About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-40
The AirTAC SAIJ160X170-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 10053N of push force at 0.5 MPa and features a 40mm adjustment range, creating a precise 130-170mm usable travel window for fine-tuning end positions during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic sensors if a magnet is specified later.
This heavy-duty pneumatic actuator utilizes a G3/4 PT port and a 40mm carbon steel rod with an M36x2 thread to withstand high side loads. Instead of relying on fixed stops, the integrated rear screw mechanism allows operators to dial in the exact retract distance without swapping components, while the standard variable air cushion decelerates the massive moving load smoothly at both ends.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-40 Is Used
Heavy Press Tuning
Dial in the 130-170mm travel window during machine commissioning to set the exact contact force for high-tonnage pressing operations without adding external stoppers.
Product Changeovers
Quickly adjust the retract end-position by up to 40mm on automated lines handling varying product sizes, reducing setup downtime between production runs.
Robotic Material Handling
Leverage the 10053N push force and 40mm carbon steel rod to move heavy payloads, relying on the adjustable stop to fine-tune drop-off positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-40 the Right Cylinder?
Selecting this 160mm bore actuator makes sense when your application requires the 10053N push force at 0.5 MPa but demands on-the-fly end-position tuning; if you need less force, stepping down to a 125mm bore yields 6136N. The SAIJ160X170-40 is chosen over a fixed-stroke SAI cylinder when product changeovers require a variable end-stop, letting you trim the 170mm nominal stroke back by up to 40mm. Because the stroke is 170mm, you should ensure proper external guiding to prevent excessive side-loading on the rod.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 160mm bore, 170mm stroke, 40mm adjustment, G3/4 PT ports, and the specific mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI variant.

- ✓ 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 SAIJ160X170-40 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the 170mm nominal stroke by up to 40mm, providing a usable travel window of 130-170mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
