About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75S
The AirTAC SAIJ160X700-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 625 to 700 mm. Built with a SUS420J2 stainless steel rod and PT tapered ports, it delivers 14074 N of push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold a load without live air pressure. For position holding without continuous air, an external rod lock or related types like SAIL or BSAI are required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75S Is Used
Heavy Fabrication Setup
Dial in the exact 625 to 700 mm retract position during heavy fabrication machine commissioning without machining new hard stops.
Product Size Changeover
Adjust the end-of-stroke position on a conveyor diverter to accommodate different large pallet sizes on the fly.
Assembly Line Tuning
Fine-tune the clamping reach on a large assembly line fixture, using the 75 mm adjustment window to perfect the end position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 14074 N push force at 0.7 MPa and on-the-fly end-position tuning across a 75 mm range. If your setup only needs the 10053 N push force at 0.5 MPa provided by a smaller bore, stepping down might save space, but the 160 mm class handles significantly heavier loads. The -S magnet enables use with AirTAC CMSE reed and DMSE electronic solid-state sensors for precise position feedback.
Because this model features a 700 mm stroke, the 40 mm rod diameter and M36x2 rod thread must contend with substantial leverage forces; an external guide is highly recommended to prevent excessive side-loading. When matching ISO 15552 interchangeability, confirm the 700 mm stroke, 75 mm adjustment, PT ports, SUS420J2 rod, and your preferred mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this series.
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 SAIJ160AX700-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 18095 N.
The rear adjuster screw allows you to shorten the nominal 700 mm stroke by up to 75 mm, creating a usable travel window of 625 to 700 mm. This stopper sets the end position but does not lock the load without live air pressure.
