About the Airtac SC80 Standard Cylinder SC80X1200H
The SC80X1200H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a long 1200 mm stroke. It generates a substantial push force of 2513 N at 0.5 MPa and reaches 4523 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for demanding linear tasks.
This model is equipped with Viton (FKM) seals, designated by the 'H' suffix, which shifts the operating temperature range to 0–150 °C, ideal for hot or aggressive environments. The 25 mm diameter piston rod provides robust strength, and the adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends to protect the cylinder and load.

Where the Airtac SC80 Standard Cylinder SC80X1200H Is Used
High-Temp Material Transfer
Operates reliably in ovens or near heat sources up to 150°C, pushing heavy pallets or products across a conveyor transfer station with 2513 N of force.
Hot Press Actuation
Provides the 4523 N clamping force needed for a heated laminating or forming press, where standard seals would degrade, ensuring consistent cycle times.
Foundry Equipment Positioning
Withstands radiant heat in foundry applications to position a damper or gate, its 25 mm rod and Viton seals maintaining integrity in aggressive thermal conditions.
Is the Airtac SC80 Standard Cylinder SC80X1200H the Right Cylinder?
For applications needing slightly less force, stepping down to a 63 mm bore (1559 N push at 0.5 MPa) can reduce air consumption. If more force is required, the 100 mm bore model offers 3927 N at the same pressure. At this 1200 mm stroke, the long unsupported rod is susceptible to bending under side loads; always use an external guide rail or rod-alignment coupler to prevent premature seal and bearing wear. To ensure a correct replacement, match the 80 mm bore, 1200 mm stroke, PT port thread, and confirm the Viton seal material is required for your operating temperature.
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 SC80 Standard Cylinder SC80X1200H FAQ
At the standard factory pressure of 0.5 MPa, the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes, it is strongly recommended. A 1200 mm stroke with an 80 mm bore creates a long lever arm, and side loads can bend the 25 mm rod or damage the rod bearing. Use an external guide rail or a rod-alignment coupler.
