About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-75
The AirTAC SAIJ200X260-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This external stopper allows you to fine-tune the effective travel down to a 185-260 mm window, accommodating product changeovers without adding external physical stops or swapping the barrel. It delivers substantial thrust, providing 21991 N of push force and 15080 N of pull force at a 0.7 MPa operating pressure.
Built for demanding environments, this specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The massive 40 mm rod and M36x2 thread provide exceptional rigidity against side loads, though long strokes still require external guiding. Fluid ports are PT tapered G3/4, and the extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches if a magnet is added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-75 Is Used
Heavy Press Tuning
Dial in the exact 185-260 mm end position during machine setup to accommodate varying material thicknesses without re-mounting the cylinder.
Product Changeover
Quickly adjust the retract stopper by up to 75 mm on a packaging line to handle different carton sizes on the fly.
Large Assembly Stops
Use the robust 40 mm rod and M36x2 thread to provide a rigid, adjustable physical stop for heavy-duty automotive assembly fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-75 the Right Cylinder?
Selecting this 200 mm bore adjustable cylinder is ideal when your machine requires precise end-position tuning at commissioning or during format changes, stepping up from a 160 mm bore (which offers 14074 N push at 0.7 MPa) to handle heavy loads up to 3204 kgf at 1.0 MPa. The 75 mm adjustment window lets you dial in the exact retract distance on-site. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 200 mm bore, 260 mm nominal stroke, 75 mm adjustment range, PT G3/4 port, and the SUS420J2 rod material. Since the stroke is 260 mm, external guiding is recommended to manage side loads and prevent premature seal wear. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories.

- ✓ 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 SAIJ200AX260-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 260 mm down to a minimum of 185 mm, providing a 75 mm adjustment window for fine-tuning end positions.
At 0.7 MPa, it provides 21991 N of push force and 15080 N of pull force. At the maximum 1.0 MPa operating pressure, it can deliver up to 3204 kgf.
