About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40S
The AirTAC SAIJ32X270-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 270 mm nominal travel by up to 40 mm. This creates a precise 230-270 mm usable window for fine-tuning the retract end position during commissioning without adding external stops. It features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
Operating at 0.5 MPa, this 32 mm bore generates 402 N of push force and 345 N of pull force. The extruded aluminum barrel includes sensor grooves on both sides, and the unit supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear adjuster acts strictly as a travel stop, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40S Is Used
End-Position Tuning
Dial in the exact retract position within a 230-270 mm window during commissioning without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop to accommodate different product sizes on a single assembly line.
Machine Setup
Fine-tune the travel limit on automated machinery to prevent overtravel and ensure precise positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product changeover flexibility, rather than a fixed-stroke SAI cylinder. If your application needs less force, stepping down is not an option in this footprint, but if you need more thrust, stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa. Because the stroke is 270 mm, the 12 mm rod and M10x1.25 thread carry moderate side loads, but an external guide is recommended for heavy off-center loads.
To match this ISO 15552 cylinder for replacement, verify the 32 mm bore, 270 mm stroke, 40 mm adjustment range, PT tapered port, and the -S magnet option. For load-holding without live pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is not a brake.
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 Adjustable Cylinder SAIJ32 SAIJ32AX270-40S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm from the 270 mm nominal length, providing a usable travel window of 230-270 mm. It acts as a mechanical stop to set the end position and is not a lock.
At 0.5 MPa operating pressure, the SAIJ32X270-40-S generates 402 N of push force and 345 N of pull force. It can reach a maximum of 82 kgf at 1.0 MPa.
