About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-100S
The AirTAC SAIJ100X165-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down to a 65-165 mm window. Delivering 5497 N of push force at 0.7 MPa, it handles heavy positioning tasks with precision. This specific SKU includes a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors.
The generous 100 mm adjustment range is ideal for product changeovers, letting you dial in the exact end position without swapping out the cylinder or adding external stops. It uses a PT tapered G1/2 port and relies on variable air cushions at both ends to decelerate the load smoothly. Remember that the rear adjuster is a travel stop, not a lock; it will not hold the load if air pressure drops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-100S Is Used
Product Changeover
Dial in the 100 mm adjustment range to quickly switch end-stops for different package sizes on a packaging line without changing cylinders.
Machine Setup
Fine-tune the 65-165 mm travel window during commissioning to perfectly time the press motion against hard stops.
Assembly Stations
Leverage the 5497 N push force at 0.7 MPa to drive heavy components into place while using the rear screw to set the exact insertion depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-100S the Right Cylinder?
Choose this 100 mm bore when your application requires more thrust than a 63 mm bore provides (2182 N at 0.7 MPa) but you want to avoid the heavier framing and higher air consumption of a 160 mm bore (14074 N at 0.7 MPa). The 100 mm adjuster range is excellent for machines running multiple product sizes, as it allows fast end-position tuning at commissioning without external stopper hardware.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 165 mm stroke, G1/2 PT ports, and the -S magnet requirement. SAIJ uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). For any load-holding requirements without live air pressure, the SAIJ adjuster is insufficient; you must integrate an external rod lock or pilot-operated check valve, or switch to AirTAC SAIL or BSAI cylinders.
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 SAIJ100AX165-100S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 165 mm stroke by up to 100 mm, creating a usable travel window of 65 to 165 mm. It only sets the end position and does not lock the load without live air pressure.
