About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10S
The AirTAC SAIJ200X550-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a massive 15708 N push force at 0.5 MPa and uses a SUS420J2 stainless steel rod. The built-in magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
With a 550 mm nominal stroke and a 10 mm adjustment range, the usable travel window is 540-550 mm. This allows you to fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts only as a travel stop, not a lock, so it cannot hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10S Is Used
Heavy Assembly Presses
Dial in the exact 540-550 mm end-stop during commissioning to ensure perfect clamping force on large fabricated components without external spacers.
Product Changeover Systems
Quickly adjust the retract position by up to 10 mm to accommodate slightly different part heights on the same production line.
Heavy-Duty Positioning
Leverage the 15708 N thrust at 0.5 MPa to shift heavy pallets or molds into their final staging area before secondary operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-10S the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (14074 N push at 0.5 MPa) is insufficient for heavy positioning tasks. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. Because the 550 mm stroke is long and the 40 mm rod is heavily loaded, an external guide is recommended to prevent side-load damage.
For drop-in interchangeability, match the 200 mm bore, 550 mm stroke, PT tapered ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. If you need true load-holding without live air, select the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ200AX550-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push at 0.7 MPa.
The rear adjuster screw lets you shorten the 550 mm nominal stroke by up to 10 mm, creating a 540-550 mm usable travel window. It functions as a hard stop for end-position tuning and does not lock the load.
