About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-50S
The AirTAC SAIJ100X50-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This wide adjustment range allows you to dial in the exact end position during commissioning without adding external stops. Equipped with a SUS420J2 stainless steel rod (option A) and a PT tapered port, it handles demanding environments.
The integrated magnet (-S) supports CMSE reed and DMSE solid-state sensors for precise position feedback. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load. For position holding without pressure, consider the SAIL or BSAI series.

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 SAIJ100AX50-50S Is Used
Machine Setup & Changeover
Fine-tune the 0-50mm travel window during product size changes without physically replacing the actuator or bolting on external stops.
Variable End-Stop Positioning
Dial in the exact retraction point at commissioning using the rear screw, allowing precise control over clamping or pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-50S the Right Cylinder?
If your application requires less force, stepping down to an 80mm bore yields 2513N, whereas moving up to a 125mm bore offers 6136N. The adjustable stroke is ideal for product changeovers on a line, letting you vary the end-stop by up to 50mm instead of swapping a fixed-stroke SAI cylinder.
When matching an ISO 15552 replacement, verify the 50mm stroke, 0-50mm adjustment, PT G1/2 port, and the -S magnet. The 25mm rod and M20x1.5 thread handle high side loads, but for any stroke over 300mm, an external guide is mandatory. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX50-50S FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster allows you to trim the effective travel anywhere within a 0 to 50mm window. It acts as a mechanical stop to fine-tune the end position, but it is not a lock, so live air pressure is required to hold the load.
