About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-30
The AirTAC SAIJ80X160-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 130 to 160 mm, allowing you to dial back the nominal 160 mm stroke by up to 30 mm during commissioning.
This unit is built with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and deceleration; it does not lock 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 SAIJ80AX160-30 Is Used
Machine Changeover
Quickly fine-tune the extend end-position by up to 30 mm when switching a packaging line to a different product size, avoiding mechanical cylinder swaps.
Variable End-Stops
Dial in the exact clamping travel between 130 and 160 mm during initial commissioning to accommodate varying workpiece heights without adding external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-30 the Right Cylinder?
The 30 mm adjustment range is ideal for applications requiring variable end-stops or product-size changeovers, eliminating the need to swap cylinders or bolt on external stops. For load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is only a travel stop.
This model uses a G3/8 port and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552. Because the 160 mm stroke is below the 300 mm threshold, external side-load guides are less critical here, though the robust 25 mm rod and M20x1.5 thread handle standard operational stresses effectively.
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 SAIJ80AX160-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you mechanically shorten the effective stroke from 160 mm down to 130 mm. This creates a 30 mm tuning window for setting precise end-positions at commissioning, but the adjuster functions only as a travel stop and does not hold the load without live air.
