About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-10
The AirTAC SAIJ100X85-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 75 to 85 mm, allowing you to dial back the nominal 85 mm stroke by up to 10 mm during commissioning without adding external stops.
This unit is built with a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads for its G1/2 connections. It supports standard AirTAC CMSE and DMSE sensors via dual-side barrel grooves, and its mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ100AX85-10 Is Used
Machine Changeover
Dial in the exact 75 to 85 mm end-position during product size changes without swapping out the entire cylinder assembly.
End-Stop Tuning
Fine-tune the retract stroke by up to 10 mm at commissioning to perfect machine timing and eliminate hard mechanical crashes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-10 the Right Cylinder?
An adjustable-stroke SAIJ is selected over a fixed SAI when a machine requires variable end-stops for product changeovers or fine end-position tuning. Note that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its load without live air, so consider an SAIL or BSAI cylinder if true load-holding is required.
For any application using a stroke of 300 mm or more, always factor in an external guide to support the rod and prevent excessive side-loading. To match this ISO 15552 cylinder, specify the 100 mm bore, 85 mm stroke, 10 mm adjustment, PT port threads, and your required mounting interface.
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 SAIJ100AX85-10 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 85 mm down to 75 mm, creating a 75-85 mm adjustable window. This allows precise end-position tuning at commissioning without replacing the cylinder.
