About the Airtac SC80 Standard Cylinder SC80X250SH
The SC80X250SH is an 80 mm bore, 250 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range from the standard -20–70°C to 0–150°C. The PT1/8 port and M20x1.5 rod thread are standard, and the adjustable air cushion (28 mm length) decelerates the piston smoothly at end of travel.

Where the Airtac SC80 Standard Cylinder SC80X250SH Is Used
High-Temperature Automation
Viton seals enable reliable operation in autoclaves, drying ovens, and foundry equipment where ambient temperatures reach up to 150°C, maintaining 2513 N of force at 0.5 MPa.
Hot-Material Handling
The 250 mm stroke positions gates or diverters on conveyors moving hot products. The built-in magnet allows end-of-stroke sensing without brackets that could loosen under thermal cycling.
Sensor-Monitored Pressing
Combine the -S magnet with CMSG sensors for precise piston position feedback in heat-sealing or laminating presses, where the 4523 N force at 0.9 MPa provides ample clamping power.
Is the Airtac SC80 Standard Cylinder SC80X250SH the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If a shorter overall length is required, the 63 mm bore offers 1559 N at the same pressure. For this 250 mm stroke, ensure side loads are minimal or use an external guide, as the tie-rod design relies on the rod bearing to manage bending moments.
To replace an existing SC80X250SH, match five points: 80 mm bore, 250 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material. The basic mounting configuration means no additional brackets are included, so verify your existing mounting style matches.
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 SC80X250SH FAQ
At 0.5 MPa, the cylinder provides 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X250SH is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
