About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75S
The AirTAC SAIJ160X800-75-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 725 to 800 mm, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops. Delivering massive thrust up to 18095 N at 0.9 MPa, it handles heavy-duty positioning tasks.
This variant includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and is equipped with a magnet for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE solid-state switches. Fluid connections use PT tapered ports sized at G3/4, while the integrated air cushions manage end-of-stroke deceleration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75S Is Used
Heavy Press Setup
Dial in the 725 to 800 mm stroke window during press tooling changeovers to accommodate varying material thicknesses without external spacers.
Variable Product Diversion
Adjust the retract end-stop on the fly to handle different carton sizes on a high-thrust sorting conveyor line.
Large Assembly Jigs
Fine-tune the end position of heavy fixture plates during initial commissioning, relying on the 18095 N thrust at 0.9 MPa to move the load.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75S the Right Cylinder?
Choose this 160 mm bore when 10053 N of thrust at 0.5 MPa is insufficient, or step down to the 125 mm bore which yields 6136 N at 0.5 MPa if your payload is lighter. The 75 mm adjustable stop is ideal for machine setups requiring variable end stops or product-size changeovers, whereas a fixed-stroke SAI cylinder suits static operations. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the nominal stroke is 800 mm, the 40 mm diameter rod and M36x2 thread require an external guide to prevent excessive side-loading on the long unsupported travel. The rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, select a SAIL or BSAI cylinder. 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 SAIJ160AX800-75S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force. At 0.5 MPa, it provides 10053 N push and 9425 N pull.
The rear adjuster screw mechanically limits the retract stroke, allowing you to shorten the effective travel from 800 mm down to 725 mm. It functions as a physical stop and does not lock the load without continuous air pressure.
