About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-50
The AirTAC SAIJ100X290-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This unit is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads (G1/2). The rear adjustment screw acts purely as a travel stop to set end positions; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX290-50 Is Used
Product Changeovers
Dial in the 240-290mm travel window during format changes on packaging lines, avoiding the need to physically swap out the cylinder for different package sizes.
End-Position Tuning
Fine-tune the retract stopper at machine commissioning to perfect the seating of heavy components, using the rear screw rather than adding external mechanical stops.
Variable End Stops
Adapt automated assembly stations on the fly by adjusting the effective stroke up to 50mm, providing flexibility for multiple product variants on one line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX290-50 the Right Cylinder?
The 50mm adjustment range is ideal for product changeovers on a line, allowing you to shorten the stroke without swapping the cylinder or adding external stops.
Because the 290mm stroke is 300mm or under, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads. This SKU is dimensionally interchangeable per ISO 15552. To match this exact configuration, specify a 100mm bore, 290mm stroke, 50mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet.
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 SAIJ100AX290-50 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 290mm stroke by up to 50mm, providing an effective travel window of 240-290mm. It only sets the end position and does not hold the load without live air pressure.
At 0.7 MPa, the push force increases to 5497N.
