About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-50S
The AirTAC SAIJ200X700-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel.
This specific SKU features a 700 mm nominal stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 650 to 700 mm. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. The carbon steel rod with its M36x2 thread provides high rigidity, though a 700 mm stroke requires an external guide to manage side loads.

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 SAIJ200X700-50S Is Used
Heavy Press Tuning
Fine-tune the 650 to 700 mm stroke end-position during machine commissioning to apply precise clamping force on large assemblies.
Product Changeover
Quickly adapt the retract end-stop for varying product sizes on a high-thrust line without physically swapping out the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-50S the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires extreme thrust—up to 15708 N at 0.5 MPa—and a variable end-stop. The SAIJ design allows precise end-position tuning during product changeovers, whereas a fixed-stroke SAI cylinder lacks this built-in flexibility. Remember that the rear adjuster only sets the travel end; it does not hold the load without live air. For load-holding without pneumatic pressure, select the SAIL or BSAI series instead.
When matching an ISO 15552 replacement, specify a 200 mm bore, 700 mm stroke, a 50 mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR brackets.
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 SAIJ200X700-50S FAQ
The rear adjuster lets you mechanically shorten the 700 mm nominal stroke by up to 50 mm, creating a usable travel window of 650 to 700 mm. It acts as a travel stop and does not lock the load without live air.
