About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-30
The AirTAC SAIJ80X175-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 175 mm stroke that can be dialed back by up to 30 mm, creating a precise 145-175 mm usable travel window for fine-tuning end positions at commissioning. Delivering 2513 N of pull force at 0.5 MPa, it handles substantial loads while maintaining a standard 30-800 mm/s speed range.
This model uses a robust 25 mm carbon steel rod with an M20x1.5 thread, paired with PT (tapered) port threading and a 36 mm air cushion at both ends to manage kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Mounting options cover the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-30 Is Used
Machine Changeover
Dial in the 145-175 mm travel window during product size transitions without swapping cylinders or bolting on external stops.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning to perfect part ejection or clamping accuracy.
Variable Diverter Stops
Adjust the stroke length on the fly to handle different package sizes on a sorting line without changing the actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-30 the Right Cylinder?
Choose this 80 mm bore when your application requires more force than a 63 mm bore (which provides 1402 N pull at 0.5 MPa) but does not need the full 3681 N pull of a 100 mm bore. The 30 mm adjustment range is ideal for product-size changeovers, allowing you to shift the retract end-position without swapping the cylinder or adding external mechanical stops. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ80X175-30 will not hold a load without live air pressure. For true load-holding, consider an external pilot-operated check valve or the related BSAI clamp-lock series. To match this ISO 15552 replacement exactly, specify an 80 mm bore, 175 mm stroke, 30 mm adjuster, PT port thread, and no magnet.

- ✓ 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 SAIJ80X175-30 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 30 mm. This provides a usable travel window of 145 to 175 mm, allowing you to fine-tune the end position at commissioning without altering the cylinder's standard ISO 15552 mounting footprint.
At a standard 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N of push force at the maximum 0.9 MPa pressure.
