About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-50
It features a 50mm adjustment range that creates a usable travel window of 35 to 85mm, allowing you to dial in the exact retract end-position during commissioning without swapping out the actuator. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting.
This configuration utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered port threads. The 25mm rod diameter and M20x1.5 rod thread provide a robust interface capable of handling substantial side loads, while the adjustable air cushions at both ends manage deceleration across its 30-800mm/s speed range.

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 SAIJ100AX85-50 Is Used
Variable End-Stop Forming
Dial in the retract position by up to 50mm to accommodate different material thicknesses or bending depths without changing the cylinder setup.
Product Changeover Diverters
Quickly reconfigure a sorting gate or end-stop on a packaging line by adjusting the stroke window from 85mm down to 35mm for varying carton sizes.
Commissioning Fine-Tuning
Eliminate mechanical shimming during machine setup by using the rear screw to precisely set the 100mm bore's final resting position under load.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-50 the Right Cylinder?
Choose this 100mm bore actuator when an application demands high thrust combined with variable end-stops, such as accommodating multiple product sizes on a single line. The integrated rear adjuster acts purely as a mechanical stop for position tuning and does not hold the load without live air pressure. For true load-holding in the event of air loss, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100mm bore, 85mm nominal stroke, 50mm adjustment code, PT port thread, and your required mounting hardware. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the nominal stroke is under 300mm, external guide rails are less critical here than on longer strokes, but the load should still remain within the rod's bearing capacity.
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 SAIJ100AX85-50 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 801kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 85mm nominal length down to 35mm, creating a 35-85mm usable travel window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
