The 679 ZZ miniature deep groove ball bearing is widely used across various specialized fields due to its compact size and high precision. Application areas include:

I. Industrial Equipment

Motors and Power Tools

Suitable for use in miniature motors and power tools (such as drills, angle grinders), benefiting from its high-speed performance (with speeds up to 36,000-42,000 rpm) and low friction characteristics.

Automation Machinery

Utilized in light industrial automation equipment (like packaging machines, textile machinery). Its high precision (P0 tolerance grade) and low noise features enhance the stability of these devices.

II. Consumer Electronics

Home Appliances

Commonly found in motor components of household appliances such as fans, vacuum cleaners, and washing machines. The sealed structure prevents dust intrusion, thereby extending the lifespan of the bearing.

Sports Equipment

Applied in the wheel axles of sports gear like roller skates and hoverboards. The thin-wall design (only 4.5mm thick) fits well into compact spaces.

III. Precision Instruments

Medical Equipment

Used in dental instruments and laboratory equipment.  

Office Equipment

Essential for the transmission components of printers and copiers, relying on their low starting torque and sealed dust-proof performance.
