About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-40
The AirTAC SAIJ200X40-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 40 mm travel back by up to 40 mm, creating a highly flexible 0 to 40 mm usable window. It features a carbon steel rod and a PT tapered G3/4 port.
Because the adjustment mechanism acts as a mechanical stop at the retract end, it decelerates the load without functioning as a lock—live air pressure is still required to hold the load. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, omitting FB, CA, CB, and CR options.

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 SAIJ200X40-40 Is Used
Heavy-Duty Press Tuning
Dial in the exact 0-40 mm travel during press setup to accommodate varying material thicknesses without changing tooling.
Automated Clamp Adjustment
Fine-tune the retract end-stop on a heavy clamping fixture to switch between different product sizes rapidly on the line.
Machine Commissioning
Use the rear adjuster to set the perfect end-position at startup, avoiding the need to machine custom external spacers for the 200 mm bore assembly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-40 the Right Cylinder?
Choose this 200 mm bore when you need immense thrust—stepping down to a 160 mm bore drops your 0.5 MPa push force to 10053 N. The adjustable stroke is ideal for product changeovers or fine-tuning the exact end-stop during machine commissioning without swapping the cylinder or adding external shims. For load-holding without continuous air pressure, this cylinder is not sufficient; you should look at the SAIL or BSAI series, or use an external rod lock.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 40 mm stroke, 40 mm adjustment range, PT G3/4 port, and standard carbon steel rod without a magnet. Although the stroke is short, the 40 mm diameter rod and M36x2 thread handle significant side loads, but an external guide is still recommended for heavy offset loads.

- ✓ 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 SAIJ200X40-40 FAQ
At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 40 mm stroke by up to 40 mm, giving a usable travel window of 0 to 40 mm. It only sets the end-position and does not lock the load without live air pressure.
