About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-10
The AirTAC SAIJ200X650-10 is a double-acting ISO 15552 profile cylinder engineered to deliver massive thrust, pushing 15708 N at 0.5 MPa. It features a 650 mm nominal stroke equipped with a rear mechanical stopper that allows you to trim the effective travel back by up to 10 mm, creating a precise 640-650 mm usable window for final commissioning tweaks.
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, though this configuration ships without a magnet, meaning position sensing via CMSE or DMSE switches is not supported without adding the -S option.

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 SAIJ200X650-10 Is Used
Heavy Press Tuning
Dial in the exact bottom dead center of a high-tonnage press within the 640-650 mm window, ensuring perfect crimping depth without machining new spacers.
Large Mold Changeover
Adapt the end-stop quickly when swapping heavy molds on a production line, using the 10 mm rear adjuster to accommodate slight variances in tooling height.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-10 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force, as it generates up to 3204 kgf at 1.0 MPa. If your load requirements are lower, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, which might save space and air consumption. The 10 mm adjustment range here is highly valuable for dialing in exact end positions during machine setup without needing to physically swap out a massive actuator.
Because this unit features a 650 mm stroke, the extended 40 mm rod is subject to significant side-loading risks; an external guide mechanism is strongly recommended to prevent premature seal wear. Note that the rear adjuster acts strictly as a travel stop and does not lock the load—if you need to hold position without live air pressure, consider the SAIL or BSAI series instead. It uses a PT tapered port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200X650-10 FAQ
At its maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 650 mm nominal stroke by up to 10 mm, providing a usable travel window of 640-650 mm. It is designed for fine-tuning the retract end position during setup and is not a locking device.
