About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-75
The AirTAC SAIJ100X475-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, pushing with 7068N at 0.9 MPa and pulling 3681N at 0.5 MPa. The integrated adjuster allows you to trim the 475mm nominal stroke back by up to 75mm, creating a precise 400-475mm usable travel window for exact end-position tuning during commissioning.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks a magnet for electronic position sensing. The rear adjuster acts strictly as a mechanical stop to set the travel end; it does not lock or hold the load without continuous 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 SAIJ100AX475-75 Is Used
Product Changeover Dials
Adjust the 400-475mm travel window on the fly to accommodate different package lengths on a packaging line without replacing the actuator.
Machine Setup Fine-Tuning
Use the rear stopper to precisely set the retracted end position during initial commissioning, avoiding the need for custom machined spacers.
Variable End-Stop Forming
Dial in the exact stroke distance required for pressing or forming operations where material thickness variations demand a flexible travel limit.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-75 the Right Cylinder?
The 75mm adjustment range is chosen over a fixed-stroke SAI when a machine handles multiple product sizes, allowing operators to dial in the end-stop during changeover without swapping the cylinder or adding external stops. Because the 475mm stroke is substantial, an external guide is recommended to prevent rod side-loading and premature seal wear.
For an exact ISO 15552 replacement, match the 100mm bore, 475mm stroke, 75mm adjustment, PT G1/2 ports, SUS420J2 rod, and the absence of a magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If your application requires true load-holding without live air, this cylinder is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.

- ✓ 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 SAIJ100AX475-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 475mm nominal stroke by up to 75mm. This provides a usable travel window of 400-475mm. It only sets the end position and does not decelerate the load; the integrated air cushions handle shock absorption.
At 0.9 MPa operating pressure, the push force is 7068N, and at 0.5 MPa it is 3927N. The pull force at 0.5 MPa is 3681N. The maximum operating pressure is 1.0 MPa.
