About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-30
The AirTAC SAIJ200X30-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, featuring a rear stroke adjuster that permits precise end-position tuning. With a nominal 30 mm stroke and a 30 mm adjustment range, this model provides a usable travel window of 0-30 mm, allowing you to dial back the full stroke to zero without adding external stops.
This extruded aluminum profile cylinder omits the FB, CA, CB, and CR mounts, utilizing a focused mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) for streamlined integration. The 40 mm carbon steel rod and M36x2 thread provide robust resistance against side loads, while the 50 mm variable air cushions at both ends manage deceleration. The rear adjuster acts solely 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 SAIJ200X30-30 Is Used
Heavy Press Tuning
Dial in the exact 0-30 mm contact position during heavy press setup, ensuring precise clamping force without swapping out the entire cylinder body.
Product Size Changeover
Quickly adapt the end-stop for varying product heights on a packaging line, using the rear adjuster to trim the stroke safely down to zero for smaller items.
Machine Commissioning
Fine-tune the final end-of-stroke position during initial equipment build, compensating for mechanical tolerances without installing secondary external stoppers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-30 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force—stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N. An adjustable stroke is selected here over a fixed SAI cylinder when you need to fine-tune the exact endpoint during machine commissioning or product changeover. Because the usable travel window spans the entire 0-30 mm range, you can safely trim the full stroke to zero for delicate positioning tasks.
For true load-holding without continuous air pressure, this cylinder is insufficient; you must integrate an external rod lock, a pilot-operated check valve, or switch to the AirTAC SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, match your replacement by confirming the 200 mm bore, 30 mm stroke, 30 mm adjustment code, PT G3/4 port, and the required mounting interface. Note that sensors are not included, as no magnet (-S) is specified.

- ✓ 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 SAIJ200X30-30 FAQ
The rear adjuster screw allows you to shorten the effective travel from its nominal 30 mm down to 0 mm. This creates a 0-30 mm usable travel window for fine-tuning the end position at commissioning, acting as a stop rather than a load lock.
