About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100S
The AirTAC SAIJ160X375-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 275 to 375 mm usable travel window, allowing you to dial back the 375 mm nominal stroke by up to 100 mm during commissioning. Built with a SUS304 stainless steel rod and a PT tapered port, it generates 14074 N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides to accommodate CMSE reed and DMSE electronic switches.
This model uses an external adjusting screw at the rear to set the retract end-position without swapping the cylinder or adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100S Is Used
Heavy Machinery Setup
Fine-tune the retract position of large actuators during equipment commissioning without machining custom spacers.
Product Line Changeover
Quickly adjust the end-stop by up to 100 mm when switching between product sizes on a high-force assembly line.
Variable End-Stop Forming
Dial in the exact 275 to 375 mm travel distance required for pressing or forming different material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires substantial thrust, such as 10053 N at 0.5 MPa, but needs fine-tuning of the end-of-stroke position during machine setup or product changeover. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa. Because the 375 mm stroke is relatively long, the 40 mm rod diameter and M36x2 thread provide rigidity, but an external guide is recommended to prevent side-loading damage.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 375 mm stroke, 100 mm adjustment range, PT G3/4 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The operating speed is 30-500 mm/s.
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 SAIJ160BX375-100S FAQ
The rear adjuster screw allows you to shorten the effective travel from 375 mm down to a minimum of 275 mm, providing a 100 mm tuning window. It functions as a mechanical stop and does not lock the load without sustained air pressure.
At 0.7 MPa operating pressure, the push force is 14074 N and the pull force is 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
