About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-30S
The AirTAC SAIJ200X280-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated -S magnet enables precise position detection with CMSE reed and DMSE electronic sensors.
This specific SKU features a 30mm adjustment range, creating a usable travel window of 250 to 280mm for exact end-position tuning during commissioning. The rod is constructed from SUS420J2 stainless steel for enhanced durability, and air connections use PT tapered threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface strictly supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-30S Is Used
Heavy Press Tuning
Fine-tune the 250-280mm travel window during heavy press setups to accommodate varying material thicknesses without machining new external stoppers.
Product Changeover
Rapidly adjust the end-stop position on automated packaging lines when switching between different large-format product sizes.
High-Force Positioning
Leverage the 15708N push force to shift heavy pallets or molds, using the rear screw to dial in the exact retracted position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-30S the Right Cylinder?
Select this 200mm bore actuator when an application requires extreme force alongside variable end-stops, avoiding the need to physically swap cylinders during product changeovers. If you need less force, stepping down to a 160mm bore yields 10053N push force at 0.5 MPa, but the SAIJ200X280-30-S is necessary for heavy loads up to 3204 kgf at 1.0 MPa. The 40mm diameter rod and M36x2 thread provide high structural rigidity against side loads, though any stroke exceeding 300mm still demands an external guide.
The rear adjuster acts purely as a travel stop to set deceleration points and cannot hold a load without live air pressure. For true fail-safe load holding without continuous air, you must integrate an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamping cylinder. To directly replace an ISO 15552 unit, match the 200mm bore, 280mm nominal stroke, 30mm adjustment, PT port thread, and the -S magnet requirement.

- ✓ 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 SAIJ200AX280-30S FAQ
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates 15708N of push force and 15080N of pull force. At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 280mm nominal stroke by up to 30mm, providing an effective travel window of 250 to 280mm. This stopper fine-tunes the end position during commissioning but does not lock the load without live air pressure.
