About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20
The AirTAC SAIJ200X600-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 580-600mm usable travel window, letting you dial back the nominal 600mm stroke by up to 20mm during commissioning. This bore generates 15708N of push force and 15080N of pull force at 0.5MPa, making it suited for moving heavy loads.
This unit uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel. It features PT tapered ports sized at G3/4. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is not equipped with a piston magnet for internal sensors.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20 Is Used
Heavy Press Tuning
Fine-tune the 580-600mm stroke end-position on heavy presses to accommodate material thickness variations without replacing the cylinder.
Large Conveyor Diverter
Adjust the retract stopper during product changeovers to set exact diverting positions for varying pallet sizes on a high-capacity line.
Automated Assembly Setup
Dial in the exact end-of-stroke contact point during machine commissioning to prevent overtravel damage to large assembly tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20 the Right Cylinder?
Choose this 200mm bore when 160mm falls short, as the 160 bore yields 10053N of push force at 0.5MPa compared to this model's 15708N. The adjustable rear stopper is selected over a fixed SAI cylinder when you need precise end-position tuning without adding external stops or swapping the barrel. Speeds range from 30-500mm/s.
Because the stroke is 600mm, the 40mm diameter rod can experience leverage forces; an external guide is recommended to prevent side-loading damage. The rear adjuster acts only as a travel stop, not a load-holding lock. For true position holding without live air, select an AirTAC SAIL or BSAI model. This cylinder is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200AX600-20 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it delivers a maximum push force of 3204 kgf.
The rear adjuster screw lets you shorten the 600mm nominal stroke by up to 20mm, creating a 580-600mm usable travel window. This allows precise end-position tuning at commissioning without external stops.
