About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-30
The AirTAC SAIJ100X800-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability simplifies commissioning and product changeovers without swapping the hardware.
This unit uses a SUS420J2 stainless steel rod (code A) for superior wear resistance and accepts PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches. Remember, the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live 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 SAIJ100AX800-30 Is Used
Variable End-Stop Machining
Dial in the 770-800mm travel window to accommodate varying part lengths on a machining line without repositioning the cylinder.
Product Changeover Setup
Quickly adjust the rear stopper by up to 30mm during packaging line format changes, saving time over swapping fixed cylinders.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-30 the Right Cylinder?
Choose this 100mm bore when your application requires more thrust than a 63mm bore (which provides 1559N at 0.5 MPa), but you want to avoid the bulk of a 125mm unit. The adjustable stroke is ideal for variable end-stops and machine setup, providing fine end-position tuning that a fixed-stroke SAI cylinder cannot offer. Because the stroke is 800mm, an external guide is highly recommended to prevent excessive side-loading on the rod.
For an exact ISO 15552 replacement, match the 100mm bore, 800mm stroke, 30mm adjustment, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This configuration omits the FB, CA, CB, and CR mounts. If you need true load-holding without live air, select the SAIL or BSAI series instead.
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 SAIJ100AX800-30 FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a stopper that trims the effective travel back from 800mm to a minimum of 770mm. It sets the end position but does not lock the load without air pressure.
