Type | Construction | Advantages | Applications |
---|---|---|---|
Deep Groove Ball Bearings | Deep, uninterrupted raceways | High radial load capacity, moderate axial load capacity | Automotive engines, transmissions, pumps |
Angular Contact Ball Bearings | Angled raceways | High thrust load capacity, moderate radial load capacity | Machine tools, spindle bearings, aerospace components |
Self-Aligning Ball Bearings | Spherical outer ring | Compensates for misalignment, high radial load capacity | Conveyors, agricultural machinery, medical equipment |
Factor | Description |
---|---|
Load Capacity | The bearing must be able to withstand the expected radial and axial loads. |
Speed | The operating speed should be within the bearing's specified limits. |
Lubrication | The bearing must be compatible with the available lubrication method. |
Environment | Operating temperature, contamination, and vibration can affect bearing performance. |
Mistake | Consequences |
---|---|
Improper Lubrication | Premature wear, shortened lifespan |
Overloading | Bearing failure |
Misalignment | Excessive stress, reduced bearing life |
Contamination | Damage to bearing surfaces |
