Rotor bearings are critical components in rotating machinery, responsible for supporting the rotor and minimizing friction between the rotating and stationary parts. They play a vital role in ensuring the longevity, efficiency, and safety of industrial equipment.
Bearing Type | Advantages | Disadvantages |
---|---|---|
Rolling-Element Bearings | High load capacity, low friction | Expensive, sensitive to contamination |
Sleeve Bearings | Simple design, low cost | High friction, limited load capacity |
Hydrostatic Bearings | Zero friction, high precision | Complex design, high maintenance |
Bearing Material | Properties | Applications |
---|---|---|
Steel | High strength, wear-resistant | Rolling-element bearings |
Bronze | Anti-friction, corrosion-resistant | Sleeve bearings |
Polymer | Low friction, low cost | Hydrostatic bearings |
