    첫댓글 이번에 7nm 반도체 쇼크도 보면 중국의 기술 축적 현황과 집요함을 너무 만만히 보고 있는 것 같아 걱정입니다. 칭화대 라인에서 EUV를 넘어서는 X선 차세대 노광기를 개발하고 있다고 하는데 "절대" 못한다고 믿고 단정하고 있는데......

    지난 4월에 다른 곳에 댓글 달면서 챗GPT에 볼베어링 관련돼 물어본 적이 있었는데, 답변이 이렇게 달렸네요.

    There are several countries that are well-known for producing high-quality ball bearings. Some of the top ball bearing manufacturing countries include Japan, Germany, the United States, and China.

    Japan is widely regarded as a leader in the production of high-precision ball bearings, with companies such as NTN, NSK, and JTEKT leading the way. Germany is also a significant player in the industry, with companies such as SKF, FAG, and Schaeffler Group producing high-quality ball bearings.

    The United States is home to several major ball bearing manufacturers, including Timken, NTN, and SKF. China has also become a significant player in recent years, with companies such as LYC Bearing Corporation and Wafangdian Bearing Group producing high-quality ball bearings.

    Ultimately, the choice of the "best" ball bearing maker may depend on factors such as the specific application, required precision, and budget. It may be beneficial to do further research and consult with experts in the field to determine the most suitable ball bearing manufacturer for a particular application.

    @위종민 생산량 기준 볼베어링 탑 10은 아래 회사들이라고 합니다.

    Here is a list of the top ball bearing manufacturers by production volume based on data from 2020:

    SKF (Sweden)
    Schaeffler Group (Germany)
    NSK (Japan)
    NTN (Japan)
    JTEKT (Japan)
    Timken (USA)
    MinebeaMitsumi (Japan)
    Nachi-Fujikoshi (Japan)
    C&U Group (China)
    Wafangdian Bearing Group (China)
    It's important to note that production volume is not the only factor to consider when evaluating the quality and reliability of ball bearings. Other factors such as precision, durability, and material quality are also important considerations.
