About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30
The AirTAC SAIJ200X325-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. The integrated rear adjusting screw allows you to shorten the effective travel, providing a usable window of 295 to 325 mm for precise end-position tuning without adding external stops.
This unit uses a SUS420J2 stainless steel rod (material code A) paired with a robust M36x2 rod thread to handle high side loads. It features PT tapered port threads (G3/4) and variable air cushions at both ends. The adjuster acts purely as a travel stop for deceleration and positioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30 Is Used
Heavy Press Tuning
Dial in the exact 295 to 325 mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Rapidly adjust the retract end-stop on automated assembly lines when switching to a new product size, saving setup time and eliminating external stop hardware.
Large Mold Handling
Position heavy molds and tooling with 15708 N of thrust at 0.5 MPa, relying on the M36x2 thread and SUS420J2 rod for durability in industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX325-30 the Right Cylinder?
Choose this 200 mm bore size when you need extreme force (up to 15708 N push at 0.5 MPa) that smaller bores cannot provide. If your application requires less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
Because this cylinder handles a 325 mm stroke, the long unsupported rod is susceptible to bending under lateral stress. An external guide is strongly recommended to prevent side-load damage. This model 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 SAIJ200 Adjustable Cylinder SAIJ200AX325-30 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to trim the nominal 325 mm stroke back by up to 30 mm. This creates a usable travel window of 295 to 325 mm for fine-tuning end positions at commissioning.
