About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X600-50S
The AirTAC SAIJ200X600-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches. By turning the external rear screw, you achieve a usable travel window of 550 to 600 mm, allowing precise end-position tuning without swapping out the entire actuator.
This bore size features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high flow demands. While the adjustable stopper fine-tunes the retract position, it acts only as a travel stop and does not hold the load without live air. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 SAIJ200X600-50S Is Used
Heavy Press Tuning
Dial in the exact 550-600mm end position during heavy press commissioning to accommodate material thickness variations without machining custom spacers.
Large Format Changeover
Adjust the retract stop on the fly when switching between large product sizes on an assembly line, utilizing the 50mm trim range for rapid setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X600-50S the Right Cylinder?
The adjustable stroke is chosen for commissioning fine-tuning or product-size changeovers, providing a 550-600mm travel window without adding external stops. For a direct ISO 15552 replacement match, verify the 600mm stroke, 50mm adjustment, G3/4 PT port, and the -S magnet requirement.
Because the 600mm stroke is substantial, the 40mm rod will experience significant leverage under side loading; an external guide rail is strongly recommended to prevent premature seal wear. Furthermore, the rear adjuster and variable air cushions only decelerate the travel end—they do not function as a lock. For load-holding without live air pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve.
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 SAIJ200X600-50S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke by up to 50mm, creating a usable travel window of 550 to 600mm. It only sets the end position and does not lock the load without continuous air pressure.
