The 675 ZZ miniature deep groove ball bearing is widely used across various specialized fields due to its compact size and high precision. Application areas include:
1. Precision Instruments and Medical Equipment
Medical Diagnostic Devices: Used in transmission systems of biomedical signal detection instruments such as electromyography (EMG) machines and electrogastrography (EGG) machines.
Laboratory Equipment: Components like sample cups and accessories for testing instruments.
Precision Instrumentation: Applied in precision control scenarios requiring low noise and high speed, such as HVAC tools and vacuum systems.
2. Industrial Machinery and Automation Equipment
Small Industrial Equipment: Micro-transmission components in tapping machines, directional control valves, and electric pumps.
Packaging Machinery and Warehouse Equipment: Lightweight, high-speed rotating structures in packaging machinery and warehouse equipment.
Automation and Robotics: Low-load, high-precision applications such as model toys, 3D printing equipment, and robotic joints.
3. Consumer Electronics and Home Appliances
Micro Motor Applications: Utilized in electric tools (e.g., drills, small appliance motors), cooling fans, etc.
Precision Transmission Systems: Found in smart locks, printers, and other devices requiring precise transmission.
4. Special Industrial Scenarios
Metallurgical Equipment Auxiliary Components: Suitable for environments requiring high temperature resistance or dust protection, such as sensor modules in forklifts.
Additional Features: The dust-proof design (indicated by ZZ, denoting double-sided metal shields) makes it suitable for dusty environments like agricultural machinery or industrial production lines. Its maximum speed can reach 49,000 to 57,000 r/min (with grease/oil lubrication), making it ideal for high-speed micro motors.
This bearing's robust design, combined with its high speed and precision capabilities, ensures reliable performance in diverse fields ranging from medical diagnostics and laboratory equipment to industrial automation and consumer electronics. Its ability to operate effectively in challenging environments further enhances its value across multiple industries.
