About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-50S
The AirTAC SAIJ100X90-50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in magnet enables position detection with CMSE reed and DMSE electronic sensors.
With a 90 mm nominal stroke and a 50 mm adjustment code, this model provides a usable travel window of 40 to 90 mm. You can fine-tune the retract end position at commissioning without adding external stops. It uses a PT tapered G1/2 port and offers variable air cushioning at both ends.

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 SAIJ100AX90-50S Is Used
Product Changeovers
Quickly dial the stroke from 90 mm down to 40 mm to accommodate different product lengths on the same line without changing hardware.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfect seating against a part, avoiding the need for external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers, letting you dial back the 90 mm stroke to a 40 mm effective travel without swapping the cylinder. For a fixed end position without the adjusting screw, use the standard SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 50 mm adjustment, PT port, and -S magnet. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI cylinder.
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 SAIJ100AX90-50S FAQ
At 0.7 MPa the push force increases to 5497 N.
The rear adjuster screw lets you shorten the nominal 90 mm stroke by up to 50 mm, creating a usable travel window of 40 to 90 mm to fine-tune the end position.
