About the Airtac SC80 Standard Cylinder SC80X65SH
The SC80X65SH is an 80 mm bore, 65 mm stroke double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth end-of-stroke deceleration for consistent cycling.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0–150 °C. The body length A is 182 mm, giving a total extended length of approximately 247 mm.

Where the Airtac SC80 Standard Cylinder SC80X65SH Is Used
High-Temperature Actuation
With Viton seals rated for 0–150 °C, the SC80X65SH is suited for autoclave doors, drying ovens, or hot press tooling where standard seals would degrade.
Conveyor Sorting Gate
The 65 mm stroke and 2513 N push force at 0.5 MPa reliably actuates heavy-duty diverter gates on packaging or palletising conveyors, with sensors confirming gate position.
Clamping & Fixturing
Delivers 4523 N of clamping force at 0.9 MPa for CNC weld fixtures or assembly jigs. The built-in magnet enables end-of-stroke sensing for interlocked cycle start.
Is the Airtac SC80 Standard Cylinder SC80X65SH the Right Cylinder?
Choose the SC80 bore when your application needs push force in the 2513 N (0.5 MPa) to 4523 N (0.9 MPa) class. If you require less force, the SC63 bore provides 1559 N at 0.5 MPa; for more force, step up to the SC100 bore at 3927 N at 0.5 MPa. This 65 mm stroke is well within the 1500 mm maximum standard stroke for the 80 bore.
For a correct replacement, match these five points: 80 mm bore, 65 mm stroke, PT port thread (PT3/8), the built-in magnet (-S), and the basic mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X65SH FAQ
At 0.5 MPa (approx. 72.5 psi) the push force is 2513 N. At 0.7 MPa it rises to 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No, the SC80X65SH is a double-acting cylinder and will drift or drop its load if pressure is lost or the directional valve is centred. The adjustable air cushion only decelerates the piston at stroke end—it does not lock or hold position. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
