About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-75S
The AirTAC SAIJ100X220-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 145 to 220 mm. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
This adjustable-stroke variant allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping out the entire cylinder. It features a G1/2 port and a variable air cushion at both ends to manage deceleration. The rear adjuster functions strictly as a mechanical stop to set the travel limit, not as a locking mechanism.

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 SAIJ100AX220-75S Is Used
Product Changeover
Dial in the exact retract distance from 145 to 220 mm on packaging lines running different carton sizes without changing hardware.
End-Position Tuning
Fine-tune the final stopping point of a 3927 N press operation during machine commissioning to perfect the assembly tolerance.
Variable End Stops
Use the 75 mm adjustment window to create a programmable mechanical stop for testing components across multiple travel distances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX220-75S the Right Cylinder?
The 75 mm adjustment range is ideal for machinery requiring variable end-stops to handle multiple product sizes on a single line. For fixed-travel needs without the adjusting screw, the standard SAI cylinder is a simpler alternative.
Because the 220 mm stroke approaches the mid-range of standard lengths, ensure the M20x1.5 rod thread and 25 mm rod diameter are supported by an external guide if the load imposes significant lateral forces. This SAIJ model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Note that the rear adjuster and air cushion will not hold a load without live air; for true position holding, consider the SAIL or BSAI series.
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 SAIJ100AX220-75S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 220 mm stroke by up to 75 mm. This creates a usable travel window of 145 to 220 mm, but it does not lock the load without continuous air pressure.
