About the Airtac SC100 Standard Cylinder SC100X44
The SC100X44 is a non-standard stroke variant in the AirTAC SC tie-rod cylinder family, pairing a 100 mm bore with a compact 44 mm stroke. It generates a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), making it a high-force solution for short, powerful linear moves.
Built on a 188 mm body length A, this double-acting cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-stroke, protecting tooling in high-cycle applications.

Where the Airtac SC100 Standard Cylinder SC100X44 Is Used
Short-Stroke Clamping
The 44 mm stroke with 3927 N force at 0.5 MPa is ideal for pneumatic toggle clamps, press fixtures, and assembly jigs where a compact, high-force linear squeeze is needed.
Die Cushion & Ejection
Delivers a powerful, controlled push for ejector pins or short die-cushion strokes in metal forming and plastic injection tooling, leveraging the adjustable cushion for impact reduction.
Product Stop & Divert
Used as a heavy-duty product stop on conveyor lines for pallets or large packages, the 100 mm bore provides the force to halt significant inertial loads in a very short travel distance.
Is the Airtac SC100 Standard Cylinder SC100X44 the Right Cylinder?
Choose the SC100X44 when you need a 100 mm bore's force density in a stroke shorter than the standard 50 mm minimum. If your force requirement is lower, stepping down to an SC80 bore saves space and air consumption (2513 N at 0.5 MPa). For longer strokes up to 1500 mm, the standard SC100 series is available.
To replace an existing cylinder, match five points exactly: 100 mm bore, 44 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and no magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 models.
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 SC100X44 FAQ
At 0.7 MPa operating pressure, the SC100X44 double-acting cylinder produces 5497 N of push force. The pull force on the retract stroke at the same pressure is 3681 N, accounting for the 25 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder of the same bore. The SC100X44 will only drop-in replace another AirTAC SC100 tie-rod cylinder with the same 44 mm stroke, PT ports, and basic mounting configuration.
