What Are Deep Groove Ball Bearings?
Deep groove ball bearings are the most common type of rolling element bearings, featuring simple design, ease of use, and wide applicability. They primarily support radial loads and can also accommodate certain axial loads.
Key Advantages of Deep Groove Ball Bearings
- Low Friction - Smooth operation with low noise, ideal for high-speed applications
- High Precision - Especially P4 and P5 grade bearings for precision equipment
- Easy Maintenance - Sealed (2RS) bearings are maintenance-free with extended service life
- Cost-Effective - Excellent value for high-volume applications
How to Select the Right Deep Groove Ball Bearing
1. Determine Size Specifications
Select the appropriate bore diameter based on your shaft size. Common series include:
- 6200 Series - Light duty, suitable for small motors
- 6300 Series - Medium duty, highly versatile
- 6400 Series - Heavy duty, higher load capacity
2. Choose Seal Type
- Open Type - Suitable for clean environments, requires regular lubrication
- Shield (Z/ZZ) - Basic dust protection
- Rubber Seal (RS/2RS) - Best sealing performance, ideal for harsh environments
3. Consider Precision Grade
- P0 (Standard) - General industrial applications
- P6 - Applications requiring higher precision
- P5/P4 - High-precision applications such as machine tool spindles and EV motors
Common Applications
- Electric motors and generators
- Automotive transmissions and wheel hubs
- Household appliances (washing machines, air conditioners)
- Industrial pumps and fans
- Agricultural machinery
