About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-75S
The AirTAC SAIJ100X150-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 5497N of push force at 0.7MPa and provides a usable travel window of 75 to 150mm, allowing you to dial back the nominal 150mm stroke by up to 75mm during commissioning. This configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet for use with CMSE reed and DMSE electronic sensors.
Because the adjuster acts purely as a mechanical stop at the retract end, it decelerates the piston alongside the standard air cushions but does not lock the load without live air. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets found on other variants.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-75S Is Used
Machine Changeover
Fine-tune the retract distance within the 75-150mm window during product size changes without disassembling the line or bolting on external stops.
Variable End Stops
Dial in the exact end position during initial commissioning to accommodate material thickness variations, utilizing the 75mm rear adjustment screw.
Assembly Positioning
Leverage the 5497N push force at 0.7MPa to press or position components, relying on the SUS420J2 stainless rod for durability in industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-75S the Right Cylinder?
Choose this adjustable-stroke model when your equipment requires frequent product-size changeovers, allowing you to fine-tune the end position without swapping cylinders or adding external stops. If you need higher force, stepping up to the 125mm bore yields 8590N at 0.5MPa, while dropping to the 80mm bore offers 2513N. For load-holding requirements without continuous air pressure, note that the rear adjuster is a stop, not a brake; you should instead select an SAIL locking cylinder, a BSAI clamp-lock, or an external rod lock.
When replacing an ISO 15552 cylinder, match the 100mm bore, 150mm nominal stroke, 75mm adjustment range, PT tapered port threads, and the -S magnet option. The 25mm piston rod and M20x1.5 thread provide robust resistance to side loading, though any stroke over 300mm would still require an external guide to prevent binding.
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 SAIJ100AX150-75S FAQ
At an operating pressure of 0.7MPa, this 100mm bore cylinder generates 5497N of push force and 3681N of pull force. It can reach a maximum push force of 7068N at 0.9MPa.
The rear adjuster screw lets you mechanically shorten the effective travel from the 150mm nominal stroke down to as little as 75mm. This stop works with the air cushions to set the end position but does not hold the load without live air pressure.
