About the Airtac SC100 Standard Cylinder SC100X305FA
The AirTAC SC100X305FA is a double-acting tie-rod cylinder with a 100 mm bore and 305 mm stroke, configured with a front rectangular flange (FA mount, part code F-SC100FA) for rigid panel or bulkhead installation. At 0.5 MPa it pushes with 3927 N and pulls with 3681 N, placing it in a force class suitable for heavy pressing, clamping, and lifting tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 rod thread and PT1/2 port threads. The adjustable air cushion (29 mm length) decelerates the 305 mm stroke smoothly, while the TPU seals and standard PT ports keep it ready for filtered-air systems operating at -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X305FA Is Used
Pallet Stop & Lift Gate
The 3927 N push force at 0.5 MPa and front-flange mount make this cylinder ideal for raising or stopping heavy pallets on conveyor lines, where rigid panel mounting absorbs reaction forces directly.
Heavy-Duty Clamping Press
With 7068 N of thrust available at 0.9 MPa, the SC100X305FA suits pneumatic clamping fixtures and assembly presses that require a solid 305 mm stroke to clear the workpiece before applying full force.
Bulkhead-Actuated Ejector
The FA front flange bolts directly to a machine bulkhead, letting the 305 mm stroke push parts, scrap, or finished product out of a die or fixture with repeatable, cushioned end-of-stroke action.
Is the Airtac SC100 Standard Cylinder SC100X305FA the Right Cylinder?
Choose the SC100 when the SC80’s push force of 2513 N at 0.5 MPa is marginal for your load—stepping up to the 100 mm bore adds over 1400 N of push capacity without changing the rod diameter. For strokes of 300 mm and above, watch for side-load bending on the 25 mm rod; if the load is not guided externally, add a linear guide or switch to a guided cylinder to protect the rod bearing and seals.
When replacing an existing cylinder, match five points: 100 mm bore, 305 mm stroke, PT1/2 ports, the FA front-flange mounting accessory (F-SC100FA), and the absence of a magnet. This ensures drop-in fit on the same mounting face and air connections.
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 SC100X305FA FAQ
At the standard 0.5 MPa operating pressure, 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 SC series is a tie-rod cylinder and is shorter in overall body length than an ISO 15552 profile cylinder, so mounting dimensions and tie-rod spacing will not match. Replace only with another AirTAC SC series cylinder matching the 100 mm bore, 305 mm stroke, PT1/2 ports, and FA front flange mount.
