"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.

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!

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.
Spherical roller bearings feature a large load rating and self-aligning capability. This type of bearing is suitable for low- or medium speed applications which involve heavy or impact loading. Spherical roller bearings are self-aligning, double-row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element. The outer ring contains a spherical race which allows for some misalignment of the shaft and housing. Spherical roller bearings are unequalled in their capacity for high loads and tolerance to shock loads, but have limited speed capabilities. They perform consistently, even under conditions of extreme speed, application-specific stress, and marginal lubrication. The cage of a spherical roller bearing provides high dimensional accuracy and functionality. According to some estimates, spherical roller bearings have twice the running life of conventional bearings.
