About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-75S
The AirTAC SAIJ100X350-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 275 to 350 mm, allowing you to dial back the nominal 350 mm stroke by up to 75 mm during commissioning.
This SKU is configured with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a piston magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G1/2 PT tapered ports ensure high flow capacity for its 30-800 mm/s speed range.

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 SAIJ100AX350-75S Is Used
Variable End-Stop Machining
Fine-tune the 275-350 mm travel window to accommodate varying raw material lengths on machining centers without repositioning the cylinder body.
Product Changeover Diverter
Adjust the retract stroke up to 75 mm on packaging lines to handle different carton sizes on the fly, ensuring accurate diverting without mechanical rebuilds.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-75S the Right Cylinder?
Choose this adjustable-stroke model when an application requires frequent end-position tuning or product-size changeovers without swapping cylinders or adding external stops. If you need less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa; if you require more, an 125 mm bore provides 6136 N. Because the 350 mm stroke is relatively long, an external guide is recommended to manage side loads on the 25 mm rod.
The rear adjuster acts strictly as a travel stop and works with the air cushions to decelerate the load, but it will not hold the position without live air pressure. For true load-holding without continuous air, select an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder. To replace an ISO 15552 cylinder, match the 100 mm bore, 350 mm stroke, 75 mm adjust, G1/2 PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet.
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 SAIJ100AX350-75S FAQ
At 0.9 MPa, the push force increases to 7068 N.
A rear adjusting screw acts as a stopper, allowing you to shorten the effective stroke from its 350 mm nominal length down to 275 mm. This provides a 75 mm tuning window for precise end-position setup without changing the cylinder.
