| Torque Savings with Enhanced Product = (2 * 4.0 N-m) - (2 * 3.0 N-m) = 2.0 N-m |
| Energy Consumption (Q =k*N*M) = .105*3000 RPM * 2.0 N-m = 630 W = .640 KW |
| Lifetime Energy Consumption = .630 KW * (24 hrs/day * 365 days/yr * 5 years) = 27,594 KW = 27.6 MWh |

(10,670 kg CO2)
Pump Application
- Bearing efficiency increases by 10% (current vs. enhanced)
- Current bearings = 3.0 N-m torque each, Enhanced Bearings = 2.7 N-m torque each
- Two tapered roller bearings supporting the pump shaft
- Pump driven by an electric motor operating at 1800 RPM
- Operational Time of Consideration: 5 years

Geardrive Application
- Bearing efficiency increases by 10% (current vs. enhanced)
- Current bearings = 6.6 N-m torque each, Enhanced Bearings = 6.0 N-m torque each
- Two tapered roller bearings per shaft x 3 shafts = 6 total bearings
- Gearbox driven by an electric motor operating at 1800 RPM
- Operational Time of Consideration: 5 years
- Customer Location: USA
- $0.17 KWh (based on US average)
