About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-30S
The AirTAC SAIJ200X650-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows precise end-position tuning at commissioning without swapping cylinders or adding external stops.
It includes a -S magnet for position sensing and works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The carbon steel rod uses an M36x2 thread, and the rear stopper acts purely as a travel limit. It does not lock or hold the load without live air pressure, so you must maintain pneumatic supply during operation.

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 SAIJ200X650-30S Is Used
Heavy Press Tuning
Fine-tune the 620-650mm travel end-position during machine setup to perfectly seat heavy components without adding external physical stops.
Product Changeover
Quickly adjust the stroke end-limit by up to 30mm on automated lines when switching between slightly different large product sizes.
Heavy Automation
Drive massive 15708N loads in heavy-duty ISO 15552 setups while using the rear screw to dial in the exact retract distance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-30S the Right Cylinder?
Choose this 200mm bore when 160mm (9425N pull at 0.5MPa) is insufficient for your heaviest pushes. The adjustable 620-650mm window is ideal for product-size changeovers on a line, letting you dial in the exact end-stop without installing fixed spacers. If you need to hold position safely without live air, select the SAIL or BSAI series instead of relying on this stopper.
This SAIJ200X650-30-S is dimensionally interchangeable per ISO 15552. It features a PT tapered G3/4 port, carbon steel rod, and -S magnet. Because the 650mm stroke is long, the large M36x2 rod carries high side loads, but you should still use an external guide to prevent binding. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X650-30S FAQ
At the maximum 1.0MPa operating pressure, it delivers up to 3204kgf.
The rear adjuster screw lets you shorten the 650mm nominal stroke by up to 30mm, creating a 620-650mm usable travel window. This stopper only sets the end position; it does not lock the load without live air.
