About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-50
The AirTAC SAIJ100X90-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 90 mm nominal travel to create a precise 40-90 mm usable window.
Because the adjuster acts purely as a mechanical stop on the retract end, it decelerates the load but cannot hold position without live air pressure. For load-holding requirements, an external rod lock or related types like SAIL or BSAI are required. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX90-50 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 40-90 mm window during commissioning to accommodate different product lengths without changing the cylinder.
Production Line Changeover
Quickly reset the stroke stop for new packaging sizes or tooling profiles, reducing machine downtime between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-50 the Right Cylinder?
An adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops for product changeovers, letting you fine-tune the travel without swapping hardware.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 50 mm adjustment, PT ports, and mounting style. Note that the -S magnet option is not specified here, so position sensing via CMSE or DMSE switches is not available without it. The 25 mm rod and M20x1.5 thread handle high side loads, though long unsupported strokes still need an external guide.
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 SAIJ100AX90-50 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 50 mm, creating a usable travel window of 40-90 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
