About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50S
The AirTAC SAIJ200X230-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 230 mm stroke by up to 50 mm. This creates a precise 180-230 mm usable travel window, enabling exact end-position tuning at commissioning without swapping out the unit or fabricating external mechanical stops. Delivering 15708 N of push force at 0.5 MPa, it provides robust actuation for heavy-duty machinery.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a piston magnet (-S) for compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G3/4 PT tapered ports ensure high flow capacity for its 30-500 mm/s operating speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50S Is Used
Heavy Press End-Tuning
Dial in the exact 180-230 mm clamping distance on heavy presses during setup, allowing precise end-position tuning without machining custom spacers.
Product Line Changeover
Quickly adjust the retract stop for different product sizes on a packaging line, shifting the effective stroke by up to 50 mm to accommodate varying material heights.
Heavy-Duty Material Handling
Move substantial loads along a conveyor system with 15708 N of thrust, relying on the 40 mm stainless steel rod to withstand industrial plant environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50S the Right Cylinder?
Choose this 200 mm bore actuator when your application demands the highest thrust class in the SAIJ range, generating up to 21991 N of push force at 0.7 MPa. If you do not require this level of power, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may be more efficient for standard automation. The adjustable stroke is ideal for product changeovers where the end-stop distance varies, but remember the rear adjuster acts only as a travel stop; it does not lock the load. For true fail-safe load holding without live air pressure, select the SAIL or BSAI series instead.
Because this cylinder features a 230 mm stroke, the 40 mm diameter rod and M36x2 thread provide substantial rigidity, though any application approaching or exceeding 300 mm of travel should incorporate an external guide rail to manage side loads. When matching ISO 15552 dimensions for a replacement, verify the 200 mm bore, 230 mm stroke, 50 mm adjustment range, G3/4 PT ports, and the integrated magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on other series.

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 SAIJ200AX230-50S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 230 mm down to as little as 180 mm. This allows fine-tuning of the end position during commissioning, but it does not lock the load without continuous air pressure.
