About the Airtac SAI50 Standard Cylinder SAI50AX270
The AirTAC SAI50X270 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 270mm stroke. It delivers a robust 982 N of push force at 0.5 MPa, making it well-suited for medium-duty handling and positioning tasks.
This unit is configured with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and surface durability. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of switches, though a magnet is not installed in this specific configuration.

Where the Airtac SAI50 Standard Cylinder SAI50AX270 Is Used
Material Diverting
Actuates diverter arms on packaging lines to route products into different lanes based on sensor inputs.
Vertical Lifting
Raises and lowers lighter pallets or tote bins in automated storage and retrieval systems.
Clamp Positioning
Moves workholding clamps into position over medium-sized jigs prior to machining operations.
Is the Airtac SAI50 Standard Cylinder SAI50AX270 the Right Cylinder?
Providing 982 N of thrust at 0.5 MPa, this 50mm bore is a solid step up from the 40mm bore (628 N) for heavier payloads, without jumping to the larger 63mm bore (1559 N). For this 270mm stroke, be mindful of side loads; long unsupported rods are prone to bending under lateral stress, so utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature wear.
This model uses a PT tapered G1/4 port and supports standard ISO 15552 mounting accessories like FA/FB flanges or TC trunnions. Because it lacks a magnet, position sensing requires external switches or a mechanical stop. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; they do not hold a load. If your application requires fail-safe position holding without air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
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 SAI50 Standard Cylinder SAI50AX270 FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. If operating pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes, the SAI50X270 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting footprint and G1/4 port size, allowing it to serve as a direct replacement for other ISO 15552 profile cylinders.
