About the Airtac SC100 Standard Cylinder SC100X550
The SC100X550 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 3927 N 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 550 mm stroke, this model uses a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 ports, making it a robust actuator for demanding mid-range linear motion tasks.
This cylinder features an adjustable pneumatic cushion at both ends (29 mm cushion length) to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 738 mm. As a standard-stroke model within the 1500 mm maximum for this bore, it is a stock-friendly choice for industrial automation requiring genuine AirTAC reliability.

Where the Airtac SC100 Standard Cylinder SC100X550 Is Used
Heavy Part Clamping
The 3927 N force at 0.5 MPa makes the SC100X550 ideal for building powerful pneumatic clamps and fixtures for welding or machining, securely holding large workpieces during automated processing.
Pallet Stop and Transfer
Deploy this cylinder in conveyor systems as a heavy-duty pallet stop or a 90-degree transfer station pusher, where its 550 mm stroke can move large totes or pallets between lines.
Waste Compaction Gate
Use the SC100X550 to actuate a discharge gate or a compaction plate in recycling and waste management equipment, leveraging its high push force to compress materials against a platen.
Is the Airtac SC100 Standard Cylinder SC100X550 the Right Cylinder?
Select the SC100 bore when your application requires a push force between roughly 3927 N and 7068 N at standard plant air pressures. If your load demands more force, stepping up to the SC125 bore provides 6136 N of push at the same 0.5 MPa. For lighter, more compact needs, the SC80 bore offers 2513 N. Always match the replacement cylinder on all five key points: bore, stroke, PT port thread, basic mounting configuration, and the absence of a magnet.
For this 550 mm stroke, carefully evaluate any side loading on the 25 mm rod. Long, unsupported strokes are susceptible to rod bending and uneven bearing wear if the load is not guided. Using an external guide rail or rod-alignment coupler is strongly recommended to absorb transverse forces and ensure a long service life, rather than relying on the cylinder's rod bearings alone.
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 SC100X550 FAQ
At the standard 0.5 MPa operating pressure, 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 AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so the mounting dimensions and overall length are not interchangeable. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching bore, stroke, PT ports, and basic mounting.
