About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-20
It features a robust 40mm carbon steel rod and a PT G3/4 port to handle high air volumes. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a rear mechanical stopper, this model allows you to fine-tune the end position during commissioning without adding external stops. The -20 code provides an adjustable travel window, letting you trim the 500mm nominal stroke back by up to 20mm to achieve a precise 480-500mm range. This on-machine tuning is critical for heavy-duty setups where exact positioning is required.

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 SAIJ200X500-20 Is Used
Heavy Press Tuning
Dial in the exact 480-500mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Large Assembly Changeover
Adjust the rear stopper quickly on the factory floor when switching between large product sizes, ensuring precise positioning on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-20 the Right Cylinder?
Select this 200mm bore cylinder when an 160mm bore (providing 10053N at 0.5MPa) is insufficient for your load, or step down if 15708N is excessive. An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise machine setup. The PT tapered port thread ensures a metal-to-metal seal.
Because the stroke is 500mm, the long unsupported rod requires an external guide to prevent excessive side-loading and premature seal wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at 30-500mm/s.

- ✓ 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 SAIJ200X500-20 FAQ
At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 500mm nominal stroke by up to 20mm. This creates a usable travel window of 480-500mm, enabling fine end-position tuning without changing the cylinder.
