About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75
The AirTAC SAIJ32X200-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 125-200 mm usable travel window by allowing you to dial back the 200 mm nominal stroke by up to 75 mm. Delivering 563 N of push force at 0.7 MPa, it fits compact automation setups requiring exact end-position tuning.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to fine-tune travel, so live air pressure is still required to hold the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75 Is Used
Machine Changeover
Dial in the 125-200 mm travel window during product size transitions without swapping out the physical cylinder assembly.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect pressing or clamping depth without adding bulky external mechanical stops.
Variable Diverter Stops
Adjust the retract distance on the fly to handle different package lengths moving down a conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-75 the Right Cylinder?
Choose this 32 mm bore when a 40 mm bore (879 N push at 0.7 MPa) would be physically oversized or deliver unnecessary thrust for your fixture. The 75 mm adjustment range is ideal for machines that process varying part sizes, letting you reposition the end-stop during changeover rather than physically swapping the cylinder or adding external stops.
For a drop-in ISO 15552 replacement, match the 32 mm bore, 200 mm stroke, 75 mm adjustment, PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Because the total stroke is 200 mm, ensure external guidance is used to prevent excessive side-loading on the 12 mm rod. If you need fail-safe load holding without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ 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 SAIJ32AX200-75 FAQ
The rear adjuster acts as an external mechanical stop, allowing you to shorten the 200 mm nominal stroke by up to 75 mm. This creates a 125-200 mm usable travel window that can be fine-tuned during commissioning.
At 0.7 MPa operating pressure, the SAIJ32X200-75 provides 563 N of push force and 483 N of pull force. It can reach a maximum of 801 N at 1.0 MPa.
