Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-30
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 155mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-30
The AirTAC SAIJ200X155-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty tasks. It yields 15708N of push force and 15080N of pull force at 0.5 MPa, scaling up to a 3204 kgf maximum at 1.0 MPa. A 40 mm carbon steel piston rod paired with a PT G3/4 tapered port handles substantial pneumatic flows and structural loads. The standard extruded aluminum barrel features sensor grooves on both sides, though this specific SKU omits the magnet for position sensing.
The -30 adjustment code creates a usable travel window between 125 and 155 mm. This built-in rear stopper lets you dial in the exact end-of-stroke position during commissioning without fabricating external shims. The adjuster acts purely as a travel stop to set deceleration limits, meaning it cannot hold a load dynamically without continuous air pressure. For true static load-holding on heavy assemblies, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-30 Is Used
Heavy Press Tuning
Fine-tune the 125-155 mm travel window on heavy metal stamping presses to achieve precise bottom-dead-center positioning without adding external mechanical stops.
Product Changeover
Quickly adapt clamping positions on automated assembly lines during product size transitions by dialing the rear adjuster rather than re-piping the station.
Large Mold Handling
Leverage the 15708N push force at 0.5 MPa to shift heavy injection molds into place while using the 30 mm stroke trim to perfect the final seating alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-30 the Right Cylinder?
Selecting this 200 mm bore over the neighbouring 160 mm bore trades the 10053N push force (at 0.5 MPa) for a formidable 15708N, which is necessary when moving heavy platens or large industrial molds. The adjustable stroke is ideal for production lines running mixed product sizes, as the 30 mm trim window accommodates varied end-stop requirements without physically swapping the cylinder. Because the total stroke is 155 mm, it falls below the 300 mm side-load threshold, though the robust 40 mm rod still provides excellent resistance to minor deflection.
When replacing an ISO 15552 cylinder, match these exact parameters: 200 mm bore, 155 mm stroke, 30 mm adjustment range, PT G3/4 ports, and no position magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR variants. If you need electronic or reed position feedback, you must specify the -S magnet option for CMSE or DMSE switches.

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 SAIJ200AX155-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it delivers up to 3204 kgf of thrust.
The rear adjuster acts as a mechanical stop that trims the effective travel back by up to 30 mm, creating a usable stroke window of 125 to 155 mm. It allows precise end-position tuning during setup but does not lock the load without live air pressure.
