About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-30S
The AirTAC SAIJ200X275-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 245-275 mm usable travel window by allowing you to trim the nominal 275 mm stroke back by up to 30 mm. Belonging to the 200 mm bore class, it delivers massive thrust up to 15708 N at 0.5 MPa, making it ideal for heavy-duty press operations.
This variant features a carbon steel rod and includes a standard magnet (-S) compatible with AirTAC CMSE reed and DMSE solid-state sensors, which seat neatly into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster screw acts purely as a travel stop for end-position tuning, not as a load lock. For applications requiring position holding without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ200X275-30S Is Used
Heavy-Duty Pressing
Ideal for applying massive clamping or pressing force up to 15708 N, with a 245-275 mm travel window to dial in the exact crush depth.
Machine Commissioning
The 30 mm rear stopper screw allows operators to fine-tune the retract end position during setup without machining new hard stops.
Automated Assembly Lines
Handles large product changeovers smoothly by adjusting the end-of-stroke position to accommodate varying part sizes on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-30S the Right Cylinder?
The 30 mm adjustment range is highly advantageous during machine commissioning, allowing you to fine-tune the end stop without swapping out the cylinder or adding external stops.
Because the 275 mm stroke exceeds 300 mm is false here, but at this massive 40 mm rod diameter and heavy load class, guiding the rod to prevent excessive side-loading remains critical. This model uses PT tapered port threads and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552 without relying on tie-rod construction.
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 SAIJ200X275-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a 245-275 mm usable travel window. It acts as a mechanical stop to tune the end position and does not lock the load without live air.
The maximum thrust is 3204 kgf when operated at the 1.0 MPa pressure limit.
