About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-40
The AirTAC SAIJ32X270-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 270 mm stroke that can be fine-tuned down by up to 40 mm, yielding a usable travel window of 230 to 270 mm. This allows exact end-position calibration during commissioning without swapping hardware. The 32 mm bore generates 402 N of push force at 0.5 MPa and uses a G1/8 port.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not enabled out of the box. The rear adjuster acts purely as a travel stop for deceleration and does not lock the load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-40 Is Used
Machine Changeover
Dial in the 230-270 mm travel window during product size changes to set new end positions rapidly without mechanical rebuilds.
End-Position Tuning
Trim the stroke by up to 40 mm at commissioning to perfect the exact resting point of the tooling, avoiding costly machining errors.
Variable End Stops
Ideal for diverter gates or push-off mechanisms where the rear stopper must be tweaked to accommodate varying package lengths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-40 the Right Cylinder?
Select this 32 mm bore model when an application demands precise variable end-stops; if higher thrust is required, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. An adjustable stroke is chosen over a fixed SAI cylinder when machine setups require frequent product changeovers or fine-tuning without adding external stops. To match this exact configuration for an ISO 15552 replacement, specify the 32 mm bore, 270 mm stroke, 40 mm adjustment, PT port thread, SUS304 (B) rod material, and no magnet.
Because the 270 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread still require external guiding to prevent excessive side-loading. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, consider an external rod lock or pilot-operated check valve.
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 SAIJ32BX270-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 270 mm down to 230 mm. This provides a 230-270 mm adjustable window for fine-tuning the retract end position without changing the cylinder.
