About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10S
The AirTAC SAIJ100X145-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 145 mm travel to a precise 135-145 mm window during commissioning. It delivers 3927 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for superior corrosion resistance. A built-in magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This model uses a G1/2 port and includes variable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts strictly as a travel stop to fine-tune the retract position without adding external shims, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10S Is Used
Machine Changeover
Dial in the 135-145 mm retract position on the fly when switching product sizes, eliminating the need to swap cylinders or reposition hard stops.
End-Position Tuning
Fine-tune the final retract stroke within a 10 mm window during setup to perfect alignment without machining custom spacers.
Assembly Pressing
Leverage 3927 N of push force at 0.5 MPa for pressing and seating tasks while using the rear screw to set the exact pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10S the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder lacks thrust, as stepping down to an 80 mm bore drops your 0.5 MPa push force to 2513 N. The 10 mm adjustment window is ideal for applications requiring exact end-position tuning during product changeover rather than swapping a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, verify the 145 mm stroke, 10 mm adjuster, G1/2 PT ports, and the -S magnet requirement.
Because the stroke is under 300 mm, side-load stress on the 25 mm rod is moderate, but an external guide is still recommended for heavy lateral loads. For load-holding without continuous air pressure, select a SAIL locking or BSAI clamp-lock cylinder instead, as the SAIJ adjuster is a stop, not a brake. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options.
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 SAIJ100AX145-10S FAQ
The rear adjuster screw lets you shorten the 145 mm nominal stroke by up to 10 mm, providing a usable travel window of 135-145 mm. It acts as a mechanical stop to set the retract position and does not lock the load without air pressure.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. The operating speed ranges from 30-800 mm/s, and it uses a G1/2 port for air supply.
