About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-20
The AirTAC SAIJ32X175-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 155-175 mm from the 175 mm nominal stroke. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This specific configuration includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning; it is not a locking mechanism and will not hold the load without live air pressure. For load-holding applications without continuous air supply, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-20 Is Used
Machine Changeover
Dial in the 155-175 mm travel window during product size transitions to perfectly position components without swapping the entire cylinder.
End-Position Tuning
Use the rear stopper screw to fine-tune the retract end position during initial commissioning, eliminating the need for external shims.
Light Assembly Clamping
Apply up to 402 N of push force for securing delicate parts during assembly, adjusting the stroke slightly to accommodate varying material thicknesses.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-20 the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient, stepping down from a 40 mm bore (which provides 628 N) to save space and air consumption. An adjustable stroke is highly beneficial over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise machine setup without adding external physical stops.
Because this model features a 175 mm stroke, the 12 mm rod and M10x1.25 thread handle moderate side loads, though long unsupported travels still require an external guide. It is dimensionally interchangeable with ISO 15552 cylinders and supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that without a magnet, this unit does not support CMSE or DMSE sensors.

- ✓ 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 SAIJ32AX175-20 FAQ
The nominal stroke is 175 mm, but the rear adjuster allows you to shorten the effective travel by up to 20 mm, providing a usable stroke window of 155 to 175 mm.
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
