About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-10
The AirTAC SAIJ200X270-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 270 mm travel back by up to 10 mm, yielding a precise 260-270 mm usable window for exact end-position tuning.
This model uses a PT tapered port and relies on extruded aluminum barrel construction with sensor grooves on both sides rather than traditional tie-rod assembly. The rear adjuster acts purely as a mechanical stop to set the retract position and must not be confused with a locking mechanism, as the cylinder cannot hold loads 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 SAIJ200X270-10 Is Used
Heavy Press Tuning
Dial in the exact 260-270 mm end-stop during heavy press commissioning to compensate for mechanical tolerance without swapping cylinders.
Assembly Station Setup
Fine-tune the retract position on heavy assembly lines, using the rear stopper to adjust the stroke window by up to 10 mm for product variations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-10 the Right Cylinder?
The 10 mm adjustable window is perfect for fine-tuning the end position during commissioning without adding external stops, whereas a fixed-stroke SAI cylinder lacks this setup flexibility.
Because this is a 270 mm stroke, an external guide is recommended to prevent excessive side-loading on the 40 mm rod. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a brake. To match this ISO 15552 interchangeable cylinder, specify the 200 mm bore, 270 mm stroke, 10 mm adjustment, PT port, and standard mounting set.
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 SAIJ200X270-10 FAQ
The operating speed range for this 200 mm bore cylinder is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that shortens the 270 mm nominal stroke by up to 10 mm, creating a 260-270 mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
