About the Airtac SC100 Standard Cylinder SC100X300H
The SC100X300H is a double-acting pneumatic cylinder with a 100 mm bore and 300 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. At a standard 0.5 MPa air supply, it generates a push force of 3927 N and a pull force of 3681 N, making it a strong actuator for heated industrial processes.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 rod thread and PT1/2 ports. The adjustable air cushion at each end is 29 mm long, and the total extended body length is approximately 488 mm. The 300 mm stroke is within the standard range for the 100 mm bore, ensuring quick availability from genuine AirTAC stock.

Where the Airtac SC100 Standard Cylinder SC100X300H Is Used
High-Temperature Process Actuation
With Viton seals rated for 0 to 150 °C, this cylinder is ideal for clamping, pressing, or ejecting parts in autoclaves, drying ovens, and hot-forming stations where standard seals would degrade.
Heavy-Duty Material Handling
The 3927 N push force at 0.5 MPa allows the SC100X300H to lift, shift, or position heavy components on heat-assisted assembly lines, such as engine block transfer or glass panel handling.
Hot Press & Lamination
Delivers consistent clamping pressure for heat-activated adhesives or composite lamination processes. The adjustable cushioning ensures smooth, impact-free motion when closing heated platens.
Is the Airtac SC100 Standard Cylinder SC100X300H the Right Cylinder?
Choose the SC100X300H when your application demands a high-force actuator that can withstand ambient or media temperatures from 0 to 150 °C. If 3927 N of push force at 0.5 MPa exceeds your requirement, consider stepping down to the 80 mm bore (2513 N push), which offers a smaller footprint. For even higher force at the same pressure, the 125 mm bore provides 6136 N push.
At a 300 mm stroke, the 25 mm rod has good column strength, but any significant side loading still requires an external guide or a guided cylinder to prevent rod bearing wear and bending. For a direct replacement, match the 100 mm bore, 300 mm stroke, PT1/2 ports, basic mounting, and ensure the seal material is Viton (H) for high-temperature compatibility.
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 SC100X300H FAQ
At 0.5 MPa, the cylinder provides 3927 N pushing force and 3681 N pulling force. 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.
Yes, the 'H' suffix designates Viton (FKM) seals, which shift the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. It is a direct dimensional replacement for an SC100X300 with PT ports and basic mounting, but you must verify that all external components (sensors, tubing, fittings) are also rated for the higher temperature.
