Automechanika is the world’s leading trade fair for the automotive industry. This exhibition is a very important event for the Automotive OEM and Aftermarket industry. It took place on 6-9 April 2017 in Istanbul, Turkey. The Automechanika Istanbul closed with a record number of 1.217 exhibitors and 43.874 visitors from around the world. All professionals from the Automotive Manufacturing, Distribution and Repair sectors in the region were present at Eurasia’s number one event full of innovation and knowledge sharing.

Rulman Ticaret-Koyo’s distributor in Turkey has participated in this important event and offered Koyo the opportunity to join forces and to promote our Koyo bearings brand at their booth. Visitors from all over the world visited the booth and a lot of very interesting meetings with Rulman Ticaret’s and their potential- and existing customers took place during this event. The fair was a good opportunity to promote and show Koyo’s product capabilities and technology. Rulman Ticaret is led by the family Bayindir and their focus lies mainly on the automotive spare parts business which reflects 70% of their turnover. The rest is made by the forklift and crane spare part business. Since 2010 the business relationship between Koyo and Rulman Ticaret has been intensified and the successful efforts were reflected by a turnover increase of more than 5 times. Rulma Ticaret is using mainly Koyo products as a premium brand to serve the Turkish market. The target is to increase the "Turkish market focused inventory" in order to cover every demand in a very short lead time.

During September 12th - 15th Koyo UK attended and exhibited at Cromwell's 'The Event' held at Donington Park exhibition centre. 'The Event' is held every two years and is solely represented by suppliers to the Cromwell Group in the UK.

Approximately 4000 people attended this year’s event, which for the first time was open to the general public. The majority of those that attend are existing or previous customers of Cromwell and they are invited along with their respective branch and sales representative. Attendees also had the opportunity to experience the thrills of the internationally recognised race circuit, with the choice of driver experiences in several high powered sports cars. Those looking for something a little slower paced but no less exciting could choose the off road experience.

The Koyo stand was situated with the MRO sector of the exhibition and we were the only dedicated bearings supplier at the whole event. Koyo UK, supported by JEB showcased the latest offerings from Koyo (JTEKT) and focused on the new JHS BBU & SRB ranges. Along with this we also held a competition to win 'Red Letter Day' vouchers by guessing how many complete bearings were contained with a glass display case on the stand. The winner will be presented with the vouchers in the near future.

During the course of 'The Event' the Koyo stand was visited by around 400 individuals which has led to around 100 requests for further information. Some of these were very positive and have requested joint visits with the local Cromwell branch & representative. Koyo UK will look to follow these up as quickly as possible.

The show was a great success and will hopefully lead to increased business and improved relations with Cromwell and their customer base.

Eğik bilyalı rulman nedir?

Eğik bilyalı rulmanda eksenel asimetrik yuvarlanma yolu vardır. Eksenel yükler rulmanın içinden düz bir şekilde geçmekle beraber, radyal yükler eğik yolla geçmektedir. O eğik yolun, yuvarlanma yolunu eksenel bir şekilde ayırmaya eğilimi vardır. Böylece, hem diş hem de iç yuvarlanma yolların temas açışı aynıdır. Eğik rulmanlar birleşmiş yüklerle birlikte (hem radyal hem de eksenel yönlü) daha iyi çalışmakta. Rulmanın temas açısı ise verilen yüklerin miktarlarına uyumlu olmalıdır. Temas açısı arttıkça (standart olarak 10 ve 45 derece arasındadır) rulmanın da eksenel yüke karşı direncı artar, fakat aynı zamanda radyal yükleme kapasitesi azalır. Türbin, jet motoru ya da dişcilik aletler gibi yüksek hız uygulamalarda, rulman içindeki bilyalar tarafından oluşturan merkezkaç kuvvetler iç ve dış yuvarlanma yollarındaki temas açısını değiştirmekte. Bu tip uygulamalarda yoğunluğu az olduğu için (çeliğin %40 yoğunluğu) silisyum nitrür gibi seramik maddeler sıkca kullanılmaktadır. Yüksek sıcaklık içinde çok iyi çalışıp, merkeckaç kuvveti oldukça azaltır. Onlar rulman çeliği gibi aşınıyor, o yüzden çatlama ya da kırma çok az karşılanan bir durum. Eğik bilyalı rulmanlar çoğu bisikletlerde, esasen onların direksiyon rulmanında kullanılır, çünkü onları hem radyal hem de eksenel yükler etkilemektedir.
