Rail transport is a major form of passenger and freight transport all over the world.

Railway vehicles are exposed to tough continuous use for a very long time, often in harsh conditions. It goes without saying that safety, reliability and fault-free operation is required from any component used for such applications. 

Experience and capabilities

Our high precision and high ability bearings fulfill the requirements of this industry. One of the notable applications of Koyo bearings is the Shinkansen train, the famous high-speed bullet train in Japan which we have supplied with bearings for the motor and transmission.

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.
