About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-50S
The AirTAC SAIJ100X55-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a 55 mm nominal stroke and a 50 mm adjustment range, it provides a highly versatile 5-55 mm usable travel window for precise product changeovers.
This variant includes an SUS420J2 stainless steel rod for improved corrosion resistance and a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid is supplied via a PT G1/2 tapered port. It supports a standard mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX55-50S Is Used
Product Changeover
Quickly adjust the 5-55 mm travel window to accommodate different package sizes on the same line without swapping hardware.
Machine Setup
Fine-tune the retract end-position during commissioning to achieve exact clamping or pressing depths on heavy machinery.
Variable End Stops
Use the 50 mm adjustment screw to modify the stroke limit dynamically for flexible manufacturing processes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-50S the Right Cylinder?
The 50 mm adjuster is ideal for dialing in exact end stops during commissioning without adding external stops. For position holding without live air, note that this rear adjuster acts only as a travel stop, not a lock; you would need an external rod lock or a SAIL cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 55 mm stroke, 50 mm adjustment, PT G1/2 port, and -S magnet. Because the stroke is relatively short at 55 mm, side-loading is less severe than on long strokes, but the 25 mm rod and M20x1.5 thread still handle robust loads. Operating speed ranges from 30-800 mm/s.
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 SAIJ100AX55-50S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to trim the 55 mm nominal stroke back by up to 50 mm, creating a 5-55 mm usable travel window. It acts as a mechanical stop to set the end position and is not a lock.
