About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-50S
The AirTAC SAIJ200X240-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, pushing 21991N and pulling 15080N at 0.7 MPa. By turning the external stopper screw, you can shorten the effective stroke by up to 50 mm, creating a precise 190-240 mm usable travel window for exact end-position tuning without swapping hardware.
This bore size utilizes a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet enables position detection via AirTAC CMSE reed or DMSE electronic solid-state switches. Mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ200X240-50S Is Used
Machine Setup Changeover
Dial in the exact 190-240 mm end-position during product size changeovers without fabricating external mechanical stops.
Variable End-Stop Assembly
Adapt the retract stroke dynamically on the fly for multi-variant assembly lines requiring different retraction depths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-50S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust in the ISO 15552 range, as stepping down to a 160 mm bore drops the 0.7 MPa push force to 14074N. The adjustable stroke is selected over a fixed SAI when you need commissioning fine-tuning or variable end-stops during product changeover. For any stroke of 300 mm or more, long unsupported loads require an external guide to prevent rod side-loading, though this 240 mm unit sits safely below that threshold.
Remember that the rear adjuster functions strictly as a travel stop, not a lock; it cannot hold a load without live air pressure. For drop-down load holding, integrate an external pilot-operated check valve or select the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 200 mm bore, 240 mm stroke, 50 mm adjustment, PT tapered port, and -S magnet specifications.

- ✓ 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 SAIJ200X240-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 240 mm stroke by up to 50 mm, providing a 190-240 mm usable travel window for fine-tuning at commissioning.
At 1.0 MPa, the maximum push force reaches 28274N.
