About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75
The AirTAC SAIJ32X170-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 95 to 170 mm, allowing you to dial back the nominal 170 mm stroke by up to 75 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks.
This variant features a SUS304 stainless steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for standard switches. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75 Is Used
Machine Changeover
Dial in the 95 to 170 mm travel window during product size transitions without physically replacing the cylinder.
Variable End Stops
Fine-tune the retract position at commissioning using the rear adjuster to perfect the mechanical stop point.
Light-Duty Positioning
Leverage the 402 N push force for precise, lighter-duty handling tasks requiring exact end-position calibration.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75 the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-stop tuning without adding external stops or swapping cylinders. If you need higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if your force requirements are lower, a smaller bore might be more efficient.
Because the nominal stroke is 170 mm, an external guide is not strictly mandated for side loads, though the 12 mm rod handles standard lateral stress well. For position holding without continuous air pressure, consider the SAIL or BSAI series, as this SAIJ adjuster is only a travel stop. It matches ISO 15552 mounting dimensions and uses a subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX170-75 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster allows you to mechanically shorten the effective stroke from 170 mm down to as little as 95 mm. It functions as a travel stop for end-position tuning and does not lock or hold the load without live air pressure.
