About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100S
The AirTAC SAIJ32X270-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 170 to 270 mm, allowing you to dial back the nominal 270 mm stroke by up to 100 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod for superior corrosion resistance and carries an -S magnet for position sensing.
This model features a PT tapered port thread and operates at speeds between 30 and 800 mm/s. The rear adjuster functions strictly as a mechanical stop to set the end position, meaning it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100S Is Used
Machine Commissioning
Fine-tune the 170 to 270 mm travel window during initial setup to perfectly dial in the end-of-stroke position without machining external stopper blocks.
Product Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when switching between different product sizes, minimizing downtime between runs.
Variable End Stops
Use the 100 mm rear adjustment range to accommodate varying material lengths or positions on an assembly line without replacing the actuator.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires precise end-position tuning without swapping components or adding external stops. If you need greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if your force requirements are lower, you can step down to a smaller profile. Because the stroke is 270 mm, an external guide is recommended to prevent excessive side loading on the piston rod.
To match this ISO 15552 interchangeable cylinder, specify the 32 mm bore, 270 mm stroke, 100 mm adjustment range, PT port thread, and the -S magnet option for CMSE reed or DMSE electronic sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX270-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100 mm. This gives you a usable travel window of 170 to 270 mm. The adjuster only sets the end position; it does not lock or hold the load without live air pressure.
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. Because it includes the -S magnet option, it is fully compatible with AirTAC CMSE reed switches and DMSE electronic solid-state sensors.
