About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-100S
The AirTAC SAIJ200X450-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a standard carbon steel piston rod and a built-in magnet for position sensing. By integrating a rear stopper screw, this model allows you to dial back the nominal 450 mm stroke by up to 100 mm, creating a flexible 350-450 mm usable travel window without changing the cylinder body.
The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Unlike fixed-stroke SAI cylinders, this adjustable variant eliminates the need for external mechanical stops during machine commissioning or product size changeovers.

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 SAIJ200X450-100S Is Used
Heavy Press Changeover
Quickly reconfigure the end-stop from 450 mm down to 350 mm when switching between heavy product sizes on a high-tonnage press line.
Large Fixture Tuning
Fine-tune the clamping travel during machine commissioning to perfectly seat large automotive or structural components without adding external spacers.
Heavy Material Positioning
Adjust the pusher stroke on the fly to accurately index heavy pallets or steel plates of varying widths down a conveyor.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-100S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application demands up to 3204 kgf of force alongside a variable end-stop. The PT tapered port thread matches standard pneumatic fittings securely.
Because the 450 mm stroke is relatively long, an external guide is strongly recommended to prevent excessive side-loading on the 40 mm diameter carbon steel rod. The rear adjuster acts strictly as a travel stop to fine-tune the 350-450 mm window; it does not lock or hold the load without live air. For fail-safe load holding without pneumatic pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This SAIJ model uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200X450-100S FAQ
At its maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf of thrust.
The rear adjuster screw allows you to mechanically shorten the effective travel from the 450 mm nominal stroke down to as little as 350 mm. This creates a 350-450 mm usable window, enabling precise end-position tuning during commissioning without replacing the cylinder.
