About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10
The AirTAC SAIJ200X180-10 is a double-acting, single-rod ISO 15552 profile cylinder engineered for high-force applications. It integrates a rear mechanical stopper that allows you to fine-tune the retract position, providing a usable travel window of 170 to 180 mm without swapping out the unit. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles heavy loads with precision.
This configuration features an SUS420J2 stainless steel rod for enhanced durability against moisture and PT tapered port threads. It operates at speeds of 30-500 mm/s and includes sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to set the end position, meaning it cannot hold the load dynamically without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10 Is Used
Heavy Press Tuning
Dial in the exact 170-180 mm end-stop on heavy pressing machinery during initial setup, ensuring perfect crush depth without machining custom spacers.
Product Changeover
Quickly adjust the retract position on a production line when switching between heavy product variants, using the rear screw to adapt the stroke on the fly.
Heavy-Duty Forming
Leverage the 15708 N push force for bending or forming thick materials, using the fine adjustment to compensate for material spring-back.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10 the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your machinery requires immense thrust—such as 15708 N push at 0.5 MPa—that smaller bores cannot provide. The 10 mm adjustable window is ideal for fine-tuning the end-stop during commissioning or product changeovers, avoiding the need to machine external stops. If your setup demands holding a load in place without constant air pressure, a standard SAIJ is insufficient; you should consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
For a drop-in ISO 15552 replacement, verify the 200 mm bore, 180 mm stroke, PT port threads, and the required mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because this unit lacks the -S magnet option, it cannot host CMSE reed or DMSE electronic sensors without modification. Additionally, while the 40 mm rod and M36x2 thread handle substantial side loads, any stroke near or exceeding 300 mm requires an external guide to prevent rod binding.
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 SAIJ200 Adjustable Cylinder SAIJ200AX180-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 10 mm, creating a 170-180 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
