About the Airtac SC100 Standard Cylinder SC100X640S
The AirTAC SC100X640S is a double-acting pneumatic cylinder with a 100 mm bore and a 640 mm stroke, delivering a push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 29 mm adjustable air cushion provide reliable deceleration for mid-to-heavy linear motion tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The standard PT1/2 port thread and TPU seals make it suitable for general industrial environments within a -20 to +70 °C temperature range.

Where the Airtac SC100 Standard Cylinder SC100X640S Is Used
Material Transfer Gates
The 640 mm stroke and 3927 N push force at 0.5 MPa effectively operate diverter gates on wide conveyor lines, reliably pushing products onto parallel tracks.
Heavy Part Clamping
With a 25 mm rod and up to 7068 N of force at 0.9 MPa, this cylinder provides the high clamping pressure needed to secure large weldments or castings during machining.
Pallet Stop Positioning
The built-in magnet supports CMSG/DMSG sensors to confirm full retraction and extension, making it ideal for end-of-line pallet stops where positive position feedback is required.
Is the Airtac SC100 Standard Cylinder SC100X640S the Right Cylinder?
Select the SC100 bore when your application requires a push force between 3927 N (at 0.5 MPa) and 7068 N (at 0.9 MPa). If the load is lighter, stepping down to an SC80 bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the SC125 bore offers 6136 N at the same 0.5 MPa pressure.
For this 640 mm stroke, ensure the load is guided and free from significant side forces. Long, unsupported strokes on a single rod can create a bending moment on the rod bearing; use an external guide rail or a guided cylinder if side loads are present. When replacing an existing unit, match these five points: 100 mm bore, 640 mm stroke, PT1/2 port thread, the built-in magnet for sensors, and the basic (footless) mounting configuration.
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 SC100X640S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
Yes. The -S suffix in the model code SC100X640S indicates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
