About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30
The AirTAC SAIJ160X75-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 45-75 mm usable travel window. Delivering 10053 N of pull force at 0.5 MPa, this large-bore actuator handles heavy loads with precision. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This model uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjustment screw acts strictly as a travel stop to fine-tune the retract position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30 Is Used
Heavy Press Fit Tuning
Dial in the exact 45-75 mm retract position during heavy press operations, allowing precise alignment of large components without adding external mechanical stops.
Product Changeover
Quickly adjust the end-stop for varying product sizes on a high-force assembly line, utilizing the 30 mm adjustment window to switch setups rapidly.
Large Assembly Clamping
Apply up to 10053 N of pull force at 0.5 MPa to secure heavy industrial assemblies, using the rear stopper to fine-tune the clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-30 the Right Cylinder?
Choose this 160 mm bore when 125 mm falls short (providing only 5734 N pull at 0.5 MPa) or if 200 mm is too bulky (delivering 15080 N pull). The 30 mm adjustment range is ideal for dialing in exact end positions during machine setup or product changeover without swapping the cylinder. Fluid must be filtered air, operating at 0.15-1.0 MPa with a speed range of 30-500 mm/s.
Dimensionally interchangeable per ISO 15552, this cylinder uses a PT tapered port thread (G3/4) and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Because the 75 mm stroke is relatively short for this large bore, side-load is minimal, but always ensure proper alignment to prevent premature seal wear.
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 SAIJ160AX75-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. It can deliver up to 18095 N push at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 75 mm stroke by up to 30 mm, creating a usable travel window of 45-75 mm. This stopper fine-tunes the end position but does not hold the load without continuous air pressure.
