About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40S
The AirTAC SAIJ100X110-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 110 mm travel to a precise usable window of 70-110 mm. Delivering a robust 3927 N push force at 0.5 MPa, it handles heavy loads while featuring a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance.
This model includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors mounted in the dual-side extruded barrel grooves. The rear stopper acts purely as a travel end-position tuner for product changeovers, not a load-holding lock; for dead-air positioning, an external SAIL or BSAI locking cylinder is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40S Is Used
Product Changeover Tuning
Quickly dial in the 70-110 mm stroke window during format changes on a packaging line, using the rear adjuster to set exact end positions for different carton sizes.
Heavy Pressing Operations
Leverage the 3927 N push force at 0.5 MPa for pressing bearings or forming components, relying on the fine-tuned stopper to prevent over-travel.
Automated End-Stopping
Use as an adjustable hard stop in automated assembly stations where the exact retraction point varies between product runs and needs on-the-fly calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40S the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm variant gives you a significant thrust upgrade, stepping up from 2513 N to 3927 N at 0.5 MPa. The 40 mm adjustment range is ideal when a machine processes varying part sizes, letting you fine-tune the end stop during commissioning without adding external physical stops or swapping out the entire cylinder.
When matching your ISO 15552 interchangeable footprint, confirm the PT tapered port threads, the 110 mm nominal stroke, the 40 mm adjuster code, and the -S magnet requirement. Because the nominal stroke of 110 mm is relatively short for this bore, side-load stress is minimal, but always ensure the M20x1.5 rod thread is aligned to prevent binding during retraction.
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 SAIJ100AX110-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At a higher 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 70-110 mm from the nominal 110 mm stroke, enabling precise end-position tuning without changing the cylinder.
