About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-20S
The AirTAC SAIJ200X300-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 280-300 mm usable travel window, letting you dial back the 300 mm nominal stroke by up to 20 mm during commissioning without adding external stops.
This 200 mm bore unit uses a robust 40 mm carbon steel piston rod and a PT G3/4 port. It includes variable air cushions at both ends and a magnet for CMSE or DMSE sensors. The rear adjuster acts purely as a travel stop for end-position tuning, not a load lock, so live air is required to hold position.

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 SAIJ200X300-20S Is Used
Heavy Press Setup
Fine-tune the 280-300 mm travel window during machine commissioning to set exact pressing distances without swapping cylinders.
Product Changeover
Quickly adjust the retract end-stop on a packaging line to handle different carton sizes using the 20 mm rear adjuster.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-20S the Right Cylinder?
Choose the adjustable-stroke SAIJ over a fixed SAI when you need fine end-position tuning during product changeovers. For an ISO 15552 replacement match, specify the 200 mm bore, 300 mm stroke, 20 mm adjustment, PT G3/4 port, and the -S magnet.
Because the 300 mm stroke is long, the 40 mm rod and M36x2 thread still need an external guide to manage side loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If you need true load-holding without live air, use an external rod lock or look at the SAIL or BSAI series.
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 SAIJ200X300-20S FAQ
At the maximum operating pressure of 1.0 MPa, the push force reaches 21991 N.
The rear adjuster allows you to shorten the 300 mm nominal stroke by up to 20 mm, giving a usable travel window of 280-300 mm. The adjuster is a travel stop, not a lock, so the cylinder requires live air to hold position.
