Screw-compressor shaft positions, speed, heat, lubrication, and replacement checks.
Compressors Bearing Selection
Compressors bearing selection starts with the machine position and complete existing designation. Check load direction, speed, temperature, lubrication, contamination, fits, misalignment, and failure history for that position.
Equipment and Bearing Positions
- Natural gas compressors
- Screw compressors
- Piston compressors
- Centrifugal compressors
Operating Conditions
- Speed
- Heat
- Oil lubrication cleanliness
- Lubrication method and cleanliness
- Shaft or housing misalignment
- Speed and temperature range
Failure Risks
- Incorrect fit or clearance can reduce operating clearance and raise bearing temperature.
- Contamination or unsuitable lubrication can damage raceways, rollers, and cages.
- Misalignment, shaft deflection, looseness, or overload can shorten service life.
Configuration Matrix
| Position | Operating condition | Configuration to confirm |
|---|---|---|
| Natural gas compressors | Speed | Model, load rating, bore, cage, clearance, fits, and lubrication |
| Screw compressors | Heat | Open or sealed arrangement, contamination control, speed, and temperature |
| Piston compressors | Oil lubrication cleanliness | Locating/floating role, misalignment, shoulders, mounting, and removal access |
Selection Checks
- Confirm the complete bearing marking, bearing position, shaft and housing arrangement, and locating or floating role.
- Check radial and axial load, speed, temperature, contamination, lubrication, fits, clearance, cage, and misalignment together.
- Include failure history, quantity, destination, required timing, and inspection or compliance files.
