About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75S
The AirTAC SAIJ32X175-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 175mm nominal stroke that can be fine-tuned down by up to 75mm, creating a precise 100-175mm usable travel window. This wide adjustment band is perfect for machines requiring rapid product changeovers without swapping hardware.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) for position sensing. It operates at 30-800mm/s and uses a PT G1/8 port. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load. For position holding without pressure, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75S Is Used
Machine Changeover
Dial in the 100-175mm retract position during product size changes without adding external stopper blocks.
End-Position Tuning
Fine-tune the final retract point at commissioning to perfect sensor triggering and mechanical alignment.
Variable End Stops
Use the 75mm adjustment range to accommodate multiple part sizes on a single fixture line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75S the Right Cylinder?
Choose this 32mm bore when your application requires 402N push or 345N pull force at 0.5 MPa with highly variable end-stop requirements. If your setup needs less force, stepping down is not an option in this size range, but stepping up to a 40mm bore yields 628N push force. The adjustable stroke is selected over a fixed SAI cylinder when you need commissioning flexibility to dial in the exact retract position on the fly.
To replace an ISO 15552 cylinder, match the 32mm bore, 175mm stroke, 75mm adjustment range, PT G1/8 port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 175mm stroke is under 300mm, side-load stress is manageable, but always guide the load to protect the 12mm rod. The -S magnet works with AirTAC CMSE reed and DMSE electronic sensors.
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 SAIJ32BX175-75S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you shorten the 175mm nominal stroke by up to 75mm, providing a usable travel window of 100-175mm. It functions as a mechanical stop to set the end position, not as a lock.
