About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30S
The AirTAC SAIJ200X500-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30mm of end-position tuning. This yields a usable travel window of 470-500mm, letting you dial in the exact retract distance during commissioning without adding external stops. It delivers massive thrust, pushing 21991N and pulling 15080N at 0.7 MPa, while the M36x2 rod thread and 40mm diameter rod handle high side loads.
This unit includes a magnet for CMSE and DMSE sensors, with the rod machined from SUS420J2 stainless steel for enhanced corrosion resistance. The extruded aluminum barrel integrates sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop and deceleration point; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 470-500mm retract position during heavy press setup, accommodating material thickness variations without swapping cylinders.
Product Size Changeover
Adjust the rear stopper quickly when switching between product sizes on a large assembly line, minimizing machine downtime.
Large Fixture Positioning
Position heavy manufacturing fixtures precisely using the 21991N push force, relying on the M36x2 rod for structural stability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30S the Right Cylinder?
Choose this 200mm bore when your application requires over 21000N of push force at 0.7 MPa, stepping up from a 160mm bore that provides 14074N. The adjustable 470-500mm travel is ideal for product-size changeovers, allowing you to fine-tune the retract end-stop on the machine without physically swapping the cylinder. For load-holding without continuous air pressure, this cylinder is insufficient—the rear adjuster is a stop, not a lock, so you would need an external rod lock or a SAIL pneumatic lock cylinder.
Configuration matches: 200mm bore, 500mm stroke, 30mm adjustment, PT tapered port threads, SUS420J2 stainless steel rod, and a -S magnet. Because the 500mm stroke is substantial, always guide the load externally to prevent binding and protect the rod seals from excessive side-load wear.
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 SAIJ200AX500-30S FAQ
At 0.7 MPa, this 200mm bore cylinder provides 21991N of push force and 15080N of pull force. The operating speed range is 30-500 mm/s.
The rear adjuster allows you to shorten the nominal 500mm stroke by up to 30mm, creating a usable travel window of 470-500mm. It functions as a travel stop and does not lock the load without live air pressure.
