About the Airtac SC80 Standard Cylinder SC80X50
The AirTAC SC80X50 is an 80 mm bore double-acting tie-rod cylinder with a compact 50 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable end-of-stroke deceleration for short, high-cycle clamping and positioning tasks.
With a body length A of 182 mm and a total extended length of just 232 mm, this cylinder fits into tight machine envelopes while offering the thrust of a larger bore. The standard PT3/8 ports and TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X50 Is Used
Short-Stroke Clamping
The 50 mm stroke and 2513 N force at 0.5 MPa make this cylinder ideal for pneumatic toggle clamps and workpiece fixturing in machining centers.
Ejection & Stamping
Delivers a fast, powerful punch for ejecting parts from injection molds or operating light stamping dies with its 25 mm rod and adjustable cushion.
Diverter Gates
Quickly actuates diverter gates on conveyor lines. The 80 mm bore provides ample force to move product guides with a short, decisive motion.
Is the Airtac SC80 Standard Cylinder SC80X50 the Right Cylinder?
For applications needing more force in the same 50 mm stroke, the 100 mm bore SC100X50 steps up to 3927 N push at 0.5 MPa. If space is a constraint, the 63 mm bore SC63X50 provides 1559 N. Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option. This basic model has no magnet or mounting bracket.
At 50 mm stroke, side-load bending is minimal, but ensure the rod is aligned axially with the load. For guided linear motion, pair this cylinder with an external guide rail rather than relying on the rod bearing alone.
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 SC80X50 FAQ
At 0.7 MPa operating pressure, the SC80X50 produces a push force of 3518 N. The maximum push force at 0.9 MPa is 4523 N, and the theoretical force at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. Use it to replace another AirTAC SC80 tie-rod cylinder with matching bore, stroke, PT ports, and mounting.
