About the Airtac SC80 Standard Cylinder SC80X300SH
The SC80X300SH is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 300 mm stroke, combined with a 25 mm diameter piston rod and 28 mm adjustable air cushion, makes it a robust mid-range actuator for industrial automation.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade.

Where the Airtac SC80 Standard Cylinder SC80X300SH Is Used
High-Temperature Material Handling
The Viton seals allow this cylinder to operate reliably in ovens, autoclaves, or near heat-sealing machinery where ambient temperatures reach up to 150°C, pushing or diverting hot products on a conveyor line.
Sensor-Controlled Clamping
The built-in magnet works with CMSG sensors to confirm clamp engagement in CNC fixtures or welding jigs. The 300 mm stroke provides ample reach for loading and unloading large workpieces.
Hot Press Actuation
Delivering 4523 N at 0.9 MPa, this cylinder can apply substantial pressing force in heated platen applications. The FKM seals maintain integrity under sustained thermal load, ensuring consistent cycle times.
Is the Airtac SC80 Standard Cylinder SC80X300SH the Right Cylinder?
Choose the SC80 for applications needing around 2500 N of force at standard plant pressure; if your load requires more, step up to the SC100 which provides 3927 N at the same 0.5 MPa. For strokes of 300 mm and above, be mindful of side loading—an unsupported 25 mm rod can bend under off-axis forces. Use an external linear guide or switch to a guided cylinder if side loads are present.
When replacing an existing cylinder, match five key points: 80 mm bore, 300 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile unit, so dimensional interchangeability is limited to other AirTAC SC series cylinders of the same configuration.
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 SC80X300SH FAQ
At 0.7 MPa operating pressure, the 80 mm bore generates a theoretical push force of 3518 N. The pull force on the retract stroke is 2268 N at 0.5 MPa, accounting for the 25 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder (body length A is 182 mm for the 80 mm bore). It will only directly interchange with another AirTAC SC80 tie-rod cylinder matching the same stroke, port thread, magnet option, and mounting.
