About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20
The AirTAC SAIJ200X900-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a rear stopper mechanism that allows you to trim the effective stroke, providing a usable travel window of 880 to 900 mm without swapping out the barrel. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore profile cylinder handles massive loads with ease. The rod is constructed from SUS420J2 stainless steel, offering enhanced durability and corrosion resistance for demanding environments.
Unlike fixed-stroke actuators, this adjustable model lets you dial in the retract end during commissioning or product changeover. The rear adjuster works alongside variable air cushions at both ends to decelerate the load smoothly. It is important to note that this adjuster is a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider exploring the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20 Is Used
Heavy Press Fine-Tuning
Dial in the exact 880-900 mm retract position during heavy press commissioning without machining custom external stopper blocks.
Product Line Changeover
Quickly adjust the end-stop by up to 20 mm when switching between product sizes on a high-force automated assembly line.
Long-Stroke Alignment
Precisely set the extended position of heavy materials over a 900 mm travel distance, using the rear stopper to perfect the datum.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-20 the Right Cylinder?
Selecting the SAIJ200X900-20 is ideal when a machine setup requires a massive 15708 N push force at 0.5 MPa combined with a variable end-stop. If your application only requires 10053 N of push force, stepping down to the 160 mm bore reduces physical footprint and air consumption. Conversely, if you need to fine-tune the travel distance on the fly rather than relying on a fixed 900 mm stroke, this adjustable unit surpasses the standard SAI series. The cylinder features a PT tapered G3/4 port and omits the FB, CA, CB, and CR mounting options, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.
Because this model features a 900 mm stroke, the 40 mm diameter piston rod will experience significant leverage forces during extension. An external guide must be used to prevent side-loading damage to the rod and barrel. The rod material is SUS420J2 stainless steel (code A), and the unit lacks a magnet for sensors; if position feedback is needed, a fixed SAI model with the -S option and CMSE reed or DMSE electronic sensors would be required.

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 SAIJ200AX900-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear external adjuster screw acts as a mechanical stop, allowing you to shorten the 900 mm nominal stroke by up to 20 mm, resulting in an effective travel window of 880 to 900 mm. It sets the end position but does not lock the load without continuous air pressure.
