About the Airtac SC80 Standard Cylinder SC80X703
The AirTAC SC80X703 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa max operating pressure). Its 703 mm stroke suits long-reach material transfer and positioning tasks where a compact ISO 6430-class footprint is not required.
This model features a 25 mm piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the load smoothly. The tie-rod construction keeps the body length A to just 182 mm, making the extended assembly approximately 885 mm long. The standard TPU seals provide a reliable operating range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X703 Is Used
Long-Stroke Part Transfer
The 703 mm stroke moves components between distant conveyor stations or assembly nests with a push force of 2513 N at standard shop air.
Platen & Press Actuation
Delivers up to 4523 N at 0.9 MPa for pressing, clamping, or holding platens in laminating and light forming operations.
Bin Pushing & Sorting
Extends a 25 mm rod deep into racking or chutes to divert totes and packages, with adjustable cushioning to protect the load.
Is the Airtac SC80 Standard Cylinder SC80X703 the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore provides 3927 N at 0.5 MPa. If a shorter, more rigid assembly is acceptable, the 63 mm bore offers 1559 N at the same pressure. With a 703 mm stroke, side-load management is critical—always guide the rod externally or use a guided cylinder to prevent rod bending and premature bearing wear.
When replacing an existing unit, match five points: 80 mm bore, 703 mm stroke, PT3/8 port thread, basic mounting (no bracket), and the absence of a magnet. The SC series 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 SC80X703 FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
A 703 mm stroke with a 25 mm rod is susceptible to bending under side loads. For long-stroke applications, always use an external guide rail or a guided cylinder to protect the rod bearing and ensure linear motion.
