About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-40S
The AirTAC SAIJ100X220-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 220 mm travel by up to 40 mm. This yields a usable end-position window of 180 to 220 mm, which is ideal for fine-tuning machinery during commissioning or product changeovers without swapping out the physical unit. It delivers robust thrust, pushing 7068 N at 0.9 MPa and pulling 3681 N at 0.5 MPa.
This specific configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes an integrated magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit is fitted with PT tapered ports (G1/2) along with adjustable air cushions at both ends to manage impact loads.

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 SAIJ100AX220-40S Is Used
Machine Setup & Changeover
Fine-tune the 180-220 mm end-stop during line changeovers to accommodate different product widths without physically replacing the cylinder.
Variable End-Position Tuning
Dial in the exact retraction point during commissioning using the rear screw, avoiding the need for external stopper blocks on the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-40S the Right Cylinder?
The adjustable 180-220 mm stroke window is selected over a fixed-stroke SAI cylinder when a machine requires variable end-stops to accommodate multiple product sizes on a single line. Because the nominal stroke is 220 mm, you should verify side-load conditions and utilize an external guide if the load is unsupported.
For direct replacements, match the 100 mm bore, 220 mm stroke, 40 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster and air cushions function only as travel stops and deceleration devices; they do not hold the load without live air. For position holding without pressure, use an external rod lock or pilot-operated check valve.
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 SAIJ100AX220-40S FAQ
The rear adjusting screw acts as an external stopper that can shorten the effective travel by up to 40 mm. This creates a usable stroke window of 180 to 220 mm, allowing you to set the exact end position without changing the cylinder.
