About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-20S
The AirTAC SAIJ200X30-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. With a nominal 30 mm stroke and a 20 mm adjustment code, the effective travel window can be fine-tuned down to 10 mm, giving you precise control over short, high-force movements.
This adjustable stopper allows you to dial in the exact retract end-position during commissioning without swapping out the cylinder or adding external stops. The extruded aluminum barrel integrates sensor grooves on both sides, and the carbon steel rod with an M36x2 thread provides a robust interface for heavy-duty tooling. Note that the rear adjuster acts only as a travel stop and does not hold the 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 SAIJ200X30-20S Is Used
Machine Changeover
Quickly fine-tune the end-stop position during product size changes without removing the cylinder or bolting on external mechanical stops.
Short-Stroke Clamping
Provides massive holding force in compact spaces, using the rear adjuster to set the exact 10-30 mm clamping distance for varying part thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-20S the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeover, allowing the end-stop to be trimmed back by up to 20 mm without changing the mounting footprint. For load-holding without continuous air pressure, this cylinder is not a lock; consider an AirTAC SAIL or BSAI model instead.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard mounting interfaces using a PT tapered G3/4 port. It uses the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The standard carbon steel rod and -S magnet configuration ensure compatibility with DMSE solid-state sensors for precise position feedback.

- ✓ 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 SAIJ200X30-20S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 10 to 30 mm, enabling fine-tuning of the end position at commissioning without external stops.
