About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-10S
The AirTAC SAIJ200X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 790-800 mm for precise end-position tuning. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty automation. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables position detection with CMSE reed or DMSE electronic switches.
This model features a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm air cushions at both ends to manage high kinetic energy. The PT tapered port thread ensures a reliable pneumatic seal. Because the rear adjuster acts solely as a mechanical stop to set deceleration limits, it does not hold the load without live air pressure; for fail-safe load holding, consider an external rod lock or the related SAIL pneumatic lock series.

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 SAIJ200X800-10S Is Used
Heavy Press Tuning
Dial in the exact bottom position of an 800 mm stroke press within a 790-800 mm window to accommodate material thickness variations without repositioning the cylinder.
Large Mold Changeover
Adjust the retract stopper up to 10 mm during product line changeovers to seat heavy molds accurately, avoiding the need to swap out the entire actuator.
Guided Load Positioning
Move large structural components along an 800 mm path, using the rear stop to set the precise end-of-stroke datum while external rails manage the side load.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-10S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires extreme force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 10 mm adjustment range is ideal for fine-tuning the final end position during commissioning without adding external stops. When replacing an ISO 15552 cylinder, match the 800 mm stroke, 10 mm adjustment, PT port thread, and -S magnet requirement. Note that SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
With an 800 mm stroke, the 40 mm rod is subject to significant side loads if the payload is unsupported. An external guide rail is strongly recommended to prevent rod binding and premature seal wear. The operating speed for this bore is 30-500 mm/s, constrained by the large internal volume and mass.

- ✓ 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 SAIJ200X800-10S FAQ
At the maximum rated pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm, creating a 790-800 mm usable stroke window. This stopper fine-tunes the end position at commissioning but does not lock the load without continuous air pressure.
