    MYONIC / GRW Bearings for Dental Micromotors Handpiece
    High RPM micro motor bearings, often ceramic (hybrid) or SUS440C stainless steel, are essential for speeds exceeding 50,000–300,000+ RPM in applications like dental handpieces, dental lab motors, and precision tools. Common sizes include 830, 940, 1260, and 1480, which are often used in Strong Korea/Seashin tools. These bearings require precision ABEC-9 quality to ensure minimal vibration and long life. 
    This video shows how to replace the bearings in a micro motor handpiece:
