About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-40
The AirTAC SAIJ100X900-40 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to fine-tune the retract end-position during commissioning. Rather than relying on external stops, the integrated 40 mm adjustment screw lets you dial back the 900 mm nominal stroke, providing a usable travel window of 860 to 900 mm to perfectly accommodate product size changeovers.
The extruded aluminum barrel includes dual sensor grooves, and while no magnet is specified here, adding a -S magnet enables precise position detection via AirTAC CMSE reed or DMSE electronic solid-state 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 SAIJ100AX900-40 Is Used
Machine Changeover
Dial in the 860-900 mm retract position instantly when switching a packaging line to a different pallet size, avoiding the need to physically swap cylinders or bolt on external stopper blocks.
End-Position Tuning
Fine-tune the final resting position of a heavy press or lifting mechanism during commissioning using the 40 mm rear adjustment screw to compensate for mechanical tolerance stack-up.
Variable Product Stops
Act as an adjustable diverter gate on a material handling conveyor, where the exact retraction distance needs to be tweaked on the fly to accommodate varying package widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-40 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires substantial thrust—stepping up from a 63 mm bore yields 2805 N at 0.5 MPa, while dropping to an 80 mm bore provides 2268 N of pull force at the same pressure. The adjustable stroke is ideal for machine setups requiring variable end stops without swapping out the entire cylinder body.
Because the total stroke is 900 mm, an external guide is strongly recommended to prevent rod sag and premature seal wear from excessive side loading. To match this ISO 15552 footprint, specify a 100 mm bore, 900 mm stroke, 40 mm adjustment, PT tapered port threads, and your required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember, the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, select an SAIL or BSAI series cylinder 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 SAIJ100AX900-40 FAQ
It operates efficiently at speeds between 30 and 800 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 900 mm nominal stroke by up to 40 mm, giving an effective travel range of 860 to 900 mm. It only decelerates and sets the travel end; it does not lock or hold the load without continuous air pressure.
