenemund showed some material that was provided by Koyo, mainly housing units and ball&roller products. This joint activity underlined the close cooperation and partnership between both parties with Kuenemund acting as Koyo's distributor in Southern Germany. Common future activities are already in the planning - also for the next episode of the MOTEK fair - so stay tuned for future events that will be represented together.
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.
