About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-40
The AirTAC SAIJ160X100-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 60-100 mm, allowing you to dial back the 100 mm nominal stroke by up to 40 mm during commissioning. In the 160 mm bore class, it delivers a robust 10053 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This model features a carbon steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It uses a reduced mounting set—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR options found on some other variants.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-40 Is Used
Heavy Press Tuning
Dial in the exact 60-100 mm travel distance on heavy presses during product changeovers without replacing the cylinder.
Variable End-Stop Setup
Use the 40 mm rear adjustment window to fine-tune the retraction end-position during machine commissioning.
Assembly Line Actuation
Apply the 10053 N push force to move heavy pallets or components, adjusting the stroke as product sizes vary.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-40 the Right Cylinder?
Choose this adjustable-stroke cylinder when your application requires precise end-position tuning without adding external stops or swapping components. If your force requirements are lower, stepping down to a 125 mm bore provides 6136 N of push force at 0.5 MPa. Because the 100 mm stroke is relatively short for this large bore, side-load concerns are minimal, but the load should still be guided externally.
The rear adjuster acts strictly as a travel stop to fine-tune the retraction point; it does not lock or hold the load without live air pressure. For applications requiring fail-safe load holding, consider the SAIL or BSAI series. To match an ISO 15552 replacement, verify the 160 mm bore, 100 mm stroke, 40 mm adjustment, PT G3/4 port, and your required mounting option.
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 SAIJ160 Adjustable Cylinder SAIJ160X100-40 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 100 mm nominal stroke by up to 40 mm, providing a usable travel window of 60 to 100 mm. It sets the end position but does not lock the load without continuous air pressure.
