About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75
The AirTAC SAIJ160X85-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 85mm nominal stroke can be dialed back by up to 75mm, creating a 10-85mm usable travel window. This wide adjustment band allows operators to fine-tune end positions during commissioning without swapping hardware.
This unit features a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts only as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75 Is Used
Variable End-Position Tuning
Dial in the exact travel distance between 10mm and 85mm on heavy pressing assemblies without adding external mechanical stops.
Machine Changeover
Quickly reconfigure the stroke window during product size transitions to maintain precise positioning without replacing the cylinder.
Heavy Assembly Setup
Leverage the 10053N push force for robust clamping tasks while retaining the flexibility to shorten the stroke for smaller parts.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75 the Right Cylinder?
Choose this 160mm bore when an application requires heavy thrust (10053N push at 0.5 MPa) but demands variable end-stops for frequent product changeovers, unlike a fixed-stroke SAI cylinder. If your setup requires less force, stepping down to a 125mm bore yields 6136N. To replace an ISO 15552 cylinder, match the 160mm bore, 85mm stroke, 75mm adjustment, PT G3/4 port, and standard mounting.
Because the 75mm adjustment range on an 85mm stroke creates a very short minimum travel distance of 10mm, ensure your external guidance can handle the resulting geometry. For applications needing positive load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ160AX85-75 FAQ
A rear screw stopper lets you trim the effective travel by up to 75mm. This turns the 85mm nominal stroke into a 10-85mm adjustable window, allowing precise end-position tuning at commissioning.
At 0.5 MPa operating pressure, it provides 10053N of push force and 9425N of pull force. It can reach up to 18095N push force at 0.9 MPa.
