About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75
The AirTAC SAIJ160X190-75 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty tasks. It features a robust 40 mm carbon steel rod and generates 10053 N of pull force at 0.5 MPa, scaling up to 18095 N at 0.9 MPa. An integrated rear adjusting screw allows you to shorten the effective stroke by up to 75 mm, creating a precise 115-190 mm usable travel window for exact end-position tuning.
This adjuster acts purely as a mechanical stop to set the retract position and relies on the standard variable air cushion for end-of-stroke deceleration. It is not a locking mechanism, so the cylinder cannot hold a load without live air pressure. For position-holding requirements, consider the SAIL or BSAI variants. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet needed for CMSE or DMSE switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75 Is Used
Heavy Press Tuning
Dial in the exact 115 to 190 mm pressing depth during setup, allowing rapid adaptation for different material thicknesses without changing the tooling.
Product Changeovers
Quickly adjust the retract stop on packaging lines to accommodate varying package sizes, minimizing downtime between production runs.
Assembly Station Setup
Fine-tune the end position during initial commissioning to perfectly align heavy components, leveraging the 40 mm carbon steel rod for high rigidity.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust—such as 14074 N push at 0.7 MPa—but demands on-the-fly stroke adjustments during commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N pull.
When replacing an ISO 15552 cylinder, match the 190 mm stroke, 75 mm adjustment range, PT tapered port threads, and the specific mounting bracket. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, explicitly omitting FB, CA, CB, and CR options. Because the 190 mm stroke is relatively short for this large bore, side-load concerns are minimal, but external guides are still recommended 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 SAIJ160X190-75 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw allows you to trim the nominal 190 mm stroke back by up to 75 mm, resulting in a usable travel window of 115 to 190 mm. It functions as a mechanical stop and does not lock the load without air pressure.
