About the Airtac SC100 Standard Cylinder SC100X640
The AirTAC SC100X640 is a double-acting tie-rod cylinder delivering a substantial push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. Its 100 mm bore and 640 mm stroke suit medium-to-long linear actuation tasks, with a 25 mm diameter piston rod providing robust guidance.
This model features a body length A of 188 mm and an adjustable air cushion length of 29 mm to decelerate the piston smoothly at stroke end. The standard PT1/2 port and M20x1.5 rod thread ensure straightforward pneumatic connections, while the TPU seals offer reliable operation from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X640 Is Used
Pallet Transfer
Moves heavy pallets across roller conveyors in distribution centers, leveraging 3927 N of push force at 0.5 MPa for reliable shifting.
Press-Fit Assembly
Provides the controlled 7068 N force at 0.9 MPa needed for pressing bearings or bushings into large housings on an assembly line.
Product Diverting
Actuates a diverter gate on a wide conveyor, using the 640 mm stroke to sweep products onto a secondary line.
Is the Airtac SC100 Standard Cylinder SC100X640 the Right Cylinder?
Select the SC100X640 when your application needs around 4000 N of push force at standard plant pressure. If your load is lighter, stepping down to the 80 mm bore (2513 N push at 0.5 MPa) can reduce air consumption. For heavier demands, the 125 mm bore provides 6136 N at the same pressure. With a 640 mm stroke, ensure the load is guided externally if side forces are present, as the 25 mm rod can bend under unsupported lateral loads.
To replace this cylinder directly, match five key points: 100 mm bore, 640 mm stroke, PT1/2 port thread, basic mount (no accessory bracket), and a non-magnetic piston. An ISO 15552 cylinder will not be a dimensional match, as the SC tie-rod series has a shorter body length.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC100 Standard Cylinder SC100X640 FAQ
At 0.7 MPa operating pressure, the SC100X640 double-acting cylinder generates a push force of 5497 N. The maximum push force at 0.9 MPa is 7068 N.
No, the SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC100 tie-rod cylinder matching the 640 mm stroke, PT1/2 ports, and basic mounting.
