The 6701 deep groove ball bearing is widely used across various
specialized fields due to its compact size and high precision.
Application areas include:
1. Industrial Machinery and Manufacturing Equipment:
Used in industrial scenarios such as rubber machinery, laser
cutting machines, heat shrink packaging machines, painting
production lines, and smelting equipment, especially suitable for
devices requiring high speed and lightweight design.
Plays a critical role in transmission functions within CNC
machinery, textile machinery, welding machines, and steel bar
drawing machines.
2. Power Tools and Small Equipment:
Commonly found in power tools (such as handheld drills, grinders)
and small gearboxes, precision instruments. Its thin-section design
(thickness ranging from 2.7 to 4mm) makes it ideal for compact
spaces.
3. Automotive and Automation Fields:
Utilized in automotive components like steering systems, braking
systems, and gearboxes. Also suitable for industrial automation
equipment, robot joints, and hydraulic transmission systems.
4. Home Appliances and Daily Life Equipment:
Widely applied in washing machines, air conditioner compressors,
and food processing machinery (such as heat presses, ironing
machines).
