About the Airtac SC100 Standard Cylinder SC100X355
The AirTAC SC100X355 is a double-acting single-rod pneumatic cylinder delivering 3927 N push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 355 mm stroke, this model uses a 25 mm diameter piston rod and PT1/2 ports, making it well-suited for medium-duty clamping, pressing, and material-handling tasks that require a robust force output.
This tie-rod cylinder features an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 543 mm. Operating on filtered air (40 µm) from 0.15 to 1.0 MPa, the standard TPU/NBR seals provide a working temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X355 Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa reliably stops and transfers heavy pallets on conveyor lines, with the 355 mm stroke providing ample reach across wide roller beds.
Heavy-Duty Clamping
Ideal for welding jigs and assembly fixtures, this cylinder applies up to 7068 N of clamping force at 0.9 MPa to secure large workpieces during machining or fabrication.
Press & Forming Assist
Delivers consistent, controlled force for small pneumatic presses, riveting stations, or forming dies, with the adjustable air cushion protecting tooling from shock at the end of each cycle.
Is the Airtac SC100 Standard Cylinder SC100X355 the Right Cylinder?
The SC100X355 occupies a force class of roughly 4000 N at 0.5 MPa. If your application requires a lighter, more compact actuator, stepping down to the 80 mm bore (SC80 series) reduces push force to 2513 N at the same pressure. For significantly higher force, the 125 mm bore (SC125 series) delivers 6136 N at 0.5 MPa. Always match the bore, 355 mm stroke, PT1/2 port thread, and basic mounting when replacing an existing unit.
At a 355 mm stroke, the 25 mm rod is relatively long. If the load applies any side force, the rod bearing can experience high bending stress. In such cases, use an external linear guide or a guided cylinder to absorb the side load and prevent premature seal wear or rod buckling. For position sensing, this model can be ordered with a built-in magnet (add suffix -S) to accept CMSG/DMSG sensors.
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 SC100 Standard Cylinder SC100X355 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X355 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load or position without live pressure, you must add a mechanical lock, an external rod brake, or a pilot-operated check valve in the circuit.
