JTEKT Bearings (Koyo) continues its efforts to optimize its products for a multitude of applications. Recently a new ultra compact bearing was developed for application in Automotive e-axles, contributing to improved power density of the e-drive system.

E-axles are the unit integrating the electric motor, inverter, reducer and differential and are used for electric vehicles. The e-axle must be as compact and light weighted as possible, to contribute to energy efficiency and increased driving range. Additionally this creates more space in the front of the car which can be used for other purposes (better car streamlining or increasing luggage space). To meet such targets JTEKT developed a ball bearing with reduced width (-30%) and weight (-26%) compared to conventional types. (source: Bearing News, January 16, 2023)
