About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-10S
The AirTAC SAIJ100X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75 to 85 mm. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors for precise position detection.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads (G1/2). The rear adjustment screw allows you to fine-tune the end position at commissioning without adding external stops. Remember that this adjuster acts strictly as a travel stop, not a lock, so live air is required to hold the load.

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 SAIJ100AX85-10S Is Used
Machine Setup & Changeover
Dial in the exact 75-85 mm end-position during product line changeovers without physically replacing the cylinder or bolting on external stoppers.
End-Position Tuning
Fine-tune the retract end position by up to 10 mm during commissioning to perfect the seating of heavy 100 mm bore assemblies.
Variable End Stops
Adapt the stroke window dynamically on the factory floor for equipment that processes multiple part sizes requiring slightly different retraction points.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-10S the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider a SAIL or BSAI cylinder instead. To match this exact configuration, specify bore 100, stroke 85, 10 mm adjustment, PT ports, 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 SAIJ100AX85-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 85 mm nominal stroke by up to 10 mm, creating a 75 to 85 mm usable travel window. It is a stop only, not a lock, and cannot hold the load without live air pressure.
