About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-20
The AirTAC SAIJ100X375-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 355 to 375 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This unit uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features a PT tapered G1/2 port. The rear stopper screw allows fine end-position tuning at commissioning without swapping components. It supports speeds of 30-800 mm/s and uses variable air cushions at both ends to manage impact deceleration.

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 SAIJ100AX375-20 Is Used
Product Changeover Stops
Dial in the exact end position within the 355-375mm window when switching a packaging line to a new carton size, avoiding the need to physically swap cylinders.
Machine Setup Tuning
Fine-tune the retract end position during initial commissioning to perfect a multi-stage assembly process without machining new external stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-20 the Right Cylinder?
If a project requires less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, whereas moving up to 125mm provides 6136N. Because the nominal stroke is 375mm, an external guide rail is recommended to prevent excessive side-loading on the rod.
The rear mechanism acts purely as a travel stop and does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 100mm bore, 375mm stroke, 20mm adjustment, PT G1/2 port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting footprint.
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 SAIJ100AX375-20 FAQ
An external adjusting screw at the rear of the cylinder acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 355 to 375 mm, enabling fine end-position tuning without changing the cylinder.
At the maximum operating pressure of 1.0 MPa, this 100mm bore cylinder generates a maximum push force of 801 kgf.
