About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30S
The AirTAC SAIJ200X230-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 230 mm nominal stroke that can be fine-tuned backward by up to 30 mm, yielding a usable travel window of 200 to 230 mm. Belonging to the 200 mm bore class, it delivers massive thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to mount AirTAC CMSE reed or DMSE electronic solid-state switches exactly where needed. The rear adjuster functions strictly as a travel stop to dial in the end position during commissioning, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30S Is Used
Heavy Machinery Setup
Dial in the 200 to 230 mm end-stop during heavy machinery commissioning to achieve precise mechanical positioning without machining new spacer blocks.
Product Size Changeover
Quickly adapt a production line for different product heights by turning the rear adjuster up to 30 mm, shifting the stroke end position on the fly.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or tooling bases, using the fine-tuned travel window to prevent mechanical overtravel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-30S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force, such as 21991 N of push at 0.7 MPa. If your load demands less thrust, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may better suit medium-duty setups. The adjustable 200 to 230 mm travel window is ideal for product-size changeovers on a line, allowing you to shift the end-stop without physically swapping the cylinder or adding external stops. Because the 230 mm stroke exceeds the 300 mm side-load threshold, an external guide is recommended to prevent rod deflection. To match this exact ISO 15552 footprint, specify a 200 mm bore, 230 mm stroke, 30 mm adjustment, PT tapered port, and the -S magnet. Note that a plain SAIJ does not hold position without live air; for pilot-operated load holding, consider the SAIL or BSAI series.
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 SAIJ200AX230-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm, creating a usable travel window of 200 to 230 mm. It only sets the end position and does not lock the load without continuous air pressure.
