About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X600-20
It features a carbon steel piston rod and a PT tapered G3/4 port to handle substantial air flows efficiently.
This model integrates a rear stroke adjuster that creates a 580-600mm usable travel window, allowing you to trim the 600mm nominal stroke by up to 20mm. Unlike a fixed-stroke SAI cylinder, this external stopper lets you fine-tune the retract end position during commissioning without adding external stops. The adjuster acts strictly as a travel deceleration point, not a load lock, so live air is always required to hold position.

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 SAIJ200X600-20 Is Used
Heavy Press Tuning
Dial in the exact 580-600mm retraction point on a large forming press during setup, absorbing impact via the 50mm cushion while avoiding hard mechanical crashes.
Product Size Changeover
Adapt a heavy-duty automated line to new part dimensions by turning the rear adjuster up to 20mm, eliminating the need to physically swap out a 600mm cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X600-20 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme thrust, such as 21991N at 0.7MPa, and precise end-position tuning. If your force requirements are lower, stepping down to a 160mm bore provides 10053N at 0.5MPa, which may save space and air consumption. The adjustable 580-600mm window is ideal for product changeovers where exact retraction limits vary slightly.
Because the 600mm stroke is substantial, the 40mm carbon steel rod and M36x2 thread need external guide support to prevent excessive side-loading and rod deflection. For position feedback, you would need the -S magnet variant to use CMSE reed or DMSE electronic sensors in the dual sensor grooves. If your setup requires holding loads without continuous air pressure, consider an external rod lock or the AirTAC SAIL lock cylinder instead of relying on this adjuster. This profile cylinder is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200X600-20 FAQ
If you increase the pressure to 0.7MPa, the push force rises to 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the 600mm nominal stroke by up to 20mm, creating a 580-600mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
