⚙️ Types of Ball Bearings and Their Model Series ⚙️
Ball bearings are one of the most essential machine elements that reduce friction, support loads, and enhance efficiency across industries.
🔹 Introduction to Ball Bearings
Ball bearings are rolling element bearings that use balls to separate races. They can handle both radial and axial loads, making them vital in machinery.
🔧 Major Types of Ball Bearings
⚡ 1. Deep Groove Ball Bearings
Most widely used for radial + light axial loads. Common in motors, pumps, appliances.
⚡ 2. Angular Contact Ball Bearings
Designed for combined loads. Used in turbines, gearboxes, high speed tools.
⚡ 3. Self Aligning Ball Bearings
Two rows of balls + spherical raceway. Compensates for misalignment.
⚡ 4. Thrust Ball Bearings
Handles axial loads only. Used in turntables, cranes, vertical shafts.
⚡ 5. Miniature & Instrument Bearings
Small size, high precision. Used in robotics, dental tools, instruments.
🌟 Comparison Table
| Type | Load | Series | Applications |
| Deep Groove | Radial + Light Axial | 6000, 6200 | Motors, Pumps |
| Angular Contact | Combined | 7200, 7300 | Turbines, Tools |
| Self-Aligning | Radial + Misalignment | 1200, 2200 | Rollers, Shafts |
| Thrust | Axial Only | 51100, 51200 | Cranes, Turntables |
| Miniature | Light Load | 608, 609 | Robotics, Instruments |
💡 Conclusion
Ball bearings exist in many types and series. Deep groove is versatile, angular contact for speed, self aligning for misalignment, thrust for axial loads, and miniature for precision. Series codes help identify size, load, and design.
