About the Airtac SC100 Standard Cylinder SC100X640SH
The SC100X640SH is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 640 mm stroke suits medium-reach material handling, pressing, and clamping operations where high force and heat resistance are required.
This model features a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm adjustable air cushion at each end to decelerate the load smoothly. The 'S' suffix denotes a built-in magnet, allowing CMSG/DMSG/EMSG sensors to be mounted directly on the tie-rod barrel for contactless position sensing. The 'H' suffix upgrades the seals to Viton (FKM), shifting the operating temperature range to 0–150 °C for hot or chemically aggressive environments.

Where the Airtac SC100 Standard Cylinder SC100X640SH Is Used
Foundry & Heat-Treat Clamping
Viton seals withstand ambient temperatures up to 150°C, making this cylinder suitable for clamping hot workpieces in foundries, welding fixtures, or heat-treatment lines.
High-Force Part Transfer
With 3927 N of push force at 0.5 MPa, it reliably transfers heavy castings or fabrications along roller conveyors, with sensor magnets confirming end-of-stroke position.
Hot-Melt Pressing
The 640 mm stroke and high-temperature seals support platen actuation in hot-melt laminating or composite forming presses where standard seals would degrade.
Is the Airtac SC100 Standard Cylinder SC100X640SH the Right Cylinder?
For applications needing slightly less force, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If the 640 mm stroke generates high side-load moments, consider an external linear guide or a guided cylinder to protect the rod bearing from bending stress, especially with the 25 mm rod fully extended.
When replacing this cylinder, match five key points: 100 mm bore, 640 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal (-H). The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 of the same 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 SC100X640SH FAQ
At 0.7 MPa supply pressure, the 100 mm bore SC cylinder generates 5497 N of push force and 3681 N of pull force on the retract stroke, based on the official AirTAC thrust table.
No. The SC100X640SH is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
