About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX35-10
The AirTAC SAIJ40X35-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated -10 adjustment mechanism allows you to trim the nominal 35mm stroke back by up to 10mm, creating a precise 25-35mm usable travel window for exact end-position tuning.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific SKU is supplied without a magnet. The rear stopper screw simply dials in the retract distance during commissioning without requiring external physical stops.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40AX35-10 Is Used
Precision Actuation Tuning
Dial in the exact 25-35mm travel distance during machine commissioning to accommodate minor mechanical tolerances without disassembling the assembly.
Product Changeover Stops
Quickly adjust the retract end-position on a packaging line when switching between slightly different product sizes that require varying stroke depths.
Corrosion-Resistant Forming
Leverage the SUS420J2 stainless steel rod in light metalworking or welding cells where moisture and minor splatter could degrade standard carbon rods.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX35-10 the Right Cylinder?
If your force requirements are lower, stepping down to a 32mm bore yields 563N at 0.7 MPa, while moving up to a 50mm bore provides 1374N. The SAIJ series allows you to fine-tune the travel window without physically swapping out the cylinder.
Because the 35mm nominal stroke is short, side-loading is minimal, but the 16mm rod and M12x1.25 thread still handle moderate lateral stresses well. Remember that the rear adjuster acts purely as a travel stop and does not lock the load; if you need fail-safe load holding without live air pressure, consider the SAIL or BSAI series. This cylinder uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ40 Adjustable Cylinder SAIJ40AX35-10 FAQ
It features a rear adjuster screw that lets you shorten the nominal 35mm stroke by up to 10mm. This provides a usable travel window of 25-35mm, allowing you to fine-tune the end position during setup. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
If you increase the pressure to 0.7 MPa, the push force rises to 879N.
