About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100S
The AirTAC SAIJ160X145-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 18095N at 0.9 MPa. Its 145 mm nominal stroke can be dialed back by up to 100 mm, creating a highly flexible 45-145 mm usable travel window. This extreme adjustability allows you to fine-tune end positions at commissioning without swapping hardware.
Featuring a carbon steel rod and a PT tapered port, this unit includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100S Is Used
Variable End Stops
Ideal for heavy presses requiring variable end stops, letting operators dial back the stroke by up to 100 mm to accommodate different material thicknesses on the fly.
Machine Changeover
Speeds up product-size changeover on large assembly lines by using the rear screw to set new retraction limits instantly without changing the cylinder.
Heavy Clamping Setup
Provides 14074N of push force at 0.7 MPa for heavy clamping tasks, with fine end-position tuning to prevent crushing delicate workpieces during commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-100S the Right Cylinder?
Choose this 160 mm bore when you need extreme force that smaller bores cannot provide, such as stepping up from a 125 mm bore which yields 11045N at 0.9 MPa. The SAIJ160X145-100-S is selected specifically when a machine setup requires a variable end-stop, allowing product-size changes on a line without adding external stops or buying a fixed-stroke SAI cylinder. Because the stroke is 145 mm, you avoid the long unsupported rod side-load issues seen at 300 mm or more, though heavy loads still require proper external guiding.
When specifying an ISO 15552 replacement, match the 160 mm bore, 145 mm stroke, 100 mm adjustment, PT port thread, and the -S magnet requirement. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is a travel stop, not a lock; if the application requires holding a load without live air pressure, use an AirTAC SAIL or BSAI cylinder instead.

- ✓ 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 SAIJ160X145-100S FAQ
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stopper that lets you trim the effective stroke back from the 145 mm nominal length. This creates a usable travel window of 45 to 145 mm, allowing precise end-position tuning without replacing the cylinder.
