About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-40S
The AirTAC SAIJ100X200-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 160-200 mm usable travel window, allowing you to dial back the nominal 200 mm stroke by up to 40 mm during commissioning.
This adjustable stopper lets you fine-tune the retract end position without swapping the cylinder or adding external stops. The rear adjuster acts only as a travel stop and deceleration point, not a lock, so it will not hold a load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series.

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 SAIJ100AX200-40S Is Used
Machine Changeover
Dial in the 160-200 mm travel window instantly when switching product sizes on a packaging line, eliminating the need to swap out physical spacer shims.
End-Position Tuning
Fine-tune the retract stroke during commissioning to perfect a pressing operation, using the rear screw to dial back the stroke by exactly 40 mm.
Variable Diverter Stops
Adjust the physical stopper position on the fly to handle varying package lengths on a conveyor system without reprogramming the machine logic.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-40S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust (5497 N at 0.7 MPa) alongside precise end-position tuning. If your setup needs less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas a 125 mm bore provides 8590 N for heavier loads. An adjustable stroke is preferred over a fixed SAI cylinder for machines requiring product changeovers or variable end-stops.
To replace an ISO 15552 cylinder, match the 100 mm bore, 200 mm stroke, 40 mm adjustment, PT tapered ports, and the -S magnet. The mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The 25 mm rod and M20x1.5 thread handle high side loads, but for this 200 mm stroke, external guidance is recommended for heavy lateral forces.
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 SAIJ100AX200-40S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm from the 200 mm nominal length, providing a 160-200 mm travel window. It acts as a mechanical stop and does not hold the load without live air pressure.
