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.









The price increase for Koyo bearings will be effective as of the 1st of April 2020:

   2,9% (flat increase) for all main series

 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.

Czym są łożyska EXSEV marki Koyo?

Łożyska ceramiczne oraz EXSEV zostały stworzone na potrzeby układów eksploatowanych w skrajnie trudnych warunkach otoczenia, z którymi nie radzą sobie łożyska konwencjonalne. Tego typu łożyska pracują w sposób optymalny w ekstremalnych warunkach, na przykład w pomieszczeniach hermetycznych, w próżni, w wysokich temperaturach czy środowiskach korozyjnych i zanieczyszczonych. Już zdołały znaleźć zastosowanie w wielu różnych systemach i najnowocześniejszych technologiach.
