About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-100S
The AirTAC SAIJ100X950-100-S is a double-acting ISO 15552 profile cylinder featuring a double rod and a rear stroke adjuster. The built-in magnet supports position sensing, and the rod is constructed from SUS420J2 stainless steel for enhanced durability against corrosion and side-load wear.
This model provides a 950mm nominal stroke that can be dialed back by up to 100mm, creating an 850-950mm usable travel window. This rear stopper lets you fine-tune the retract end-position during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.

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 SAIJ100AX950-100S Is Used
Machine Changeovers
Dial the travel window back by up to 100mm during product line changeovers to set new end positions without machining new hard stops.
Long-Stroke Diverters
Fine-tune the retract position of a 950mm diverter arm to accommodate varying package sizes on a conveyor line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-100S the Right Cylinder?
An adjustable stroke is ideal for product-size changeovers on a line, allowing you to dial in the 850-950mm travel window on the fly. To replace an ISO 15552 cylinder, match the 100mm bore, 950mm stroke, 100mm adjustment, PT tapered G1/2 port, and the -S magnet.
Because the stroke is 950mm, long unsupported travel demands an external guide to prevent rod sagging and premature seal wear. The rear adjuster acts only as a travel stop and relies on the air cushion for deceleration; it does not hold the load without live air. For true load-holding without pressure, select an external rod lock or pilot-operated check valve. SAIJ uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAIJ100AX950-100S FAQ
At 0.9MPa, the push force increases to 7068N.
A rear adjusting screw acts as a stopper, allowing you to shorten the 950mm nominal stroke by up to 100mm, yielding an 850-950mm adjustable travel window. It only sets the end position and does not lock the load.
