About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-100
The AirTAC SAIJ200X290-100 is a double-acting ISO 15552 profile cylinder featuring a robust 200 mm bore and a 290 mm stroke. Equipped with a rear mechanical stopper, it provides a usable travel window of 190-290 mm, allowing you to dial back the stroke by up to 100 mm during commissioning without swapping the unit. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it ideal for heavy-duty positioning.
This extruded aluminum barrel design incorporates sensor grooves on both sides for flexible switch mounting. The carbon steel piston rod features an M36x2 thread and a 40 mm diameter, providing excellent rigidity to withstand high side loads, though an external guide is still recommended for unsupported loads. Pneumatic connections use a PT G3/4 tapered port, and the variable air cushions at both ends absorb heavy impact energies at the travel extremes.

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 SAIJ200X290-100 Is Used
Heavy Press Positioning
Fine-tune the 190-290 mm travel window during setup to precisely crush or form heavy materials without recalibrating the entire press line.
Large Product Diversion
Adjust the end stop on the fly to handle varying pallet sizes on a conveyor, accommodating up to 100 mm of product length differences seamlessly.
Automated Assembly Stops
Dial in the exact retraction point for heavy automotive subassemblies during commissioning, ensuring perfect alignment before final joining.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-100 the Right Cylinder?
The 100 mm adjustment range is highly valuable for product changeovers on large machinery, allowing you to reposition the end stop on the fly rather than machining new spacers or installing a fixed-stroke SAI cylinder. For any heavy loads moved over this 290 mm stroke, adding an external linear guide is essential to prevent rod damage and premature seal wear.
When matching this for an ISO 15552 replacement, verify the 200 mm bore, 290 mm stroke, PT G3/4 port thread, and the 100 mm adjustment code. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, intentionally omitting FB, CA, CB, and CR brackets. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure; for true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series, or use an external pilot-operated check valve.
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 SAIJ200X290-100 FAQ
The rear adjuster acts as a mechanical stopper that trims the effective travel back from the nominal 290 mm. You can set the stroke anywhere in a 190-290 mm window, which is ideal for fine-tuning end positions at commissioning without external stops.
