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.

FAQ

What is a cylindrical roller bearing?

Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations. This geometry results in low friction and allows for high-speed applications.
