About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-75
The AirTAC SAIJ100X850-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 775-850mm usable travel window, allowing you to dial back the 850mm nominal stroke by up to 75mm during commissioning.
This model features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. The rear adjuster acts as a mechanical stop to fine-tune the end position without adding external stops. It is not a locking device, so live air pressure is required to hold the load. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX850-75 Is Used
Variable End-Stop Forming
Dial in the exact 775 to 850mm travel window for pressing or forming operations, accommodating different material thicknesses without changing the cylinder.
Machine Changeover
Quickly fine-tune the rear stop position during product size changeovers on a production line, saving time on mechanical reconfiguration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-75 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust (5497N at 0.7 MPa) and on-the-fly end-position tuning. If you need less force, the 80mm bore offers 3518N at 0.7 MPa. If your setup requires true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is strictly a travel stop.
When replacing an ISO 15552 cylinder, match the 100mm bore, 850mm stroke, 75mm adjustment range, PT G1/2 port, and the desired mounting accessory. Because the 850mm stroke is long, an external guide is recommended to prevent excessive side-loading on the rod.
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 SAIJ100AX850-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75mm. This creates a usable travel window of 775 to 850mm, allowing you to fine-tune the end position at commissioning without swapping the cylinder.
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf of push force.
