About the Airtac SAI100 Standard Air Cylinder SAI100BX350S
The AirTAC SAI100X350-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100mm bore unit is built to handle substantial loads across its 350mm stroke. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches housed in the dual-side grooves of the barrel. Porting is PT tapered thread, and adjustable air cushions at both ends ensure smooth deceleration of large moving masses.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX350S Is Used
Automotive Body Welding
Provides the high clamping thrust needed to hold heavy steel panels firmly in place during robotic spot-welding operations.
Pallet Diverters
Actuates heavy-duty routing gates to redirect loaded pallets along high-throughput material handling conveyor lines.
Press Ejection
Delivers reliable force to eject finished parts from large molding and stamping presses at the end of the machine cycle.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX350S the Right Cylinder?
When sizing this actuator, consider stepping down to the 80mm bore if your application only requires 2513 N of push force at 0.5 MPa, as the smaller cylinder saves valuable space and air consumption. Conversely, if your load demands higher thrust, the 125mm bore provides 6133 N. For this 350mm stroke, the unsupported length of the rod is significant; side loads can cause severe rod-bearing bending and premature wear. Implement an external guide rail or use a dedicated guided cylinder to absorb lateral forces and protect the actuator.
As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other standard profile cylinders of the same bore and stroke. To build a complete system, pair it with a PT port, FA or FB flange mounts, and CMSE sensors. Note that the standard double-acting design relies on continuous air pressure to maintain position; if pneumatic supply is lost, the piston will drift. For applications requiring static load holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
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 SAI100 Standard Air Cylinder SAI100BX350S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X350-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and stroke length are fully interchangeable with other ISO 15552 standard cylinders of the same size, allowing for seamless drop-in replacements.
