About the Airtac SC40 Standard Cylinder SC40X205S
The AirTAC SC40X205 is a double-acting pneumatic cylinder with a 40 mm bore and 205 mm stroke, delivering a push force of 628 N at 0.5 MPa (up to 1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This tie-rod cylinder has a compact body length of 142 mm, making it shorter than an equivalent ISO 15552 profile. With PT1/4 ports and standard TPU seals rated for -20 to +70 °C, it suits general industrial automation where a genuine AirTAC actuator is specified.

Where the Airtac SC40 Standard Cylinder SC40X205S Is Used
Small Part Ejection
The 628 N push force at 0.5 MPa is ideal for ejecting lightweight components from conveyors or indexing stations, with the 205 mm stroke providing ample reach across a standard belt width.
Clamping & Fixturing
Provides consistent, controlled clamping pressure for woodworking or light metalworking jigs. The adjustable cushion reduces impact noise and vibration at the end of the 205 mm stroke.
Diverting Gates
Operates diverter flaps on packaging lines or chutes. The double-acting function ensures positive retraction, and the tie-rod design allows easy maintenance in dusty environments.
Is the Airtac SC40 Standard Cylinder SC40X205S the Right Cylinder?
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If a shorter stroke and lower force are acceptable, the 32 mm bore SC32 series offers 402 N. Always match replacement cylinders on all five key points: 40 mm bore, 205 mm stroke, PT1/4 port thread, basic (no) mounting accessory, and no built-in magnet. At this 205 mm stroke, side loads should be avoided; if the rod must bear a lateral force, use an external linear guide or a guided cylinder to prevent rod bending and premature seal wear.
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 SC40 Standard Cylinder SC40X205S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length (142 mm + stroke) than a standard ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC40 cylinder of the same stroke, port thread, and mounting configuration.
