Two bearings per axle x 4 axles per freight wagon x 100 freight
wagons per train = 800 bearings per train
Operational Time of Consideration: 5 years²
Customer Location: USA
Loco fuel consumption: 0.028 MWh/Gal³
Electricity Price: $0.13/kWh⁴
CO2 emissions: 10.18 kg CO2 per gallon

Based on torque differential per Bearing of 20 in. lbs
Assuming 5 years average wheel life
Assuming Tier 4 CO line-haul emission factors and large line-haul and passenger conversion factor
Estimation based on U.S. electricity retail price by sector 2024

Calculations
Energy Savings per Bearing: 155 W = 0.155 kW
Lifetime Energy Consumption per Wheel Life: 0.155 kW * 1143h * /a * 800 bearings / train * 5a = 708 MWh
Energy cost Savings per Train Wheel Life: 708 MHh * $130 MwH = $92,000 saved
Emissions Savings per Train Wheel Life: 708 MWh * 10.18 kg CO2/gal * 35.7 gal/MWh * 0.001 ton/kg

Application: Passenger Trains

Bearing efficiency increases by 25% (current vs. enhanced)
- Current bearings (A) = 319W each
- Enhanced bearings (B) = 205W each
Two bearings per shaft x 4 shafts per car x 6 cars per vehicle x 10
vehicles per fleet = 480 bearings

Calculations
Energy Savings per bearing: (PA-PB) 114 W = 0.114 kW
Lifetime Energy Consumption for a Fleet of 10 Vehicles: 0.114 kW * 2930h /a * 48 bearing / vehicle * 10 vehicles * 30a = 4810 MWh
Lifetime Energy Consumption: 4810 MWh * $142/MWh = $682k

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