About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-40S
The AirTAC SAIJ100X170-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 5497N push force at 0.7MPa, while the integrated -S magnet enables position feedback via AirTAC CMSE reed and DMSE electronic sensors.
This specific SKU provides a 130-170mm usable travel window, allowing you to fine-tune the retract end-position by up to 40mm directly at the machine without swapping hardware. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-40S Is Used
Variable End-Stop Setup
Dial in the exact retract position within the 130-170mm window during machine commissioning without adding external stopper blocks.
Product Size Changeover
Quickly adapt the stroke length on packaging lines when switching to a different product size, using the 40mm adjustment range.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable high-force motion in washdown or chemically exposed manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-40S the Right Cylinder?
Select this 100mm bore cylinder when your application requires substantial thrust—stepping down to an 80mm bore drops the 0.5MPa push force to 2513N. Choose this adjustable SAIJ variant over a fixed-stroke SAI when you need precise end-stop tuning during commissioning or frequent product changeovers. The rear adjuster acts purely as a travel stop to set the end position; it does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series.
When ordering, confirm the 100mm bore, 170mm stroke, 40mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300mm, side-load concerns are minimal, but the substantial 25mm rod and M20x1.5 thread provide excellent rigidity if external guides are added.
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 SAIJ100 Adjustable Cylinder SAIJ100BX170-40S FAQ
At 0.5MPa it provides 3927N push and 3681N pull. At 0.7MPa the push force increases to 5497N, with a maximum rated force of 801kgf at 1.0MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 170mm down to 130mm, giving a 130-170mm usable window. It functions as a mechanical stop and does not lock the load without air pressure.
