Single Row Deep Groove Ball Bearings With Filling Slots

What Are Single Row Deep Groove Ball Bearings with Filling Slots?

These specialized ball bearings feature a gap—called a filling slot—on both the inner and outer rings. This structural design allows for the insertion of more steel balls compared to standard deep groove ball bearings, significantly boosting their radial load capacity.

Key Advantages

• Increased Radial Load Capacity: The additional steel balls provide better load distribution, extending service life under radial stress.
• High-Speed Performance: Engineered to operate efficiently at high rotational speeds, ideal for dynamic machinery and motors.
• Interchangeable with SKF: Fully compatible with SKF equivalents, ensuring easy replacement and integration into existing systems.

Limitations

While the design enhances radial performance, it also introduces a limitation: the axial load capacity is relatively low. These bearings are not recommended for applications that involve significant axial forces.

Recommended Alternatives for Axial Loads

For applications requiring greater axial load support, consider the following options:

• Double Row Deep Groove Ball Bearings: Provide higher axial and radial load capacity.
• Angular Contact Ball Bearings: Designed specifically to handle combined axial and radial loads effectively.

Applications

Single row deep groove ball bearings with filling slots are ideal for applications such as electric motors, compressors, gearboxes, and industrial fans—where high radial loads and speed are the primary demands.

Conclusion

If you’re seeking a cost-effective solution for high-speed operations with strong radial performance, these bearings offer a reliable and proven option. Just keep in mind their axial load limitations and consider suitable alternatives when needed.
