KO Compressor bearing positions, speed, heat, lubrication, and load conditions.
Screw Compressor Bearing Selection
Screw Compressor 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
- Screw compressor air ends
- Drive-side positions
- Non-drive positions
- Industrial compressor packages
Operating Conditions
- High speed bearing positions
- Heat and oil cleanliness
- Radial and axial load review
- 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 |
|---|---|---|
| Screw compressor air ends | High speed bearing positions | Model, load rating, bore, cage, clearance, fits, and lubrication |
| Drive-side positions | Heat and oil cleanliness | Open or sealed arrangement, contamination control, speed, and temperature |
| Non-drive positions | Radial and axial load review | 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.
