About the Airtac SC80 Standard Cylinder SC80X28
The AirTAC SC80X28 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum 0.9 MPa operating pressure. Its 80 mm bore and 28 mm stroke make it a compact yet powerful actuator for short, repetitive linear movements, with a 25 mm diameter piston rod providing excellent rigidity for the stroke length.
This model features a 182 mm body length (A dimension) and an adjustable pneumatic cushion of 28 mm at each end to decelerate the piston smoothly. Standard PT3/8 ports and an M20x1.5 rod thread ensure straightforward integration into pneumatic circuits, operating reliably with filtered air between -20 and +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X28 Is Used
Short-Stroke Clamping
The 28 mm stroke provides a fast, rigid clamping action for workpieces on assembly jigs and conveyor stops, where the 2513 N force at 0.5 MPa ensures a secure hold.
Press-Fit Operations
Ideal for light press-fit or stamping tasks requiring a short, powerful advance. The 25 mm rod resists buckling under the 4523 N maximum push force at 0.9 MPa.
Ejector Mechanisms
Delivers a quick, repeatable punch to eject parts from molds or fixtures. The adjustable cushion prevents impact damage at the end of the short, high-speed stroke.
Is the Airtac SC80 Standard Cylinder SC80X28 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 overall length is required, the 63 mm bore SC63 series offers 1559 N at the same pressure. This 28 mm stroke is well within the standard range for the 80 mm bore, ensuring fast availability.
When replacing an existing cylinder, match five key points: 80 mm bore, 28 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC80 is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders; it must replace another AirTAC SC80 or an equivalent tie-rod cylinder.
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 SC80X28 FAQ
The push force is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and reaches a maximum of 4523 N at the 0.9 MPa operating pressure limit. The theoretical force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. For a direct replacement, you must use another AirTAC SC80 tie-rod cylinder with a 28 mm stroke and matching PT3/8 ports.
