About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20S
The AirTAC SAIJ80X230-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5MPa and features a built-in magnet for position sensing. By turning the rear screw, you can trim the effective travel within a 210-230mm window, providing precise end-position tuning without swapping out the entire actuator.
This 80mm bore actuator uses a G3/8 PT port and a 25mm carbon steel rod to handle high side loads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic switches exactly where needed for your automation cycle.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20S Is Used
Machine Changeover
Dial in the 210-230mm travel window during product size changes to set new retraction endpoints without changing the cylinder.
End-Position Tuning
Fine-tune the retraction stop at commissioning to avoid mechanical crashes, using the rear screw rather than external shims.
Heavy Assembly Pressing
Leverage the 2513N push force at 0.5MPa for pressing heavy components while adjusting the stroke to accommodate various part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20S the Right Cylinder?
Choose this 80mm bore when an application requires substantial thrust, stepping up from a 63mm bore that provides 1559N at 0.5MPa. The 20mm adjustment range is ideal for fine-tuning the retraction point during commissioning or product changeover, preventing the need to bolt on external stops. For a fixed end position, a standard SAI cylinder would suffice, but the SAIJ variant grants setup flexibility.
When replacing an ISO 15552 cylinder, match the 80mm bore, 230mm stroke, 20mm adjustment, PT port thread, and -S magnet requirement. Because the 230mm stroke exceeds 300mm no external guide is strictly mandated, yet the 25mm rod thread handles significant side loads. Remember that the rear adjuster is a travel stop, not a lock; to hold a load without live air, use an external rod lock or a SAIL cylinder.
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 SAIJ80X230-20S FAQ
At 0.5MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.7MPa.
The rear adjuster acts as a mechanical stop that shortens the nominal 230mm stroke by up to 20mm, creating a 210-230mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
