Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-75
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-75
The AirTAC SAIJ160X150-75 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper that allows you to shorten the effective stroke. It provides a usable travel window of 75-150 mm, giving you significant flexibility to dial in the exact retract position during commissioning without swapping out the unit. In this configuration, the standard carbon steel piston rod and tapered PT port threads handle heavy loads, yielding 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
Because this is a profile cylinder with an extruded aluminum barrel, it features sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to set end-position deceleration alongside the variable air cushions; it is not a lock and cannot hold a load without live air pressure. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1 and TCM2 brackets, omitting the FB, CA, CB and CR options found on some other series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-75 Is Used
Heavy Press Tonnage Setup
Fine-tune the retract distance of a large forming press during initial setup, using the 75 mm adjustment window to perfectly position the 10053 N pull force without adding external mechanical stops.
Product Size Changeovers
Adapt a heavy-duty diverter on a packaging line to handle different pallet heights by adjusting the rear stopper, shifting the travel window between 75 and 150 mm on the fly.
Large Assembly Jigs
Dial in the exact end-of-stroke position for a multi-ton assembly fixture, relying on the ISO 15552 mounting footprint and robust 40 mm carbon steel rod to manage substantial actuation mass.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-75 the Right Cylinder?
Selecting this 160 mm bore is appropriate when your application requires substantial thrust, such as the 14074 N push force available at 0.7 MPa. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N of push force at the same pressure, whereas moving up to a 200 mm bore provides 21991 N. The 75 mm adjustment range on this 150 mm nominal stroke is exceptionally wide, making it ideal for product-size changeovers on a line where the retract distance varies significantly between runs.
For any load-holding requirements without continuous air pressure, this plain SAIJ cylinder is insufficient because the adjuster only acts as a stop. You would need to look at the SAIL series with an air-released lock or the BSAI clamp-lock variant instead. To achieve a drop-in ISO 15552 replacement, match the 160 mm bore, 150 mm stroke, 75 mm adjustment code, PT tapered port thread, standard carbon steel rod, and the appropriate mounting bracket. Since the nominal stroke is 150 mm, side-loading is less of a concern than on longer strokes, but an external guide should still be used for heavy off-center loads.
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 SAIJ160X150-75 FAQ
This 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.7 MPa. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf of thrust.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 150 mm down to as little as 75 mm, creating a 75-150 mm usable window. It only sets the end position and does not lock the load without live air pressure.
