About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40S
The AirTAC SAIJ32X450-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 410-450 mm usable travel window, allowing you to dial back the 450 mm nominal stroke by up to 40 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it handles lighter loads with precision.
This SKU uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel carries sensor grooves on both sides, and the PT tapered port threads match standard pneumatic fittings.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40S Is Used
Product Changeover
Quickly reposition the retract stop by up to 40 mm when switching between product sizes on a packaging line, avoiding cylinder swaps.
End-Position Tuning
Fine-tune the final end-of-stroke position during machine setup to perfect a delicate pressing operation without external stops.
Variable Diverter Stroke
Adjust the actuation distance of a conveyor routing gate on the fly to accommodate different package widths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-40S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa and variable end-position tuning. If your process needs more power, stepping up to the 40 mm bore yields 628 N. The rear adjuster screw acts solely as a travel stop to fine-tune the 410-450 mm window; it does not hold the load without live air. For true load-holding without pressure, select an SAIL or BSAI cylinder.
Because the 450 mm stroke is relatively long for a 32 mm bore, the M10x1.25 rod is susceptible to side-loading. Always guide the load externally to prevent rod binding. This unit is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX450-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the 450 mm nominal stroke down to 410 mm. It functions purely as a mechanical stop to set the end position and does not lock the load.
