About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-30S
The AirTAC SAIJ200X65-30-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. Equipped with a rear mechanical adjuster, it provides a usable travel window of 35-65 mm, allowing you to dial in the exact end position without swapping hardware. It delivers substantial thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, reaching a maximum of 3204 kgf at 1.0 MPa.
This variant features a carbon steel rod and a PT tapered port thread. The integrated -S magnet supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches housed in the dual-side sensor grooves. As an extruded aluminum profile cylinder, it remains dimensionally interchangeable per ISO 15552 while offering a focused mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X65-30S Is Used
Heavy Press Tuning
Fine-tune the 35-65 mm pressing depth on heavy machinery during setup, ensuring exact clamping force without machining custom spacers.
Product Size Changeover
Adapt automated lines to varying product dimensions instantly by adjusting the rear stopper, minimizing downtime between production runs.
Heavy Load Positioning
Move massive components with up to 3204 kgf of force, relying on the 40 mm carbon steel rod to handle significant mechanical stress.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-30S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application demands extreme force—such as 15708 N at 0.5 MPa—that smaller bores cannot provide. If your setup requires less than 10053 N at 0.5 MPa, stepping down to the 160 mm bore saves space and air consumption. Choose this adjustable-stroke SAIJ model over a fixed SAI when you need on-the-fly end-position tuning during machine commissioning or product changeovers.
Because the nominal stroke is 65 mm, the 30 mm adjustment screw yields a versatile 35-65 mm travel window. Remember that the rear adjuster acts only as a travel stop to set deceleration alongside the air cushions; it is not a locking device. If your system must hold a load without continuous live air pressure, integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI locking cylinder.
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 SAIJ200X65-30S FAQ
At its maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to trim the 65 mm nominal stroke inward, creating a usable travel window of 35-65 mm. This stopper sets the retract end position but does not lock the load without live air pressure.
