About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-75S
The AirTAC SAIJ80X230-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated magnet (-S) enables direct mounting of CMSE reed and DMSE electronic solid-state sensors along the dual-side extruded barrel grooves.
By turning the external rear stopper screw, you can shorten the effective travel by up to 75mm, creating a usable 155-230mm positioning window. This allows precise end-position tuning at commissioning or during product changeovers without physically swapping the cylinder or adding external stops. The adjuster acts purely as a travel stop and works alongside the 36mm variable air cushions at both ends to decelerate the load; it does not hold the load without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX230-75S Is Used
Product Changeover
Dial in the exact end-stop between 155 and 230mm when switching product sizes on a packaging line, avoiding the need to physically swap out the actuator.
Machine Setup
Fine-tune the retract position during initial commissioning to perfectly align tooling, using the rear screw rather than adding external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-75S the Right Cylinder?
The 230mm stroke with a 75mm adjustment range is ideal for machines requiring variable end-stops between 155 and 230mm. For holding loads safely without continuous air pressure, this cylinder is not a lock; you should select an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead. To match this ISO 15552 interchangeable unit, specify: 80mm bore, 230mm stroke, 75mm adjust, PT tapered G3/8 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
Because the 230mm stroke approaches the mid-range of standard travel, ensure adequate external guidance to prevent side-loading on the 25mm rod, as long unsupported strokes can induce 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 SAIJ80 Adjustable Cylinder SAIJ80BX230-75S FAQ
The rear adjuster screw lets you trim the nominal 230mm stroke back by up to 75mm, providing a usable travel window of 155-230mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
