📋 How to Select the Right Metallurgy & Mine Bearing?
1. Load Type & Magnitude
- Heavy shock loads → Spherical roller bearings
- Combined radial/axial → Tapered roller bearings
- High radial loads → Cylindrical roller bearings
2. Operating Environment
- High dust / debris → 2RS sealed design
- High temperature → Special heat stabilization
- Corrosive → Stainless steel or coated rings
3. Speed & Misalignment
- High speed → Precision grade P5 / P6
- Shaft misalignment → Self-aligning designs
- Low speed / high torque → Full complement rollers
