About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10S
The AirTAC SAIJ200X350-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a rear adjusting stopper that allows you to fine-tune the effective stroke within a 340 to 350 mm travel window without adding external stops. This specific configuration includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered port threads.
Operating at 0.5 MPa, this 200 mm bore unit generates 15708 N of push force and 15080 N of pull force. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports CMSE reed and DMSE electronic solid-state switches for precise position feedback. The robust 40 mm rod and M36x2 thread accommodate high side loads, while adjustable air cushions at both ends manage deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10S Is Used
Heavy Press Tuning
Dial in the exact 340-350 mm retraction point on a heavy press during setup, allowing 10 mm of fine adjustment to accommodate different tooling heights without swapping cylinders.
Product Changeover
Quickly adjust the end-stop on a packaging line when switching to a new product size, using the rear screw to shorten the stroke by a few millimeters for precise positioning.
Automated Assembly
Drive large actuators in automated assembly lines where 15708 N of push force is required, relying on the SUS420J2 rod and CMSE/DMSE sensors for reliable operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10S the Right Cylinder?
Selecting this 200 mm bore model is ideal when your application demands extreme thrust, such as 15708 N at 0.5 MPa, and the ability to dial in the retraction end-point by up to 10 mm during commissioning or product changeover. If you need to step down the force to 10053 N, the 160 mm bore variant offers a more compact footprint, but this 200 mm cylinder is unmatched for heavy loads. The rear adjuster functions strictly as a travel stop to set the end position; it does not hold the load without live air. For true position holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series.
Because this is a 350 mm stroke, the 40 mm rod and M36x2 thread provide substantial support, but long unsupported strokes still require an external guide to prevent rod sag and uneven wear. As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. When replacing a unit, match the 200 mm bore, 350 mm stroke, 10 mm adjustment, PT port threads, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ200AX350-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 340 to 350 mm. It is a travel stop for end-position tuning, not a lock, and does not hold the load without live air pressure.
