About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-40
The AirTAC SAIJ80X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down by up to 40 mm. This yields a usable end-position window of 135 to 175 mm, letting you dial in the retract stop precisely during commissioning or product changeover without adding external stops.
This 80 mm bore model uses G3/8 ports and includes variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE solid-state switches, though this specific SKU is supplied without a magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some other variants.

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 SAIJ80X175-40 Is Used
Product Changeover Dials
Quickly fine-tune the 135-175 mm retract position when switching a packaging line to a different carton size, eliminating the need to swap out the entire actuator.
End-Stop Calibration
Nail the exact end-of-stroke position during machine commissioning by turning the rear screw, avoiding the hassle of machining external stop blocks.
Variable Diverter Stroke
Adjust the physical travel limit on a conveyor sorting arm to handle varying package lengths on the fly without reprogramming the machine controller.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-40 the Right Cylinder?
The adjustable-stroke feature is ideal when machine setups require variable end-stops for different product sizes, whereas a fixed SAI cylinder would lock you into a single 175 mm travel. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. To replace an ISO 15552 unit, match the 80 mm bore, 175 mm stroke, 40 mm adjustment range, G3/8 PT ports, and the required mounting interface.
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 SAIJ80X175-40 FAQ
A rear adjuster screw lets you shorten the nominal 175 mm stroke by up to 40 mm, providing a usable travel window of 135 to 175 mm. This stopper sets the retract end position but does not lock the load without continuous air pressure.
At 0.7 MPa, the push force increases to 3518 N.
