About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-75S
The AirTAC SAIJ200X650-75-S is a double-acting ISO 15552 profile cylinder featuring a robust 200 mm bore and a 650 mm stroke. A rear-mounted adjusting screw allows you to fine-tune the retract end-position, creating a usable travel window between 575 and 650 mm.
Because this is an extruded aluminum profile cylinder, it includes sensor grooves on both sides for straightforward switch mounting. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors for precise position feedback. An adjustable air cushion at both ends decelerates the rod safely, though the rear stopper acts only as a travel limiter 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 SAIJ200X650-75S Is Used
Heavy Press Positioning
Fine-tune the 575-650 mm travel window during setup to precisely position large pressing equipment without mechanical shims.
Automotive Assembly Line
Accommodate different chassis lengths on a single conveyor by adjusting the rear stopper during product changeovers.
Large Fixture Calibration
Dial in the exact end-of-stroke for heavy testing fixtures, using the 40 mm rod to withstand high side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-75S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust, stepping up from a 160 mm bore that yields 10053 N at 0.5 MPa. The 75 mm adjustment range is ideal for heavy machinery commissioning, allowing you to dial in the exact end-stop without swapping hardware. If you need to hold a suspended load safely without continuous air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster is a stop, not a brake. For ISO 15552 replacement matching, specify: 200 mm bore, 650 mm stroke, 75 mm adjust, PT G3/8 ports, and the -S magnet. Given the 650 mm stroke, an external guide is recommended to prevent excessive side-load wear on the 40 mm carbon steel rod.
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 SAIJ200X650-75S FAQ
It can reach a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 650 mm stroke by up to 75 mm, creating a usable travel window of 575 to 650 mm. This allows precise end-position tuning at commissioning without adding external stops.
