About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-30S
The AirTAC SAIJ200X475-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 15708 N push force at 0.5 MPa and features a 475 mm nominal stroke that can be fine-tuned backward by up to 30 mm, yielding a usable travel window of 445-475 mm. This built-in adjuster allows you to dial in the exact retract end-position at commissioning without swapping the cylinder or adding external stops. It includes a magnet for CMSE and DMSE sensors, uses SUS420J2 stainless steel for the rod, and has PT tapered port threads.
The adjuster acts purely as a mechanical travel stop that sets the end-of-stroke deceleration point alongside the variable air cushions; it does not hold the load without live air pressure. For position holding without continuous air, an external rod lock or pilot-operated check valve is required. The extruded aluminum barrel features sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 445-475 mm retract position during heavy press commissioning without swapping out the entire cylinder or adding spacer blocks.
Product Size Changeover
Quickly adapt the end-stop on a heavy-duty conveyor diverter when package sizes change, utilizing the 30 mm adjustment window to vary the travel distance.
Automated Assembly Setup
Precisely set the end-of-stroke position for a 15708 N assembly press, ensuring perfect clamping force without relying on external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-30S the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands very high thrust (15708 N push at 0.5 MPa) and a variable retract end-stop. The 30 mm adjustment window is ideal for product changeovers or fine-tuning machine setup without machining external stopper blocks. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, whereas moving up is impossible as this is the largest standard size. Because the 475 mm stroke is relatively long, the 40 mm rod diameter and M36x2 thread provide substantial rigidity, but an external guide is still recommended to prevent side-load damage over long unsupported travel. To match this ISO 15552 replacement exactly, specify the 475 mm stroke, 30 mm adjustment, PT ports, SUS420J2 rod, and the -S magnet.

- ✓ 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 SAIJ200AX475-30S 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 operating pressure of 1.0 MPa, it delivers a maximum push force of 3204 kgf.
The rear adjuster screw allows you to shorten the 475 mm nominal stroke by up to 30 mm, giving an effective travel window of 445-475 mm. It functions as a travel stop to tune the end position and deceleration, but it is not a lock and will not hold the load without live air pressure.
