A roller bearing design is never "final". Even after installation into a machine or device, it may behave differently than expected based on earlier tests, calculations and simulations. Therefore constant engineering support to users is a must for a top bearing manufacturer. Here is an interesting case study .

After the merger of Koyo Seiko and Toyoda Machine Works in 2006 to form JTEKT Corporation, engineers from both divisions have worked closely together to develop state of the art spindle shaft support bearings, which are key to modern machine tools with high accuracy & precision requirements.

Avoiding "bearing creep" is an underestimated challenge when designing the proper roller bearing for certain applications. Bearing creep happens when the outer rings moves relative to the housing in which it is mounted. Simply applying a light press fit seems easier than it practically is and may cause other functional problems. Therefore Koyo has been developing more suitable anti-creep solutions which are described in our latest article in BearingNews:

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. Любая девушка может снять красивый секс

Konik makaralı rulman, diş ve iç bilezik arasında konik makaraları (kesik koni şeklinde) olan bir rulman türüdür. Iç bileziğin arkasında olan kaburga, makaraların yönlendirilmesini sağlamaktadır.
Alçak ve orta hızlara kadar yüksek radyal ve eksenel yük kapasitesi vardır. Konik makaralı rulmanların bir, iki ve dört sıralı versiyonları mevcuttur. Tek sıralı rulmanda, eksenel yük taşıma kapasitesi radyal yük taşıma kapasitesinin %60 kadarıdır. Iki sıralı rulmanların radyal yük kapasitesi, ayrıca iki yönde çalışan şok yüklere karşı kapasitesi de daha iyidir. Makaraları, yuvarlanma yolları dokunma çizgiyle dönme eksenine göre uyumlu veya uyumsuz şekilde olması için yerleştirilebilmekte. İki sıralı uyumsuz rulmanlar milin sertliğini yükseltmekle beraber, uyumlu olan öyle özelliği göstermemekte. Başka düzenlemede iki sıralı rulmanların ya tek dış ve iki iç bileziği ya da iki dış ve tek iç bileziği mevcuttur. Dört sıralı konik makaralı rulmanlar, dört değişimli olarak yerleşmiş, uyumlu ve uyumsuz makarlardan ibarettir.
