Type | Description | Applications |
---|---|---|
Radial | Supports perpendicular loads | Gearboxes, shafts |
Thrust | Supports axial loads | Pumps, compressors |
Combination | Hybrid design for both radial and axial loads | Actuators, power tools |
Ball | Uses spherical rolling elements | High load capacity, low friction |
Roller | Uses cylindrical or conical rolling elements | High load capacity, moderate friction |
Needle | Uses thin, cylindrical rolling elements | High load capacity in confined spaces |
Load | Definition | Units |
---|---|---|
Static load rating | Maximum constant load a bearing can support without permanent deformation | N |
Dynamic load rating | Maximum load a bearing can support for a given number of revolutions and operating life | N |
Fatigue load rating | Maximum load a bearing can withstand for a given number of stress cycles | N |
Cause | Description | Prevention |
---|---|---|
Overloading | Excessive load on the bearing | Use bearings with appropriate load capacity |
Improper lubrication | Inadequate or incorrect lubrication | Follow manufacturer's recommendations for lubrication |
Misalignment | Shaft or gear misalignment | Ensure proper alignment during installation |
Contamination | Dirt or debris entering the bearing | Use seals and shields to protect from contamination |
Wear | Gradual wear due to friction and repeated loading | Use high-quality bearings with proper lubrication |
Corrosion | Exposure to corrosive environments | Use bearings with corrosion-resistant coatings |
