About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-40S
The AirTAC SAIJ32X350-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 310 to 350 mm, allowing you to dial back the 350 mm nominal stroke by up to 40 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing using AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop, meaning the cylinder will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-40S Is Used
Stroke Commissioning
Fine-tune the end-of-stroke position within the 310-350 mm window during machine setup without adding external physical stops.
Product Changeover
Quickly adjust the cylinder's retract position to accommodate varying package sizes on a packaging line.
Sensor Positioning
Utilize the integrated magnet with DMSE electronic sensors to confirm the adjusted end position for precise control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-40S the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient, stepping down from a 40 mm bore that yields 628 N. The adjustable 310-350 mm stroke is ideal for variable end-stops or product changeovers, preventing the need to swap a fixed-stroke SAI cylinder. For strokes of 350 mm, the 12 mm rod and M10x1.25 thread carry moderate side loads, but an external guide is recommended for heavy unsupported loads.
To replace an ISO 15552 cylinder, match the 32 mm bore, 350 mm stroke, 40 mm adjustment, PT tapered port thread, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the rear adjuster is a stop and not a lock, use an external rod lock or a SAIL cylinder if you need fail-safe load holding without live air.
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 SAIJ32BX350-40S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull force, operating at speeds between 30 and 800 mm/s.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from 350 mm down to 310 mm without changing the cylinder.
