About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40
The AirTAC SAIJ200X160-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel by up to 40 mm. This creates a precise 120-160 mm usable travel window, perfect for fine-tuning end positions during commissioning without swapping out the entire unit. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This heavy-duty actuator features a robust 40 mm piston rod with an M36x2 thread, utilizing a SUS420J2 stainless steel rod material for enhanced durability against harsh environments. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via a G3/4 PT tapered port. It operates at speeds of 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate the massive load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40 Is Used
Heavy Press Tuning
Dial in the exact 120-160 mm pressing depth during commissioning to accommodate different material thicknesses without machining new hard stops.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching to a new product size, minimizing downtime and keeping the ISO 15552 footprint intact.
Large Load Positioning
Move massive assemblies into a workstation and fine-tune the resting position by up to 40 mm to align with downstream tooling perfectly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-40 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force, such as 15708 N of push thrust at 0.5 MPa, and you need the flexibility to vary the end-stop without external stops. If your setup does not require this level of power, stepping down to a 160 mm bore saves space while still providing 10053 N of push force at 0.5 MPa. The rear adjuster on this SAIJ model acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure. For positive load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder.
Because the 160 mm stroke exceeds the 300 mm threshold where side-loading becomes a major concern, an external guide is recommended to support the rod and prevent premature seal wear. This model uses a PT tapered port thread and is dimensionally interchangeable per ISO 15552. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. As no magnet is specified, it will not work with CMSE or DMSE sensors without modification.

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 SAIJ200 Adjustable Cylinder SAIJ200AX160-40 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 160 mm nominal stroke by up to 40 mm, resulting in a usable travel window of 120-160 mm. It only sets the travel end and does not lock the load without live air pressure.
