About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-20S
The AirTAC SAIJ200X280-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions.
This heavy-duty unit features a carbon steel rod and PT tapered port threads. It includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves. The rear adjuster acts strictly as a travel stop for deceleration and positioning, not a lock, meaning it cannot hold a 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 SAIJ200X280-20S Is Used
Press Stroke Tuning
Dial in the exact 260-280 mm end-of-stroke position for heavy pressing applications without physically swapping the cylinder or adding mechanical shims.
Product Changeover Lines
Quickly adjust the retract stop to accommodate different product sizes on automated assembly lines, reducing downtime between production runs.
Long-Stroke Guiding
Leverage the 40 mm carbon steel rod for high side-load resistance on 280 mm strokes, while using an external guide for precise heavy-load tracking.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-20S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires massive thrust—up to 15708 N at 0.5 MPa or 21991 N at 0.7 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, while stepping up is unnecessary unless exceeding the 200 mm class. The adjustable 260-280 mm window is ideal for variable product sizes or machine changeover, providing a distinct advantage over a fixed-stroke SAI cylinder.
Because this model has a 280 mm stroke, the 40 mm rod diameter and M36x2 thread provide substantial support, but long unsupported strokes still require an external guide to prevent side-loading damage. For true load-holding without continuous air pressure, this standard SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock variants instead. As a dimensionally interchangeable ISO 15552 profile cylinder, it uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200X280-20S FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 280 mm down to 260 mm. This creates a 260-280 mm adjustable window for fine-tuning end positions without changing the cylinder.
