About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-20S
The AirTAC SAIJ100X200-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 180-200 mm usable travel window, allowing you to dial back the nominal 200 mm stroke by up to 20 mm during commissioning. It delivers robust thrust, pushing 3927 N at 0.5 MPa and 7068 N at 0.9 MPa, making it ideal for heavy-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance and includes a piston magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ100AX200-20S Is Used
Machine Setup Tuning
Dial in the exact 180-200 mm end-stop during initial commissioning to perfect a pressing operation without machining new spacers.
Product Changeover
Quickly adjust the retract position by up to 20 mm on a packaging line when switching to a slightly shorter carton size.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-20S the Right Cylinder?
Select this 100 mm bore when your application requires more force than a 63 mm cylinder (1559 N at 0.5 MPa) but less than the massive 125 mm class (6136 N at 0.5 MPa). The adjustable stroke is chosen over a fixed SAI cylinder when you need fine end-position tuning at machine setup or product changeover without swapping the physical cylinder or adding external stops. To replace this ISO 15552 cylinder, match the 100 mm bore, 200 mm stroke, 20 mm adjustment, PT tapered ports, and the -S magnet option.
Because the nominal stroke is 200 mm, you should evaluate the load for potential side-loading. The 25 mm rod and M20x1.5 thread handle substantial loads, but long unsupported strokes still require an external guide. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, use a SAIL lock, BSAI clamp-lock, or an external rod lock.
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 SAIJ100AX200-20S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 200 mm nominal stroke down to 180 mm. It sets the end position but does not lock the load without live air pressure.
