About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-40S
The AirTAC SAIJ32X220-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5MPa, utilizing a 12mm piston rod with an M10x1.25 thread. The integrated rear stopper allows you to trim the nominal 220mm stroke back by up to 40mm, providing a precise 180 to 220mm usable travel window for exact end-position tuning.
This SKU includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for position sensing. It pairs seamlessly with AirTAC CMSE reed and DMSE solid-state switches via the dual-side sensor grooves on the extruded aluminum barrel. The adjuster acts purely as a mechanical stop to fine-tune the retract position without needing external stops, but it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-40S Is Used
Machine Changeover
Dial the stroke back by up to 40mm to adapt the retract end-position for different product sizes without swapping out the entire cylinder.
Commissioning Setup
Fine-tune the 180-220mm travel window during initial machine setup to absorb mechanical tolerances and achieve precise positioning.
Corrosive Environments
Leverage the SUS304 stainless steel rod and adjustable stroke for precise actuation tasks in packaging or food processing lines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-40S the Right Cylinder?
Choose this 32mm bore when your application requires 402N of thrust at 0.5MPa but demands on-the-fly end-position adjustments during commissioning or product changeovers. If you need to step up to the next bore size, the 40mm SAIJ provides 628N of push force at 0.5MPa. The rear adjuster screw lets you dial in the travel window from 180 to 220mm, preventing the need to swap cylinders for minor length differences.
For load-holding without continuous air supply, remember that this cylinder's rear stopper and air cushions function only as travel deceleration, not as a lock; you should look at the SAIL or BSAI series instead. To match this exact ISO 15552 replacement, specify a 32mm bore, 220mm stroke, 40mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting options include 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 SAIJ32BX220-40S FAQ
At 0.5MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It operates at speeds between 30 and 800mm/s and features a 27mm cushion length at both ends.
The rear adjuster screw mechanically stops the piston, allowing you to shorten the 220mm nominal stroke by up to 40mm. This creates a 180 to 220mm usable travel window for fine-tuning without adding external stops.
