Aiming at the anti-friction technology in bearing development, the technical characteristics of the low friction series tapered roller bearings from the five major foreign bearing companies were introduced and summarized. The research status of domestic related technologies were described and compared with foreign technologies. The results show that domestic research on bearing antifriction technology is insufficient, and product development of anti-friction tapered roller bearings needs to be strengthened. The discussion on antifriction technology can provide reference for domestic bearing development.
