About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-100
The AirTAC SAIJ100X650-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel features sensor grooves on both sides, though this specific configuration omits the internal magnet, meaning position sensing via CMSE reed or DMSE electronic switches is not enabled out of the box.
This unit utilizes a SUS420J2 stainless steel rod (material code A) with an M20x1.5 thread and PT-tapered G1/2 ports. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping cylinders, and it works in tandem with 36 mm variable air cushions at both ends to decelerate the load. Note that neither the adjuster nor the cushion holds the load without live air pressure; for true position holding, consider the SAIL or BSAI series instead.

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 SAIJ100AX650-100 Is Used
Product Changeover
Dial in the exact end-position from 550 to 650 mm during production line changeovers without physically replacing the cylinder or adding external mechanical stops.
Machine Setup Tuning
Fine-tune the rear mechanical stopper at commissioning to perfect the stroke length, compensating for mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-100 the Right Cylinder?
An adjustable stroke is ideal for product changeover lines where the exact end-position needs frequent fine-tuning without adding external stops. When matching an ISO 15552 replacement, verify the 650 mm stroke, 100 mm adjustment range, PT G1/2 port, and the absence of the -S magnet option. Because the stroke is 650 mm, the long unsupported piston rod is susceptible to side-loading; always use an external guide to prevent premature wear.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR brackets found in other series. The operating speed for this bore is 30-500 mm/s, making it suitable for moderately paced, high-force applications.
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 SAIJ100AX650-100 FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke by up to 100 mm, providing a usable travel window of 550 to 650 mm. It acts as a travel stop and does not lock the load without live air pressure.
At the maximum 1.0 MPa operating pressure, it can deliver up to 801 kgf.
