About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-75
The AirTAC SAIJ100X800-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end-of-travel position without swapping out the unit. It provides a usable travel window of 725-800mm, letting you dial back the 800mm nominal stroke by up to 75mm during commissioning or product changeovers.
This model features a SUS304 stainless steel rod for superior corrosion resistance and carries a 25mm rod diameter with an M20x1.5 thread, which handles substantial side loads despite the long stroke. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It uses a PT G1/2 port and relies on a 36mm air cushion at both ends to decelerate the load smoothly.

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 SAIJ100BX800-75 Is Used
Variable Product Changeover
Dial in the exact 725 to 800mm push distance on packaging lines when box sizes change, avoiding the need to physically swap cylinders or re-engineer external hard stops.
Long-Stroke Material Handling
Actuate large gates or diverters over an 800mm travel path, using the rear screw to trim the final resting position by up to 75mm for perfect alignment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-75 the Right Cylinder?
Choose this 100mm bore actuator when your application requires substantial thrust, such as pushing 3927N at a standard 0.5 MPa, and you need the flexibility to adjust end positions on the fly rather than relying on a fixed-stroke SAI cylinder. If your process needs less force and a shorter setup, stepping down to an 80mm bore yields 2513N at 0.5 MPa. Conversely, moving up to a 125mm bore provides 6136N at 0.5 MPa for heavier loads.
Because the 800mm stroke is quite long, always use an external guide to support the load and prevent rod bending, as the rear adjuster and air cushion act only as travel stops—they do not hold the load without live air pressure. For true load-holding without continuous pressure, consider an external rod lock or the AirTAC SAIL or BSAI series. This SKU is dimensionally interchangeable with ISO 15552 cylinders, featuring a PT G1/2 port, a 75mm adjustment range, and mounting options limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX800-75 FAQ
At the maximum recommended pressure of 0.9 MPa, the push force increases to 7068N.
The rear adjusting screw acts as an external stopper that lets you shorten the effective travel from the nominal 800mm down to a minimum of 725mm. This allows precise end-position tuning at commissioning without adding external stops, though it does not lock the load without live air pressure.
