About the Airtac SC100 Standard Cylinder SC100X305
The AirTAC SC100X305 is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 305 mm stroke, it provides a substantial force class for medium-to-heavy industrial linear motion, driven by a 25 mm diameter piston rod.
This tie-rod cylinder features a body length A of 188 mm, giving a total extended length of approximately 493 mm. The adjustable air cushion (29 mm length) decelerates the piston smoothly at stroke ends. Standard PT1/2 ports supply filtered air, and the TPU seals operate reliably from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X305 Is Used
Pallet Stop & Lift
The 3927 N push force at 0.5 MPa handles heavy pallet stopping and lifting stations on conveyor lines, providing a robust 305 mm stroke for vertical or horizontal actuation.
Press & Clamping
Ideal for pneumatic presses and heavy-duty clamping fixtures, the SC100X305 exerts up to 7068 N at 0.9 MPa to hold workpieces securely during machining or assembly.
Bin & Hopper Gate
Operates large slide gates on bins or hoppers handling bulk materials. The 100 mm bore provides the force to shift heavy gates, while the 305 mm stroke offers a wide opening.
Is the Airtac SC100 Standard Cylinder SC100X305 the Right Cylinder?
For higher force, step up to the SC125 bore (6136 N push at 0.5 MPa). If 3927 N is more than needed, the SC80 bore provides 2513 N at 0.5 MPa. This 305 mm stroke places moderate bending loads on the 25 mm rod; for applications with significant side forces, use an external guide rail or a guided cylinder to protect the rod bearing and seals.
To ensure a correct replacement, match five points: 100 mm bore, 305 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and no magnet. This model is a standard SC tie-rod cylinder, not an ISO 15552 profile, and is dimensionally shorter.
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 SC100X305 FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X305 is a double-acting cylinder and will not hold position if pressure is exhausted or the valve is centered. The piston will drift or drop. For load holding without live pressure, add a pilot-operated check valve or an external mechanical rod lock.
