About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30S
The AirTAC SAIJ100X165-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 5497 N of push force at 0.7 MPa and provides a usable travel window of 135 to 165 mm, letting you trim the retract position by up to 30 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and ships with a magnet (-S) for position detection. It uses PT tapered ports and supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster functions purely as a travel stop to fine-tune deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30S Is Used
Product Changeovers
Dial in the 135-165 mm travel window during format size changes on packaging lines without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke by up to 30 mm at machine commissioning to achieve exact material feed positioning, absorbing mechanical tolerance variations.
Heavy Forming Operations
Leverage the 5497 N push force at 0.7 MPa for pressing or holding tasks where the final end-stop needs micro-adjustments to prevent workpiece damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, such as the 5497 N push force at 0.7 MPa, combined with variable end-stop positioning. If your setup needs less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa. The adjustable stroke is ideal for product-size changeovers on a line, preventing the need to swap out a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 100 mm bore, 165 mm stroke, PT ports, and the -S magnet requirement.
Because the nominal stroke is 165 mm, side-loading is less of a concern than with longer strokes, but the 25 mm rod and M20x1.5 thread still require external guiding for heavy lateral loads. Remember that the rear adjuster only sets the travel end; for load-holding without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the standard air cushion.
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 SAIJ100AX165-30S FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder provides 5497 N of push force and 4523 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 165 mm down to 135 mm. It sets the travel end and deceleration point but does not lock the load without continuous air pressure.
