About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-30S
The AirTAC SAIJ32X200-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal stroke by up to 30 mm. This creates a precise 170-200 mm usable travel window for fine end-position tuning during commissioning without swapping out the barrel. It delivers 402 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for improved corrosion resistance.
This model includes a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear adjuster acts purely as a mechanical stop to set the retract position and decelerate the load, but it does not hold the load without live air pressure. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-30S Is Used
Machine Changeover
Dial in the 170-200 mm travel window during product size changes without replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to hit exact machine coordinates using the rear adjusting screw.
Light Assembly Lines
Provides 402 N of push force at 0.5 MPa for light-duty assembly tasks requiring precise variable end-stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-30S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires exact end-stop tuning on a 200 mm stroke, stepping up from smaller units or down from a 40 mm bore that provides 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers where the end position shifts slightly, eliminating the need to bolt on external stops or buy a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 32 mm bore, 200 mm stroke, 30 mm adjustment, PT tapered ports, and the -S magnet.
Because the nominal stroke is 200 mm, the 12 mm rod and M10x1.25 thread provide sufficient rigidity, but always guide the load externally to prevent side-load damage. For load-holding without live pressure, select a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
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 SAIJ32AX200-30S 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. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 30 mm, creating a usable travel window of 170-200 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
