About the Airtac SC80 Standard Cylinder SC80X56
The SC80X56 is a double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa (up to 4523 N at 0.9 MPa). With an 80 mm bore and a compact 56 mm stroke, this model is built for short, repetitive linear moves where consistent force is required. The 25 mm diameter piston rod and PT3/8 ports provide robust air flow for rapid cycling.
This cylinder includes an adjustable pneumatic cushion (28 mm length) at both ends, allowing you to dial in smooth deceleration for high-speed applications. The body length A is 182 mm, giving a total extended length of approximately 238 mm. It operates on filtered air from -20 to +70 °C with standard TPU seals, making it a reliable workhorse for general industrial automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X56 Is Used
Part Stops & Gates
The 56 mm stroke and 2513 N force at 0.5 MPa make the SC80X56 ideal for actuating sturdy part stops or diverting gates on conveyor lines handling medium-weight packages.
Light Press-Fit Assembly
With up to 4523 N of force at 0.9 MPa, this cylinder can reliably seat bearings, bushings, or pins in light press-fit operations where a short, controlled stroke is needed.
Clamping & Fixturing
The robust 25 mm rod and tie-rod construction handle the side loads common in welding or machining fixtures, providing repeatable clamping force for workpieces during processing.
Is the Airtac SC80 Standard Cylinder SC80X56 the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N of push force at the same 0.5 MPa pressure. If a shorter, lighter unit is preferred, the SC63 bore offers 1559 N. When replacing this cylinder, match five points: 80 mm bore, 56 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC is a tie-rod design 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 SC80X56 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
This specific model code (SC80X56) does not include the -S magnet option, so the piston does not have a built-in magnet. To use CMSG or DMSG sensors, you would need the SC80X56-S variant. Without the magnet, external limit switches must be used for position sensing.
