About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-50S
The AirTAC SAIJ100X800-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 100mm bore and an 800mm nominal stroke that can be fine-tuned down by up to 50mm, yielding a precise 750-800mm usable travel window.
This variant includes a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and is equipped with a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The 25mm rod diameter and M20x1.5 thread provide robust resistance to side loads, while the extruded aluminum barrel integrates sensor grooves on both sides. The rear adjusting screw acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

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 SAIJ100AX800-50S Is Used
Variable End-Stop Tuning
Dial in the exact 750-800mm retraction point during machine commissioning to accommodate different product sizes without installing external physical stops.
Changeover Optimization
Quickly adapt automated machinery to new production runs by turning the rear screw, reducing downtime associated with repositioning fixed-stroke SAI cylinders.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-50S the Right Cylinder?
Choose this adjustable-stroke model when a machine setup requires variable end stops or fine-tuning during commissioning without physically swapping cylinders or adding external stops. Because the 800mm stroke is relatively long, an external guide is recommended to prevent rod sag and excessive side loading.
For load-holding without continuous air pressure, note that the rear adjuster and air cushions function only as stops and deceleration devices, not as a lock. You would need an external rod lock, a pilot-operated check valve, or an AirTAC SAIL/BSAI cylinder for secure load holding. To match this exact configuration for an ISO 15552 replacement, specify: 100mm bore, 800mm stroke, 50mm adjustment, PT tapered ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S 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 SAIJ100AX800-50S FAQ
The operating speed range is 30-800 mm/s, and it uses G1/2 ports with a 36mm cushion.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 50mm from the 800mm nominal stroke, giving a 750-800mm usable window. It only sets the end position; it does not lock or hold the load without live air pressure.
