Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-100
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-100
The AirTAC SAIJ32X170-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 170 mm travel by up to 100 mm. This creates a wide 70-170 mm usable window, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops. 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.
Built with a SUS304 stainless steel rod (option B) for corrosion resistance, this model uses a PT tapered G1/8 port and operates at speeds between 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop for deceleration and end-position setting; it does not hold the load without live air pressure, so a SAIL or BSAI lock is required for fail-safe positioning.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-100 Is Used
Machine Changeovers
Rapidly reconfigure the 70-170 mm travel window during product size transitions on a conveyor line without physically swapping the actuator.
End-Stop Tuning
Fine-tune the exact retract position at commissioning to align tooling perfectly, using the rear screw rather than adding external stopper blocks.
Variable Positioning
Accommodate multiple package sizes on a single handling station by dialing the stroke back from 170 mm down to 70 mm as needed.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-100 the Right Cylinder?
Choose this 32 mm bore when your application requires a 70-170 mm stroke range and a moderate 402 N output at 0.5 MPa. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force. The wide 100 mm adjustment range is ideal for product-size changeovers on a packaging line, allowing operators to set new end stops quickly rather than replacing the entire cylinder.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets (omitting FB, CA, CB, and CR). Because the 170 mm stroke is under 300 mm, side-load stress is minimal, though the 12 mm rod and M10x1.25 thread still require an external guide for heavy radial 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 SAIJ32BX170-100 FAQ
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 170 mm down to 70 mm. This creates a 100 mm adjustable window for fine-tuning the retract end position during setup or product changeovers.
At a 0.5 MPa operating pressure, the SAIJ32X170-100 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.
