About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100
The AirTAC SAIJ100X170-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 170 mm stroke that can be dialed back by up to 100 mm, creating a precise 70-170 mm usable travel window for highly flexible positioning. Delivering 3927 N of push force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads.
The rear adjustment mechanism acts strictly as a mechanical stop to fine-tune the end position during commissioning or product changeovers without swapping the cylinder. It is not a locking device and will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100 Is Used
Dynamic Product Changeover
Quickly reposition the end-stop via the rear screw when switching between product lengths on a packaging line, utilizing the 70-170 mm travel window.
Precision Pressing Setup
Fine-tune the exact extension point during machine commissioning to ensure perfect pressing force without machining custom external stoppers.
Adjustable Ejection Station
Eject varying part sizes from a machining center by dialing in the exact stroke needed for each run, saving setup time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-100 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust (3927 N push at 0.5 MPa) alongside extreme setup flexibility. The massive 100 mm adjustment range is perfect for prototyping cells or lines handling varying product sizes, allowing you to shift the end-stop dynamically rather than bolting on external stops. If your force needs are lower, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa, while moving up to a 125 mm bore provides 6136 N.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, PT port threads, and the specific 100 mm adjustment code. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 170 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but always ensure adequate guiding for the 25 mm rod diameter in heavier setups.
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 SAIJ100AX170-100 FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 70 to 170 mm, letting you set the exact end position without adding external stops.
At a 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
