About the Airtac SC80 Standard Cylinder SC80X40
The AirTAC SC80X40 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa, ideal for short-stroke clamping, pressing, and ejecting tasks. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration even in rapid cycling applications.
With a compact body length A of 182 mm plus the 40 mm stroke, this cylinder fits into tight machine envelopes where a robust 80 mm bore actuator is needed. The standard PT3/8 port and M20x1.5 rod thread ensure straightforward pneumatic connections and tooling attachment.

Where the Airtac SC80 Standard Cylinder SC80X40 Is Used
Pneumatic Press
Generates over 2500 N at 0.5 MPa for short-stroke pressing, staking, or assembly operations where a compact actuator footprint is critical.
Part Ejection
Rapidly ejects parts from conveyor lines or moulds. The 28 mm adjustable cushion absorbs impact energy at the end of the 40 mm stroke for reliable high-cycle use.
Clamping Fixture
Provides consistent clamping force for CNC machining fixtures or welding jigs. The M20x1.5 rod thread accepts standard clamping elements.
Is the Airtac SC80 Standard Cylinder SC80X40 the Right Cylinder?
For applications needing more force, step up to the SC100 bore which provides 3927 N at 0.5 MPa. If the 80 mm bore is sufficient but a longer stroke is required, the SC80 family extends to a maximum standard stroke of 1500 mm.
When replacing an existing cylinder, match five points: 80 mm bore, 40 mm stroke, PT port thread, basic mounting (no bracket), and confirm the magnet option (-S) is not required. This model uses the standard TPU seal for -20 to +70 C operation.
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 SC80X40 FAQ
At 0.7 MPa operating pressure, the SC80X40 produces 3518 N of push force. The pull force at the same pressure is 2268 N, accounting for the 25 mm rod diameter.
This standard SC80X40 does not include the built-in magnet. To use CMSG/DMSG/EMSG sensors for position feedback, order the SC80X40-S variant which includes a magnet ring on the piston.
