About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-100
The AirTAC SAIJ100X350-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 250-350 mm usable travel window, allowing you to dial back the 350 mm nominal stroke by up to 100 mm during commissioning.
This unit is built with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks the -S magnet required for AirTAC CMSE or DMSE switches. The rear adjuster functions strictly as a travel stop to fine-tune end positions, not as a lock.

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 SAIJ100AX350-100 Is Used
Machine Setup Changeover
Fine-tune the 250-350 mm travel window during product line changeovers to accommodate different package sizes without adding external mechanical stops.
Variable End-Stop Positioning
Dial in the exact retraction point for diverter arms on a conveyor, adjusting the 100 mm range on the fly to handle varying product widths.
Commissioning Stroke Tuning
Trim the forward stroke during initial machine commissioning to perfect the end-of-travel position for a 3927 N pressing application.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-100 the Right Cylinder?
Select this adjustable model when a process requires variable end-stops or frequent product-size changeovers without physically swapping cylinders. For higher force, a 125 mm bore provides 6136 N. To replace an existing ISO 15552 cylinder, match the 100 mm bore, 350 mm stroke, 100 mm adjustment, PT ports, and desired mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the nominal stroke is 350 mm, the 25 mm piston rod and M20x1.5 rod thread should be paired with an external guide to prevent excessive side-loading. Note that this cylinder does not hold loads without live air; for pilot-operated locking, consider the SAIL or BSAI series 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 SAIJ100AX350-100 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 350 mm nominal stroke by up to 100 mm, creating a 250-350 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
