About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-50S
The AirTAC SAIJ80X175-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 175 mm nominal stroke that can be dialed back by up to 50 mm, providing a usable travel window of 125-175 mm for precise end-position tuning during commissioning.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to set the retract end, meaning it cannot hold a 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 SAIJ80BX175-50S Is Used
Product Changeovers
Dial in the 125-175 mm travel window during format size changes on a packaging line without swapping hardware.
Machine Setup
Fine-tune the retract end-position at commissioning to perfectly seat parts using the 50 mm rear stopper.
Variable End Stops
Adjust the effective stroke dynamically for testing different material thicknesses in a clamping fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-50S the Right Cylinder?
The 50 mm adjustment range is ideal for machines requiring variable end stops or frequent product-size changeovers, preventing the need to physically swap cylinders or bolt on external stops. For any load-holding requirements without continuous live air, this adjustable stop is insufficient; you must integrate an external rod lock or look at the SAIL or BSAI series.
To match this exact ISO 15552 replacement, confirm the 80 mm bore, 175 mm stroke, 50 mm adjustment range, PT G3/8 port, and the -S magnet option. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since this model has a 175 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread handle side loads well, but any significantly long unsupported stroke still necessitates an external guide to prevent binding.
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 SAIJ80BX175-50S FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that shortens the 175 mm nominal stroke by up to 50 mm, creating a 125-175 mm usable travel window. It functions as a stop and does not lock the load without live air.
