About the Airtac SC80 Standard Cylinder SC80X840SH
The SC80X840SH is a double-acting pneumatic cylinder delivering a robust push force of 4523 N at the maximum operating pressure of 0.9 MPa, making it suitable for demanding medium-to-heavy linear motion tasks. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide reliable deceleration, while the total extended body length reaches approximately 1022 mm.
This model is equipped with a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors for precise position feedback. The 'H' suffix specifies Viton (FKM) seals, which shift the operating temperature range to 0 to +150 °C, ideal for hot environments or applications involving aggressive media.

Where the Airtac SC80 Standard Cylinder SC80X840SH Is Used
High-Temperature Actuation
With Viton seals rated for 0 to 150 °C, this cylinder is suited for furnace door operators, autoclave loading systems, or pressing operations in foundries where ambient heat would degrade standard seals.
Long-Stroke Material Transfer
The 840 mm stroke is effective for pushing products across wide conveyor gaps or transferring heavy totes between distant roller beds, with sensor feedback confirming full extension and retraction.
Sensor-Monitored Clamping
The built-in magnet enables precise end-of-stroke detection in automated jigs and welding fixtures, ensuring the 4523 N clamping force is fully applied before a cycle proceeds.
Is the Airtac SC80 Standard Cylinder SC80X840SH the Right Cylinder?
Selecting the correct cylinder involves matching force and stroke requirements. The SC80 provides 2513 N of push force at 0.5 MPa. If your application requires higher force, stepping up to the SC100 bore delivers 3927 N at the same pressure. For lower force needs, the SC63 offers 1559 N. This 840 mm stroke is a long, unsupported extension; ensure the rod is not subjected to significant side loading, or use an external guide rail to prevent bending and premature seal wear. For direct replacement, match the 80 mm bore, 840 mm stroke, PT port thread, built-in magnet (-S), and Viton seals (H).
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 SC80X840SH FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N and the pull force is 3175 N. The maximum push force at 0.9 MPa is 4523 N. These values are theoretical; for dynamic applications, apply a safety factor of 30-50%.
No. The SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It must be replaced with another AirTAC SC80 tie-rod cylinder matching the 840 mm stroke, PT ports, magnet, and Viton seals.
