Trend of Technology for Automotive Needle Roller Bearings and Tapered Roller Bearings Contributing to Improvement of Fuel Efficiency

Abstract

In recent years, the electrification of automobiles and the reduction of fuel consumption have been promoted against the background of environmental problems. To reduce power consumption, reduce size and weight, increase speed, and reduce torque for automotive parts various efforts have been made. In this article, we will introduce the technical trends of AT, HV, EV needle roller bearings and and tapered roller bearings that have been introduced in recent years with the keywords of small size, light weight, low torque, high speed and quietness.
