About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-20
The AirTAC SAIJ200X900-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suitable for heavy-duty industrial tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning.
This model provides a 900 mm nominal stroke with a 20 mm rear adjustment range, creating a usable travel window of 880 to 900 mm. This allows you to fine-tune the retract end-position during commissioning without adding external stops. The carbon steel rod features an M36x2 thread, and the cylinder uses PT tapered G3/4 porting. It supports speeds of 30-500 mm/s and includes adjustable air cushions at both ends to manage heavy impact deceleration.

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 SAIJ200X900-20 Is Used
Heavy Press Setup
Fine-tune the 880-900 mm stroke end-stop during press commissioning to accommodate varying material thicknesses without external spacers.
Product Changeover
Dial in the retract position on automated packaging lines when switching between different box sizes, ensuring precise mechanical positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-20 the Right Cylinder?
Selecting this 200 mm bore cylinder provides a maximum push force of 3204 kgf at 1.0 MPa. Choose the SAIJ adjustable-stroke variant over a fixed SAI model when you need precise end-position tuning for machine changeovers or varying product sizes.
Because the stroke is 900 mm, the long unsupported piston rod is susceptible to side loads; an external guide mechanism is recommended to prevent premature wear. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock. For load-holding without live air pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200X900-20 FAQ
At 1.0 MPa, it reaches a maximum push force of 3204 kgf.
The rear adjuster screw lets you shorten the 900 mm nominal stroke by up to 20 mm, providing an effective travel window of 880 to 900 mm. This stopper fine-tunes the end position but does not lock the load without live air.
