About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X70-10
A rear mechanical stopper allows you to fine-tune the effective stroke, providing a usable travel window of 60-70mm for precise end-position calibration during commissioning.
This large-bore pneumatic actuator features a robust 40mm carbon steel rod and a G3/4 PT tapered port to ensure high flow rates for rapid actuation. The extruded aluminum barrel incorporates dual-sided sensor grooves, and the adjustable rear stop acts purely as a travel limiter—it does not lock or hold the load without live air pressure.

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 SAIJ200X70-10 Is Used
Heavy Press Tuning
Dial in the exact 60-70mm travel distance for high-force pressing operations, allowing precise calibration without machining custom external spacers.
Product Changeover
Quickly adapt the end-stop position on automated assembly lines when switching to a new product variant, minimizing downtime and retooling.
Short-Stroke Clamping
Provide massive 15708N clamping force for heavy industrial fixtures, using the rear adjuster to compensate for material thickness variations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X70-10 the Right Cylinder?
Selecting this 200mm bore actuator is ideal when your machinery requires extreme thrust, such as 15708N at 0.5MPa, but only needs a short 60-70mm adjustable stroke. If your force requirements are lower, stepping down to a 160mm bore yields 10053N at 0.5MPa, which may save space and air consumption. Choose this SAIJ adjustable variant over a fixed-stroke SAI cylinder when you need on-the-fly end-stop tuning for product changeovers without swapping the actuator.
For ISO 15552 replacement matching, verify the 200mm bore, 70mm nominal stroke, 10mm adjustment range, G3/4 PT port, and the required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since the 40mm rod is substantial, ensure your external guidance handles any side loads. To hold a load securely without live air, use a SAIL or BSAI cylinder instead of relying on this stopper.
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 SAIJ200X70-10 FAQ
The operating speed ranges from 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 70mm nominal stroke by up to 10mm, creating a 60-70mm usable travel window. It only sets the end position and does not hold the load without air pressure.
