About the Airtac SAI100 Standard Air Cylinder SAI100X120S
The AirTAC SAI100X120-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 120mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty actuation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern machinery.
This specific configuration includes a magnetic piston (-S) for non-contact position detection using CMSE or DMSE series switches housed within the dual sensor grooves on the barrel. The standard carbon steel piston rod offers durable performance, while the PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X120S Is Used
Heavy-Duty Stamping
Provides the substantial force needed for metal forming, punching, and press operations in automated fabrication lines.
Pallet Diversion
Actuates heavy diverters and gates on conveyor systems to route large pallets or bulky goods reliably.
Industrial Clamping
Secures large workpieces during CNC machining or heavy welding processes, ensuring rigid and safe holding.
Is the Airtac SAI100 Standard Air Cylinder SAI100X120S the Right Cylinder?
Selecting this 100mm bore cylinder is ideal when an application requires significantly more force than a 80mm bore can provide (2513 N at 0.5 MPa), but without stepping up to a larger 125mm unit. Its 120mm stroke offers balanced extension for medium-travel workholding and lifting. Because it is a double-acting cylinder, it relies on continuous air pressure to maintain its position; if air is lost, the load will drift.
As a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders, serving as a drop-in replacement. When ordering, specify the 100mm bore, 120mm stroke, PT port threads, and the -S magnet option for sensor compatibility.
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.
