About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-20
The AirTAC SAIJ32X170-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel, creating a 150-170 mm usable window for precise commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-20 Is Used
End-Stop Tuning
Dial in the exact 150-170 mm retract position during machine commissioning to perfect part ejection without machining new stopper blocks.
Product Changeover
Quickly adapt a packaging line for different carton sizes by turning the rear adjuster screw to shift the pneumatic stroke window.
Light-Load Routing
Use the 402 N push force to deflect or gate lightweight packages on a conveyor, with the flexibility to alter the travel distance later.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-20 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa; step up to a 40 mm bore if you need 628 N. The 20 mm adjustment range is ideal for fine-tuning the end-of-stroke position during machine setup or product changeover without swapping out the entire cylinder or adding external stopper blocks. For applications requiring position holding without live air, consider the SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting sets. It uses a G1/8 port, operates at 30-800 mm/s, and lacks a magnet for sensors. Since the 170 mm stroke is relatively short, side-load stress is minimal, but an external guide is still recommended for heavy offsets.
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 SAIJ32BX170-20 FAQ
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 deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 170 mm stroke by up to 20 mm, creating a 150-170 mm travel window. It requires live air to maintain position and does not lock the load.
