About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-50
The AirTAC SAIJ200X75-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 25 to 75 mm. Delivering a massive 15708 N of push force at 0.5 MPa, this 200 mm bore actuator is built for heavy-duty positioning tasks. It features a robust SUS304 stainless steel rod (option B) to resist corrosion, and utilizes PT tapered port threads for a reliable high-flow pneumatic connection.
Unlike a fixed-stroke SAI cylinder, the integrated rear stopper screw allows you to fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts only as a travel stop and does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-50 Is Used
Heavy Machinery Setup
Fine-tune the 25 to 75 mm travel window during heavy equipment commissioning to set precise retract positions without machining custom spacers.
Product Changeover
Quickly adjust the end-stop on a 200 mm bore actuator when switching product sizes on a high-force assembly line.
Press Positioning
Leverage 15708 N of thrust at 0.5 MPa and a 50 mm adjustment range to dial in the exact forming position on heavy press tools.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-50 the Right Cylinder?
Choose this 200 mm bore model when your application requires extreme thrust, as it provides 15708 N push and 15080 N pull at just 0.5 MPa. If you need less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa, which might better suit medium-heavy loads without oversizing. The 50 mm adjustment range is particularly valuable for dialing in exact end positions during machine setup or product changeover. Because the 75 mm nominal stroke is short, side-loading is less of a concern, but always ensure the load is guided to prevent rod binding.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 75 mm stroke, PT port threads, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits the FB, CA, CB, and CR mounts. This non-magnetic variant lacks the -S option, so position sensing requires external switches or a later upgrade. For load-holding without live pressure, select a SAIL or BSAI cylinder instead of relying on the SAIJ adjuster.

- ✓ 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 SAIJ200BX75-50 FAQ
At a 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 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 50 mm, providing a usable travel window of 25 to 75 mm. This stopper only sets the end position and does not lock the load without live air.
