About the Airtac SC80 Standard Cylinder SC80X50SH
The SC80X50SH is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a compact 50 mm stroke. At 0.5 MPa it generates 2513 N of push force, making it a strong performer for short-throw clamping and pressing tasks. The built-in magnet (-S) allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model is equipped with Viton (FKM) seals (-H suffix), shifting the operating temperature range to 0–150 °C for hot-environment duty. The 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration. Total extended body length is approximately 232 mm (A=182 mm + 50 mm stroke), fitting into tight machine envelopes.

Where the Airtac SC80 Standard Cylinder SC80X50SH Is Used
Hot Press & Molding
Viton seals withstand 150 °C ambient, making this cylinder ideal for short-stroke clamping in heated platen presses, thermoforming tools, and rubber molding machines.
Sensor-Controlled Ejectors
The built-in magnet enables CMSG/DMSG sensors to confirm full extension and retraction in automated part-ejection stations, ensuring cycle integrity.
High-Temperature Workholding
Delivers 4523 N at 0.9 MPa for fixturing in ovens or soldering lines. The short 50 mm stroke provides rigid, fast-acting clamping with minimal rod deflection.
Is the Airtac SC80 Standard Cylinder SC80X50SH 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 body is critical, the 63 mm bore SC63 delivers 1559 N at the same pressure. When replacing an existing cylinder, match five points exactly: 80 mm bore, 50 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 tie-rod unit.
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 SC80X50SH FAQ
At 0.7 MPa operating pressure, the 80 mm bore generates 3518 N of push force. The pull force on the retract stroke is 2268 N at 0.5 MPa (confirm retract force at 0.7 MPa from the full datasheet curve).
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=182 mm). It is not dimensionally interchangeable with ISO 15552 mounts. Replace only with another AirTAC SC80 tie-rod cylinder matching the bore, stroke, PT ports, magnet option, and Viton seal.
