About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-30
The AirTAC SAIJ200X550-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 520-550 mm usable travel window, letting you dial back the 550 mm nominal stroke by up to 30 mm during commissioning. Belonging to the highest force class, it delivers 28274 N of push force at 0.9 MPa and a maximum of 3204 kgf at 1.0 MPa.
This unit uses a SUS420J2 stainless steel rod for higher corrosion resistance and features a PT tapered G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop and works with the air cushion to decelerate the load; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-30 Is Used
Heavy Press Tuning
Fine-tune the exact end-of-stroke position on a 200 mm bore press during setup, trimming up to 30 mm off the 550 mm stroke to perfect the crush distance.
Product Changeover
Adjust the retract stopper on the line when switching to a new product size, avoiding the need to physically swap out the entire large pneumatic cylinder.
Long-Stroke Forming
Execute heavy-duty forming operations requiring 28274 N of push force at 0.9 MPa, using the adjustable window to dial in the precise material displacement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-30 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust, such as 21991 N at 0.7 MPa. If you need less force, stepping down to a 160 mm bore yields 14074 N at 0.5 MPa, which may suit lighter duties. The adjustable stroke is ideal for machine setups requiring variable end stops without adding external physical stops. For a fixed-stroke alternative, the standard SAI cylinder is available.
Because this is a 550 mm stroke, the 40 mm rod and M36x2 thread provide robust support, but long unsupported strokes still require an external guide to prevent side-load damage. To replace this ISO 15552 cylinder, match the 200 mm bore, 550 mm stroke, 30 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Since no magnet is specified, it will not work with CMSE or DMSE sensors. For load-holding without live air, consider the SAIL or BSAI series instead of relying on the adjuster.

- ✓ 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 SAIJ200AX550-30 FAQ
At 0.9 MPa, the push force is 28274 N and the pull force is 25134 N. At 1.0 MPa, it reaches a maximum push force of 3204 kgf.
The rear adjuster screw lets you shorten the 550 mm nominal stroke by up to 30 mm, providing a 520-550 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air.
