About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50
The AirTAC SAIJ32X175-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 125-175 mm usable travel window by allowing you to trim the 175 mm nominal stroke back by up to 50 mm. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. Unlike fixed-stroke SAI units, this model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50 Is Used
Machine Setup Calibration
Dial in the exact end-of-stroke position during commissioning. The 50 mm adjustment window lets you fine-tune the 175 mm travel to perfectly match a new fixture without machining new spacers.
Product Size Changeover
Adapt a packaging line to different carton lengths quickly. Shorten the cylinder stroke from 175 mm down to 125 mm on the fly to accommodate varying product sizes without changing the actuator.
Light-Force Positioning
Leverage the 402 N push force at 0.5 MPa for precise low-force assembly tasks. The SUS304 stainless rod ensures reliable operation even in environments with potential moisture exposure.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50 the Right Cylinder?
Select this 32 mm bore model when you need variable end-stops for product changeovers, stepping down from a 40 mm bore (628 N push at 0.5 MPa) if your application requires less than 600 N of force. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. To replace an ISO 15552 cylinder, match the 32 mm bore, 175 mm stroke, 50 mm adjustment, PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Because the 175 mm stroke is relatively short for this bore, side-loading is minimal, though external guides are always recommended for optimal cylinder longevity.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX175-50 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 50 mm. This creates a usable travel window of 125 to 175 mm, allowing you to fine-tune the retract end position at commissioning without swapping cylinders.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf of push force.
