About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-20
The AirTAC SAIJ160X75-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 14074N of push force at 0.7 MPa and up to 18095N at 0.9 MPa. By integrating a 20mm adjustment mechanism, this unit provides a usable travel window of 55-75mm, allowing you to dial in the exact retract endpoint without swapping out hardware.
This variant features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads (G3/4) for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, the design readily accepts CMSE reed or DMSE electronic sensors on magnet-equipped variants for position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-20 Is Used
Heavy Press Tuning
Dial in the exact 55-75mm clamping depth on heavy metal forming presses during setup, ensuring precise deformation without over-traveling the stroke.
Product Changeover
Adapt automated machinery quickly for new part sizes by turning the rear screw, shifting the end-of-stroke position to accommodate different workpiece heights instantly.
Heavy Load Positioning
Move substantial payloads with up to 18095N of push force at 0.9 MPa, using the adjustable stop to fine-tune the resting position for large industrial assemblies.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-20 the Right Cylinder?
Selecting this 160mm bore cylinder is ideal when an application demands high force that smaller neighbors cannot provide, easily outperforming a 125mm bore that yields 8590N push at 0.7 MPa. The adjustable stroke is specifically beneficial during machine commissioning or product changeover, enabling variable end-stops without adding external physical stops. For load-holding requirements without live air pressure, note that the rear adjuster functions strictly as a travel stop and not a brake; you should instead specify an AirTAC SAIL or BSAI locking cylinder. To ensure a true ISO 15552 replacement match, verify the 75mm stroke, 20mm adjustment, PT port, and your preferred mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160AX75-20 FAQ
This 160mm bore cylinder generates a push force of 10053N at 0.5 MPa, 14074N at 0.7 MPa, and 18095N at 0.9 MPa. The pull force is 9425N at 0.5 MPa and 15080N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel. With a 75mm nominal stroke and a 20mm adjustment range, you can tune the usable travel window anywhere between 55mm and 75mm to meet your exact positioning requirements.
