About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-10S
The AirTAC SAIJ200X40-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 30 to 40 mm. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for precise position detection.
This model utilizes a robust 40 mm carbon steel rod with an M36x2 thread, designed to handle substantial side loads, while the 50 mm variable air cushions manage end-of-stroke deceleration. The rear adjustment screw allows you to fine-tune the end position at commissioning without adding external stops, and the PT tapered port threads ensure a tight, reliable pneumatic connection.

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 SAIJ200X40-10S Is Used
Heavy Press Fit Tuning
Dial in the exact 30-40 mm travel during heavy press operations to accommodate material thickness variations without swapping out the entire cylinder.
Product Changeover Stops
Adjust the rear stopper quickly on automated lines when switching product sizes, ensuring precise end-position tuning directly at commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-10S the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires extreme force within a compact 30-40 mm adjustable travel window. The adjustable stroke is ideal for machine setups requiring exact end-position tuning during product changeovers, whereas a fixed-stroke SAI cylinder lacks this commissioning flexibility.
Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead. This SAIJ200X40-10-S is dimensionally interchangeable per ISO 15552, features PT ports, a standard magnet for CMSE / DMSE sensors, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ200X40-10S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The nominal 40 mm stroke can be fine-tuned backward by up to 10 mm via a rear adjusting screw, creating a usable travel window of 30 to 40 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
