The 6702 ZZ is a deep groove ball bearing, finds its applications across various fields due to its thin-section design (dimensions 15×21×4mm), high precision, and other notable features. Here are the primary application areas:
1. Beauty Instruments and Personal Care Devices
Primarily used in the rotating components of automatic hair curlers, foot files, and similar products. Its thin-wall design and high-precision characteristics make it suitable for miniaturized devices operating under high temperatures or at high speeds.
2. Smart Automation and Robotics
Applied in precision transmission systems such as smart locks, robot joints, and robotic arms. The low noise, high speed (up to 7600rpm with grease lubrication), and stability of this bearing make it ideal for these applications.
3. Motors and Micro Machinery
Suitable for use in micro motors, model aircraft, cooling fans, etc. The double-sided dust cover (ZZ) design effectively prevents dust ingress, extending the lifespan of the bearing.
4. Automotive and Industrial Equipment
Utilized in auxiliary components of automotive engines, gearboxes, machine tool gearboxes, reducers, etc. Made from high-carbon chromium bearing steel (GCr15), it supports operations in high-temperature environments and offers strong axial load capacity.
5. Home Appliances and Office Equipment
Commonly found in oscillating fans, shredders, printers, and more. Its low vibration characteristic contributes to smoother operation of these devices.
6.Other Potential Applications
Also involved in medical devices, precision instruments, and other sectors that require high precision and reliability.
