JTEKT introduces new ONI bearing for bicycle wheel application

  

JTEKT Bearings (formerly Koyo Bearings) recently developed a special ceramic wheel bearing for race bicycle application. The performance (extremely low friction while maintaining bearing life) is remarkable and contributed to world-class sport achievements, as can be read in the below linked article in BearingNews.

FAQ

What is a spherical roller bearing?

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.
