About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50S
The AirTAC SAIJ32X175-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 125-175 mm usable travel window, allowing you to trim the 175 mm nominal stroke by up to 50 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-position detection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50S Is Used
Product Changeover
Dial in the 125-175 mm travel window on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise alignment without adding external mechanical stops.
Variable End Stops
Use the 50 mm adjustment range to alter the stroke endpoint dynamically for testing actuator limits in prototype assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-50S the Right Cylinder?
Select this 32 mm bore when an application requires exact end-position tuning without swapping components; if you need substantially more force, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. The rear adjuster acts purely as a mechanical stop to set the retract position and decelerate the load alongside the air cushion. It does not hold the load without live air pressure, so for fail-safe load holding you should consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders. To match this ISO 15552 interchangeable cylinder exactly, specify: 32 mm bore, 175 mm stroke, 50 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet. Because the stroke is under 300 mm, side-load stress on the 12 mm rod is manageable, though external guiding remains recommended for heavy off-center loads.
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 Adjustable Cylinder SAIJ32 SAIJ32BX175-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 175 mm nominal stroke by up to 50 mm, creating a 125-175 mm usable travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
