About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75
The AirTAC SAIJ160X700-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. It features a robust 40mm SUS420J2 stainless steel rod and PT tapered port threads. The integrated -75 adjustment code allows you to dial back the 700mm nominal stroke, creating a precise 625-700mm usable travel window for exact end-position tuning during commissioning.
This heavy-duty actuator utilizes variable air cushions at both ends to decelerate massive loads smoothly across its 30-500mm/s speed range. The rear screw acts purely as a travel stop to fine-tune the retract position without requiring external stops, while the extruded aluminum barrel retains standard sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75 Is Used
Heavy Press Positioning
Dial in the exact 625-700mm end-stop during press setup to accommodate varying material thicknesses without changing tooling.
Pallet Changeover Stops
Adjust the retract distance on the fly to handle different pallet lengths on a single heavy-duty transfer line.
Large Assembly Fixtures
Fine-tune the clamping reach on large automotive or industrial assemblies where a fixed 700mm stroke would lack flexibility.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-75 the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder (providing 3518N push at 0.7 MPa) lacks the thrust for heavy positioning, but a 200mm bore would be excessive. The adjustable 625-700mm travel window is ideal for machinery requiring product-size changeovers, allowing you to reposition the end stop without swapping the cylinder. For any stroke of 700mm, the extended unsupported length means an external guide is required to prevent side-load damage, as even the 40mm rod has limits under high inertia.
To match this ISO 15552 dimensionally interchangeable cylinder, specify: 160mm bore, 700mm stroke, -75 adjustment, PT G3/4 port, and mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster and air cushions only set the travel end; they do not hold the load without live air. For pilot-operated load holding, consider the SAIL or BSAI series instead.
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 SAIJ160AX700-75 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 2050 kgf.
The rear adjuster screw lets you mechanically shorten the 700mm nominal stroke by up to 75mm, providing a usable travel window of 625-700mm. It functions as a physical stop for end-position tuning, not a load-holding lock.
