About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-30S
The AirTAC SAIJ32X220-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 190 to 220 mm, allowing you to dial back the nominal 220 mm stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for position sensing.
This model features a SUS304 stainless steel rod for corrosion resistance and uses a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to set the end position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-30S Is Used
Variable End-Stop Tuning
Fine-tune the retract position within the 190-220 mm window during machine commissioning to perfectly align packaging folds without swapping hardware.
Product Changeover
Quickly adapt the stroke length on a conveyor sorting gate when handling different package sizes by dialing the rear screw up to 30 mm.
Light-Duty Positioning
Leverage the 402 N thrust and SUS304 rod for precise, corrosion-resistant component placement in small assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-30S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires a 190-220 mm stroke window and precise end-position tuning without adding external stops. It provides 402 N of thrust at 0.5 MPa; if your payload requires more force, step up to the 40 mm bore, which offers 628 N. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for any stroke over 300 mm, an external guide is recommended to prevent rod deflection.
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers. This SAIJ32X220-30-S configuration includes a PT port, SUS304 rod, and a magnet for CMSE or DMSE sensors. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. It is dimensionally interchangeable with ISO 15552 cylinders.

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 SAIJ32BX220-30S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the effective travel from the 220 mm nominal stroke down to 190 mm. This mechanical stop fine-tunes the end position but does not lock the load without continuous air pressure.
