About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-50S
The AirTAC SAIJ100X325-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 275 to 325 mm, allowing you to dial back the 325 mm nominal stroke by up to 50 mm during commissioning.
Equipped with PT tapered G1/2 ports, this model supports AirTAC CMSE reed and DMSE electronic sensors via its dual-sided extruded aluminum barrel grooves. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops. It uses a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

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 SAIJ100AX325-50S Is Used
Variable End-Stop Tuning
Dial in the exact 275 to 325 mm travel distance during machine commissioning to perfect end-of-stroke positioning without swapping cylinders.
Product Changeover
Quickly adapt automated lines to new product sizes by adjusting the rear stopper screw, minimizing downtime between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-50S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, stepping up from a 63 mm bore that yields 2182 N at 0.5 MPa. An adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To match this exact unit, specify: 100 mm bore, 325 mm stroke, 50 mm adjustment, PT G1/2 port, SUS420J2 rod, and a -S magnet.
Because the nominal stroke is 325 mm, ensure adequate external guiding to handle potential side loads over this extended travel. Remember that the rear adjuster and air cushions only decelerate the load; they do not hold it without live air. For true load-holding without pressure, consider an external rod lock or a SAIL/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 SAIJ100 Adjustable Cylinder SAIJ100AX325-50S FAQ
It can reach a maximum of 801 kgf at 1.0 MPa.
The nominal stroke is 325 mm, but the rear adjuster allows you to shorten the effective travel by up to 50 mm. This creates a usable adjustable window of 275 to 325 mm.
