About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-100S
The AirTAC SAIJ100X500-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 400 to 500 mm for precise end-position tuning. This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with CMSE reed and DMSE electronic sensors.
The integrated rear stopper allows you to dial back the stroke by up to 100 mm during commissioning or product changeovers without swapping the cylinder or adding external stops. It uses a G1/2 port and supports a speed range of 30-800 mm/s. Remember that this rear adjuster acts strictly as a travel stop and deceleration point, not a load-holding lock; maintaining position requires live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX500-100S Is Used
Variable End-Stop Machining
Fine-tune the 400-500 mm travel window on the fly to accommodate different part lengths during short-run machining operations without changing tooling.
Product Size Changeovers
Rapidly adjust the rear stopper by up to 100 mm to handle varying package dimensions on a packaging line, ensuring precise positioning without external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-100S the Right Cylinder?
The adjustable stroke is ideal for machinery requiring variable end stops or frequent size changeovers, eliminating the need to stock multiple fixed-stroke SAI cylinders. To match this ISO 15552 footprint exactly, specify the 100 mm bore, 500 mm stroke, 100 mm adjustment, PT tapered ports, and the -S magnet.
Because this cylinder features a 500 mm stroke, the 25 mm rod and M20x1.5 thread provide sturdy support, but an external guide is highly recommended to prevent excessive side-loading on long unsupported travels. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, deliberately omitting FB, CA, CB, and CR options. If your application requires true load-holding without continuous air pressure, consider the SAIL or BSAI locking cylinder variants instead.
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 SAIJ100 Adjustable Cylinder SAIJ100AX500-100S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 500 mm down to 400 mm. This creates a 400-500 mm usable window for fine-tuning the end position at commissioning, but it functions as a stop and does not hold the load without live air pressure.
