Below is a sample comparison of electricity cost between an air cylinder application and a ROBO Cylinder application. In this example, the air cylinder and ROBO Cylinder are assumed to have the same ratings and carry out the same operation.

Sample Comparison of Electricity Costs (Annual Running Cost)


(1) Rod-less (Slide Type)

* The air cylinder specifications (inner cylinder diameter, etc.) and ROBO Cylinder specifications (motor wattage, motor characteristics, etc.) may slightly vary slightly depending on the models selected for the operation. The specific level of power consumption changes according to the specifications (characteristics) of each model, conditions in which the model is used, etc.

Comparison Model Rodless Air Cylinder/Slide Type ROBO Cylinder/RCP3, Slider Type (RCP3-SA3C-I-28P-6-300-P1-S)
Specifications • Inner cylinder diameter: 10mm
• Stroke: 300mm
• 24-VDC pulse motor
• Stroke: 300mm
Operation Conditions Transfer loads between processes (Horizontal movement of the slider)
• Load: 1kg
• Stroke Length: 300mm
• Cycle Time: 3 sec
• Operating Hours: 16 hours/day, 240 days/year
Service Pressure: 0.4 MPa - N/A
Air Consumption (annual) 1,085.18 Nm³ - N/A
Power Consumption (annual) 116.61 kwh 33.59 kwh
Electricity Charge (annual) (1 Nm3 = $0.013) (1 kwh = $0.121) $14.11 $4.06
Calculation Formula "Air consumption per cycle" x "Number of operation cycles" x "Unit energy cost of air" 0.0002355 Nm³ x 19,200 cycles/day x 240 days x $0.013/Nm³ = $14.11/year "Air/electricity consumption per cycle" x "Number of operation cycles" x "Unit energy cost of electricity" 0.00000729 kwh x 19,200 cycles/day x 240 days x $0.121/kwh = $4.06/year
Result The running cost of the ROBO Cylinder is approximately 30% of the corresponding cost of the air cylinder (reduction of approximately 70%)
CO2 reduction: 0.0307 ton/year (CO2 reduction ratio: 70%) (The equivalent CO2 emissions and effect of reduction vary depending on the specifications of the entire system)

*Calculated exchange rate: 1 USD = 100 JPY (10/08)

(2) Rod Type

Comparison Model Rod Type Air Cylinder ROBO Cylinder/ERC2, Rod Type (ERC2-RA6C-I-PM-3-50NP-S)
Specification - Inner cylinder diameter: 40mm
- Stroke: 50mm
- 24-VDC Pulse Motor
- Stroke: 50mm
Operation Conditions Transfer loads between processes (Horizontal movement of the rod)
- Load: 1kg
- Travel: 50mm
- Cycle Time: 3 sec
- Operating hours: 16 hours/day, 240 days/year
- Service Pressure: 0.4 MPa - N/A
Air Consumption (annual) 2662.32 Nm3 - N/A
Power Consumption (annual) 280.03 kwh 68.25 kwh
Electricity Charge (annual) (1 Nm3 = $0.013) (1 kwh = $0.121) $34.61 $8.26
Calculation Formula "Air consumption per cycle" x "Number of operation cycles" x "Unit energy cost of air" 0.000577776 Nm3 x 19,200 cycles/day x 240 days x $0.013/Nm3 = $34.61/year "Electricity consumption per cycle" x "Number of operation cycles" x "Unit energy cost of electricity" 0.00001481 kwh x 19,200 cycles/day x 240 days x $0.121/kwh = $8.26/year
Result The running cost of the ROBO Cylinder is approximately 24% of the corresponding cost of the air cylinder (reduction of approximately 76%)

CO2 reduction: 0.0805 ton/year (CO2 reduction ratio: 76%) (The equivalent CO2 emissions and effect of reduction vary depending on the specifications of the entire system)

*Calculated exchange rate: 1 USD = 100 JPY (10/08)
* The air cylinder specifications (inner cylinder diameter, etc.) and ROBO Cylinder specifications (motor wattage, motor characteristics, etc.) vary depending on the models selected for the operation. The specific level of power consumption changes according to the specifications (characteristics) of each model, conditions in which the model is used, etc.
