About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-75
The AirTAC SAIJ100X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the end-of-travel position. It provides a usable travel window of 725-800 mm, giving you 75 mm of flexibility to dial in the exact retract distance without swapping out the physical cylinder. In the 100 mm bore class, it delivers substantial thrust, pushing with 7068 N and pulling with 3681 N at 0.9 MPa.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced resistance to corrosion and surface wear. It uses a PT G1/2 port thread and relies on a 36 mm variable air cushion at both ends to decelerate the load. As an extruded aluminum profile cylinder, it includes sensor grooves on both sides; without the -S magnet option, it is not equipped for position sensing.

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 SAIJ100AX800-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 725 to 800 mm during machine commissioning to accommodate different material lengths without installing external stopper blocks.
Product Size Changeover
Quickly adapt a long-stroke actuation station to new product families by adjusting the rear stopper screw, reducing downtime between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-75 the Right Cylinder?
The 75 mm rear adjustment screw is ideal for product changeovers on a line, letting you set a new retract stop on the fly instead of adding external mechanical stops. Remember that the adjuster and the air cushions only decelerate the load; they do not hold it without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 800 mm stroke, 75 mm adjustment range, PT G1/2 port, and the required mounting accessory. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 800 mm stroke is long, the 25 mm rod will experience amplified side-loading moments; always guide the load externally to prevent rod binding and premature seal wear.
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 SAIJ100AX800-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm. This creates a 725-800 mm usable travel window, allowing precise end-position tuning at commissioning without replacing the cylinder.
