About the Airtac SC100 Standard Cylinder SC100X70SH
The AirTAC SC100X70SH is a 100 mm bore double-acting tie-rod cylinder delivering 3927 N push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. Its 70 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a compact workhorse for short-throw clamping and positioning tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0–150 °C. The 25 mm diameter piston rod and M20x1.5 rod thread provide robust strength, while the PT3/8 port supplies ample flow for rapid cycling in hot or aggressive environments.

Where the Airtac SC100 Standard Cylinder SC100X70SH Is Used
Foundry & Heat-Treat Clamping
Viton seals withstand ambient temperatures up to 150 °C, making this cylinder suitable for clamping fixtures near furnaces, die-casting extractors, and heat-treat transfer lines where standard seals would degrade.
Hot Press & Molding Ejection
Delivers 3927 N at 0.5 MPa for ejector pins and core pulls in heated compression molds. The built-in magnet enables end-of-stroke sensing without brackets in confined, hot tooling spaces.
High-Temp Diverter Gate
Actuates diverter gates on conveyors carrying hot materials. The 70 mm stroke provides a crisp, short-throw motion, while the FKM seals maintain sealing integrity despite continuous exposure to elevated radiant heat.
Is the Airtac SC100 Standard Cylinder SC100X70SH the Right Cylinder?
Choose the SC100X70SH when you need 3927 N at 0.5 MPa with high-temperature tolerance. If your force requirement is lower, the 80 mm bore SC80 series provides 2513 N at the same pressure, potentially reducing air consumption. For higher forces, the 125 mm bore delivers 6136 N at 0.5 MPa. Ensure a proper replacement match by verifying the 100 mm bore, 70 mm stroke, PT3/8 port thread, built-in magnet, and Viton seal material—these five points guarantee drop-in compatibility with an existing AirTAC SC100 tie-rod cylinder.
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 SC100X70SH FAQ
At 0.5 MPa (5 bar) the push force is 3927 N, and at 0.7 MPa (7 bar) it is 5497 N. The maximum operating push force at 0.9 MPa is 7068 N. The theoretical pull force at 0.5 MPa is 3681 N, accounting for the 25 mm rod area.
Yes, provided five key specs match: 100 mm bore, 70 mm stroke, PT3/8 pneumatic ports, a built-in magnet for sensors, and Viton (FKM) seals for high-temperature operation. Always confirm the mounting style—this is a basic body without brackets, so you may need to reuse or order mounting accessories like foot (LB) or flange (FA/FB) kits separately.
