About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-10S
The AirTAC SAIJ200X270-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By integrating an external adjusting screw at the rear, this 200mm bore unit allows you to fine-tune the end position without swapping out the entire actuator.
This specific SKU provides a 260-270mm usable travel window, letting you dial back the nominal 270mm stroke by up to 10mm during commissioning. It features a carbon steel rod and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this model includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.

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 SAIJ200X270-10S Is Used
Heavy Press Tuning
Dial in the exact 260-270mm end-of-stroke position during heavy press commissioning to accommodate material thickness variations without external stopper blocks.
Product Changeover
Quickly adjust the stroke window on a high-force assembly line when switching between product variants, saving downtime on physical actuator swaps.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring a variable end-stop, preventing the need to bolt on external stops or purchase a fixed-stroke SAI cylinder. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 200mm bore, 270mm stroke, 10mm adjustment, PT port thread, and the -S magnet.
Because the 270mm stroke is substantial, ensure adequate external guiding to handle side loads, as even the robust 40mm rod and M36x2 thread cannot support high lateral forces alone. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; this plain SAIJ will not hold a load without live air pressure, so consider an AirTAC SAIL or BSAI cylinder if true load-holding is required.
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 SAIJ200X270-10S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 270mm down to 260mm. This creates a 260-270mm usable window for fine-tuning the retract end position at commissioning, but it does not lock the load without continuous air pressure.
