Miniature Bearing

BCHH Miniature Bearings exemplify precision engineering on a micro scale, drawing upon our 20+ years of

 specialized manufacturing experience and ISO 9001 certified quality systems. These ultra-compact deep 

groove ball bearings are produced with tolerances as tight as ABEC 7/P6, utilizing high-purity chrome steel, 

stainless steel, or ceramic materials. Despite their small size - with bore diameters from 1mm - they 

maintain exceptional rotational accuracy, low noise, and reliable performance in high-speed applications, 

making them ideal for the most demanding precision instruments and compact mechanisms.

Applications:

Precision medical devices and dental handpieces

Small DC motors and micro-motors

Robotics and drone propulsion systems

Optical instruments and encoders

Computer disk drives and office automation equipment

Aerospace instrumentation and guidance systems
