About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-30S
The AirTAC SAIJ200X500-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state switches mounted into the dual sensor grooves on the extruded aluminum barrel.
This model features a 500mm nominal stroke paired with a 30mm adjustment range, creating a usable travel window of 470-500mm. This built-in rear stopper allows precise end-position tuning during commissioning without adding external stops. The robust 40mm carbon steel rod and M36x2 thread handle heavy loads, while standard PT tapered ports and variable air cushions at both ends ensure controlled deceleration.

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 SAIJ200X500-30S Is Used
Heavy Press Tuning
Dial in the exact 470-500mm end position during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Adjust the rear stopper on the fly for different pallet sizes on a high-thrust conveyor line, utilizing the 30mm travel window for rapid format changes.
Large Assembly Jigs
Secure massive components in automated assembly jigs where the 15708N baseline thrust at 0.5 MPa is required, using the rear screw to set precise clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-30S the Right Cylinder?
The 30mm adjuster is ideal for fine-tuning product changeovers, whereas a fixed-stroke SAI lacks this commissioning flexibility. Because the nominal stroke is 500mm, an external guide is recommended to manage side-load forces on the extended rod.
For an exact ISO 15552 replacement match, specify the 200mm bore, 500mm stroke, 30mm adjustment, PT port thread, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ does not hold loads without live air. For load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200X500-30S FAQ
At 0.9 MPa, the push force increases to 28274N.
The rear adjuster acts as an external stopper, allowing you to shorten the effective travel from the 500mm nominal stroke down to 470mm. It sets the retract end position but does not lock the load without live air pressure.
