About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100
The AirTAC SAIJ100X150-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497N of push force at 0.7 MPa. Its defining feature is the 100mm adjustment range, which creates a highly versatile 50-150mm usable travel window from the 150mm nominal stroke. This allows operators to dial in the exact end position during commissioning without swapping hardware.
This unit features an SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a reduced set of ISO 15552 mounting options: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100 Is Used
Product Changeover
Quickly reconfigure the extended end-stop from 50mm to 150mm on packaging lines running varied carton lengths without changing the cylinder.
Prototype Positioning
Fine-tune the exact clamping reach during machine commissioning to find the optimal mechanical contact point before finalizing fixtures.
Variable End Stops
Provide adaptable physical limits for assembly presses requiring different insertion depths across multiple production batches.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100 the Right Cylinder?
Choose this 100mm bore when a 63mm cylinder (providing 2182N push at 0.5 MPa) is insufficient, but an 80mm bore (3518N at 0.5 MPa) leaves no margin. The generous 100mm adjustment range is ideal for prototyping or lines running multiple product sizes, replacing the need for fixed-stroke SAI cylinders. Because the rear screw acts only as a travel stop and the air cushions handle deceleration, neither will hold a load without live air; for dead-load holding, select an external rod lock or a SAIL/BSAI series cylinder. To match this cylinder exactly, specify: 100mm bore, 150mm stroke, 100mm adjustment, PT G1/2 port, SUS420J2 rod, and no magnet.
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 SAIJ100AX150-100 FAQ
At 0.7 MPa operating pressure, this 100mm bore cylinder provides 5497N of push force and 5155N of pull force. It can reach a maximum push force of 7068N at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the 150mm nominal stroke anywhere down to 50mm, creating a 50-150mm usable travel window. It acts as a physical stop and does not lock the load without continuous air pressure.
