Small deep groove ball bearings (electric vehicle industry)
Product Features
It is a curvature-optimized design that enhances the bearing’s load-carrying capacity.
The seal employs a heavy-contact double-lip design, providing water resistance.
This waterproof bearing solution is also widely used in applications where water vapor may ingress, such as automobiles, oil pumps, water pumps, and chemical pumps.
Product Applications
Car
Oil pump
Water pump
Chemical pump
It employs a “human”-shaped high-contact sealing structure, providing waterproof performance.
Advantages:
1. Suitable for special operating conditions involving water vapor;
2. The inner sealing lip enhances oil retention;
3. Uses imported, reinforced rubber material;
4. High-precision machining of mating surfaces reduces frictional losses.
Drawback: The friction torque may be higher compared to the RS configuration.
Creating value for society through fast, professional, and high-quality service.
