About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-75
The AirTAC SAIJ160X600-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a rear stroke adjuster that provides a 525-600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 75 mm without adding external stops. Delivering 14074 N of push force at 0.7 MPa, this 160 mm bore profile cylinder handles massive loads with precision.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced resistance to corrosion and surface wear. It utilizes a PT tapered port thread and operates at speeds of 30-500 mm/s. The rear adjuster acts purely as a travel stop to set deceleration and end limits, meaning it will not hold a load dynamically without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-75 Is Used
Heavy Press Tuning
Dial in the exact 525-600 mm end position during heavy press setup, ensuring precise clamp depth without swapping out the entire cylinder.
Product Size Changeover
Adjust the retract stop on the fly when a production line switches to a different pallet or package size, saving downtime on mechanical modifications.
Large Fixture Alignment
Fine-tune the end-stop position of large automated welding or machining fixtures, compensating for mechanical wear over the machine's life.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-75 the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application demands high thrust—such as 14074 N at 0.7 MPa—combined with the flexibility to fine-tune the retract position during machine commissioning or product changeovers. If you need slightly less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa; if you require more, a 200 mm bore provides 21991 N.
Because the 600 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread need careful alignment to manage side loads—always use an external guide for long unsupported travel. To replace an ISO 15552 cylinder, match the 160 mm bore, 600 mm stroke, 75 mm adjustment, PT port threads, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted. For load-holding without live air, select a SAIL or BSAI cylinder instead of relying on the stopper.

- ✓ 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 SAIJ160AX600-75 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 600 mm nominal stroke by up to 75 mm, creating a 525-600 mm usable travel window. This stopper sets the end position and deceleration point but does not lock or hold the load without continuous air pressure.
