About the Airtac SC100 Standard Cylinder SC100X900H
The SC100X900H is a 100 mm bore, 900 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. With a 25 mm diameter piston rod, M20x1.5 rod thread, and PT1/2 ports, this cylinder generates a push force of 3927 N at 0.5 MPa and reaches 7068 N at the maximum operating pressure of 0.9 MPa.
Designed for demanding thermal applications, the SC100X900H features an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 1088 mm. This model is a basic configuration without a magnet or mounting accessories, allowing you to add the specific brackets your application requires.

Where the Airtac SC100 Standard Cylinder SC100X900H Is Used
High-Temperature Process Automation
The Viton seals allow this 100 mm bore cylinder to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach 150 °C, providing consistent 3927 N actuation force.
Long-Stroke Material Transfer
With a 900 mm stroke and 7068 N of force at 0.9 MPa, this cylinder is ideal for transferring heavy parts between stations in manufacturing cells, especially where heat is a byproduct of the process.
Hot Mold Ejection Systems
Deploy the SC100X900H for ejector plates in plastic injection or die-casting molds. The high-temperature Viton seals withstand mold heat, and the adjustable cushion protects the mold from impact damage.
Is the Airtac SC100 Standard Cylinder SC100X900H the Right Cylinder?
Select the SC100X900H when your application needs a 900 mm stroke with high-temperature resistance. If the 3927 N push force at 0.5 MPa exceeds your requirement, stepping down to an 80 mm bore reduces the force to 2513 N. For higher force needs, the 125 mm bore provides 6136 N. Always match replacements across five key points: bore (100 mm), stroke (900 mm), PT port thread, Viton seal material, and the basic mounting configuration.
For this 900 mm stroke length, carefully evaluate side-loading conditions. An unsupported 25 mm rod extended nearly a meter is susceptible to bending under lateral forces. Use an external linear guide or a guided cylinder configuration to protect the rod bearing and ensure long service life.
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 SC100X900H FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X900H is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or drop under load. For load-holding applications, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
