- Lubrication Engineering Protocol
- Oil Viscosity Selection:
- Standard: ISO VG 220 ↔ -10°C to 80°C
- Arctic: ISO VG 68 ↔ -40°C to 65°C
- Tropical: ISO VG 320 ↔ 15°C to 110°C
- Relubrication Formula:
Interval (hrs) = [(14,000,000 / RPM) × (150mm / Bearing Bore)^0.5] - 500
- Vibration Diagnostics

- SEW-Specific Maintenance Checklist
- Thermal Inspection:
- FLIR imaging quarterly (Max temp variance: 12°C across housing)
- Oil Analysis:
- Particle count > ISO 17/14/11 = Oil change required
- Bolt Torque Verification:
- M12 flange bolts: 90 Nm ±5%
- M20 foot mounts: 340 Nm ±3%
- Failure Mode Analysis
