Applications
The 6702 2RS deep groove ball bearing with double-sided rubber seals is widely used across various fields due to its specific design and performance characteristics.
Home Appliances: Used in washing machines, air conditioner pumps, fans, and soy milk makers for quiet operation and dust protection. Also fits into small devices like smart locks.
Industrial Machinery: Suitable for CNC machines, textile equipment, and power tools (drills, grinders) where it handles moderate radial loads at high speeds.
Precision Instruments: Ideal for model aircraft, micro motors, and medical diagnostic devices thanks to its small size (15×21×4mm) and high precision.
Special Environments: Employed in food processing and wastewater treatment equipment, the sealed design prevents contamination.
