About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-30S
The AirTAC SAIJ200X350-30-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks, delivering 15708N of push force at 0.5 MPa. It features a 350mm nominal stroke paired with a rear adjusting screw that provides a 320-350mm usable travel window. This allows you to fine-tune the retract end position during commissioning without swapping hardware.
Built with a SUS420J2 stainless steel rod (code A) and a PT tapered port, this model includes a magnet (-S) for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. Its robust 40mm rod and M36x2 thread handle substantial side loads, though a 350mm stroke still requires an external guide for optimal stability.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-30S Is Used
Heavy Press Tuning
Dial in the exact 320-350mm end position during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Adjust the rear stopper on the fly to handle different package sizes on a high-thrust transfer line.
Large Assembly Fixturing
Leverage 15708N of thrust to seat heavy components, using the fine-tune screw to perfect the final clamping position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-30S the Right Cylinder?
Choose this 200mm bore when 100mm cylinders (providing 3927N push at 0.5MPa) lack the necessary thrust for heavy positioning. The 30mm adjustment range is ideal for product changeovers, letting you shift the end-stop dynamically rather than installing fixed spacers. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air. For secure load-holding, consider an external rod lock or the AirTAC SAIL series.
To match this ISO 15552 footprint exactly, specify a 200mm bore, 350mm stroke, 30mm adjustment, PT ports, and the -S magnet. Mounting options include the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke exceeds 300mm, always use an external guide to prevent rod bending under high side loads.
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 SAIJ200AX350-30S FAQ
At 0.5 MPa it provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from 350mm down to 320mm. It only sets the travel end and does not lock the load without continuous air pressure.
