In response to the strong expansion of battery electric vehicle (BEV) market, JTEKT has developed “JTEKT Ultra Compact Bearing. (JUCB)”, as ball bearing for BEV eAxle. JUCB is extremely small compared with conventional bearing for the same diameter.
Shortened unit length, while maintaining the strength and durability of bearings
The bearing performance such as strength and durability is the same as that of conventional products, and the bearing width has been narrowed to the limit. By applying it to the general-purpose size “6207”, the axial dimension is shortened by 5 mm (about 30%) and the weight is reduced by 73 g (about 26%). As a result, JUCB has made it possible to shorten the unit length of coaxial eAxle and 3-axis eAxle.
JUCB is applicable not only to BEV eAxles, but also to industrial machinery such as construction machinery, agricultural machinery, robots, and drones. We will meet the needs for miniaturization of all types of drive systems.
