Product Features
The ends of the needle rollers used in automotive electric components are crowned (i.e. given a curved arc) to make the bearings able to withstand a heavy load
Improved roundness of the roller crowning compared to the conventional product through developing a high-precision machining method
Benefits
The noise level (sound pressure) generated by the bearing was reduced to one third of that of the conventional product
The product will help create more silent, comfortable vehicle interiors in EVs, HEVs, and luxury cars where a very quiet ride is required
