Practical realization of the world's first ceramic bearing in 1984 Reliable, corrosive-resistant and suitable for use in solutions

"Are there any bearings that can be used in water?" From this single question, JTEKT began developing a corrosion-resistant bearing. As a result, we commercialized the world's first ceramic bearing in 1984. This case study introduces the beginning of Koyo's reputation as a major ceramic bearing supplier.

80% less uneven rotation! (compared with a planetary gear) A precision reduction gear adopting Koyo bearing technology

A printing machinery manufacturer facing the dilemma of poor printing quality due to uneven rotation of the feed drum. JTEKT's proposal of a traction drive resulted in accomplishment of a precise gear reduction not possible with a planetary gear. If you face issues of uneven rotation, vibration or noise, this case study is a must-read!

A bearing achieving both size reduction and higher capacity (longer life) Contributing to the further enhancement of robot performance!

In order to manufacture robot parts which are compact, lightweight and long-life, the bearing, which is one element part, also needs to be of ultra-high quality offering both a compact size and high capacity. JTEKT applied itself to this challenge and contributed to the development of new robot parts.

Что такое игольчатые роликоподшипники?

Игольчатые роликоподшипники являются подшипником очень компактной конструкции, базирующейся на цилиндрических роликах. Игольчатые роликоподшипники являются привлекательной в финансовом смысле альтернативой в случае применений, нуждающихся в ограниченном до минимума пространстве, будучи предназначенными для выдерживания определенной нагрузки с установленной скоростью. Благодаря своим свойствам они могут оказаться идеальным решением, особенно с учетом своей способности работать на определенном уровне скорости и нагрузки, и в то же время, - подшипниками с самым маленьким поперечным сечением среди всех типов роликоподшипников
