About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-20
The AirTAC SAIJ200X300-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 300 mm stroke that can be fine-tuned down by 20 mm, giving an effective 280-300 mm travel window.
The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic solid-state switches. The robust 40 mm carbon steel rod and M36x2 thread handle significant side loads, while the PT G3/4 tapered port ensures high airflow for the 30-500 mm/s speed range. The rear stopper acts purely as a travel end-deceleration device, not a lock.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-20 Is Used
Heavy Press Tuning
Dial in the exact 280-300 mm travel end-point during heavy-duty metal pressing operations without physically swapping out the entire cylinder.
Product Changeover
Quickly adapt machinery end-stops for new oversized product dimensions on a production line using the 20 mm rear adjustment screw.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-20 the Right Cylinder?
The 20 mm rear adjuster allows you to dial in the exact end-position at commissioning without swapping the cylinder or adding external stops, a major advantage over a fixed-stroke SAI model. Because the nominal 300 mm stroke is substantial, always use an external guide rail to support the load and prevent rod bending.
To replace an ISO 15552 cylinder, match the 200 mm bore, 300 mm stroke, 20 mm adjustment, PT G3/4 port, and the required mounting accessory from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster and air cushions only decelerate the load; they do not hold it without live air. For true fail-safe load holding, select the SAIL or BSAI series instead.
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 SAIJ200X300-20 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 300 mm down to 280 mm. This creates a 280-300 mm usable window for fine-tuning the retract end-position at commissioning without changing the cylinder.
