About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-30
The AirTAC SAIJ32X40-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 10 to 40 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered ports.
The rear adjustment screw lets you fine-tune the retract end position at commissioning without adding external stops. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 10-40 mm window during machine setup without swapping cylinders.
Product Changeover
Quickly adapt end-stops on a packaging line when handling different product sizes or varying material lengths.
Precision Assembly
Use the fine adjustment capability to set precise pressing or positioning depths for delicate 32 mm bore operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-30 the Right Cylinder?
Choose this 32 mm bore when 402 N push force at 0.5 MPa is sufficient, or step up to the 40 mm bore for 628 N if your load requires more thrust. The adjustable stroke is ideal for product changeovers where the end-stop varies, unlike a fixed SAI cylinder. For strokes under 300 mm, side-load is minimal, but always guide external loads. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, select an SAIL or BSAI cylinder. ISO 15552 replacement requires a 32 mm bore, 40 mm stroke, 30 mm adjustment, PT port, and standard mounting.
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 SAIJ32BX40-30 FAQ
It features a rear stopper screw that allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 10 to 40 mm for precise end-position tuning.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
