About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-30
The AirTAC SAIJ200X270-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, designed to fine-tune end positions during commissioning. It provides a usable travel window of 240-270mm, allowing you to dial back the 270mm nominal stroke by up to 30mm without adding external stops.
This extruded aluminum profile barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this specific configuration omits the -S magnet. The piston rod is carbon steel with an M36x2 thread, and the cylinder operates at 30-500mm/s. It uses a PT tapered port thread and includes adjustable air cushions at both ends to manage deceleration. The SAIJ mounting set omits FB, CA, CB, and CR options, utilizing Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

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 SAIJ200X270-30 Is Used
Product Changeover Systems
Allows operators to quickly dial in new retract end-stops during product family transitions on a line without physically swapping out the entire cylinder.
Large Material Handling
Handles substantial payloads using the 200mm bore class, relying on the PT tapered port and M36x2 carbon steel rod for robust, high-flow actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-30 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires the maximum thrust class—up to 15708N at 0.5MPa or 21991N at 0.7MPa. If your force requirements are lower, stepping down to a 160mm bore yields 14074N at 0.7MPa, which saves space and air consumption. Choose this adjustable SAIJ over a fixed-stroke SAI when you need precise retract-end tuning to accommodate product size changeovers on the line.
Because the nominal stroke is 270mm, an external guide is recommended to manage side loads and prevent rod deflection. The rear adjuster acts strictly as a mechanical stop for end-position tuning and works alongside the air cushion for deceleration; it is not a lock. If your application requires load-holding without live air pressure, consider the SAIL air-released lock or BSAI clamp-lock cylinders instead. This model is dimensionally interchangeable per ISO 15552.
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 SAIJ200X270-30 FAQ
The pull force at 0.5MPa is 15080N.
The rear adjuster screw lets you shorten the 270mm nominal stroke by up to 30mm, providing a usable travel window of 240-270mm. It functions as a mechanical stop for end-position tuning and does not hold the load without live air.
