About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-30
The AirTAC SAIJ200X700-30 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear adjusting screw that allows you to fine-tune the effective stroke, providing a usable travel window of 670 to 700 mm.
This 200 mm bore unit uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with a PT tapered G3/4 port to handle high airflow. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU omits the magnet, adding an -S suffix enables electronic DMSE or reed CMSE switches. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not 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 SAIJ200X700-30 Is Used
Heavy Press Tuning
Dial in the exact 670 to 700 mm end-stop during machine setup to accommodate varying material thicknesses in a high-tonnage forming press without external shims.
Product Changeover
Quickly adjust the retract position by up to 30 mm on a packaging line when switching to a different pallet or container size, minimizing downtime.
Large Assembly Calibration
Fine-tune the end of stroke on heavy automotive assembly tooling to ensure perfect component mating, relying on the 40 mm rod to handle substantial side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-30 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires exceptionally high force, as stepping down to a 160 mm bore drops the 0.5 MPa push force from 15708N to 10053N. An adjustable-stroke model is specifically chosen over a fixed SAI cylinder when you need precise end-position tuning during commissioning or frequent product changeovers without physically swapping the barrel or adding external stops. For load-holding requirements without live air pressure, note that the rear adjuster is only a travel stop; you would need to specify a SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead.
When matching this ISO 15552 replacement, verify the 200 mm bore, 700 mm stroke, 30 mm adjustment range, PT G3/4 port, and the standard carbon steel rod. Because the 700 mm stroke is substantial and the 40 mm rod is heavy, an external guide is strongly recommended to prevent side-load damage to the front cover and seals. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations.

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 SAIJ200X700-30 FAQ
The maximum thrust at 1.0 MPa is 3204 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 700 mm nominal stroke by up to 30 mm. This creates a usable travel window of 670 to 700 mm for fine-tuning end positions without replacing the cylinder.
