About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100
The AirTAC SAIJ200X175-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708N of push force and 15080N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. The integrated rear stopper allows you to trim the effective travel anywhere within a 75-175 mm window, providing exact end-position tuning without swapping out the entire unit.
This configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic switches cannot be used without modification. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100 Is Used
Heavy Fixture Positioning
Dial in the exact clamping end-position of massive welding or machining fixtures across a 75-175 mm window without machining new stop blocks.
Product Changeover Diverter
Quickly reconfigure a heavy-duty conveyor diverter arm by turning the rear screw to accommodate different pallet sizes on the fly.
Press Stroke Tuning
Fine-tune the bottoming position of a high-force pneumatic press during commissioning to prevent over-travel and tooling damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force that smaller bores cannot provide, such as shifting heavy fixtures. If the full 15708N push at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053N, which may better suit lighter loads while saving physical space. The 100 mm adjustment range is exceptionally wide, making this model ideal for prototyping or machinery that frequently processes varying product sizes and needs the end-stop moved significantly during changeovers.
Because the nominal stroke is 175 mm, an external guide is recommended to manage side loads, as even the robust 40 mm rod can deflect under high stress without proper support. For load-holding without continuous air pressure, this standard SAIJ adjuster will not suffice; you should explore the SAIL air-released lock or BSAI clamp-lock variants. This unit is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ200AX175-100 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 175 mm nominal stroke by up to 100 mm, creating a usable travel window of 75 to 175 mm. It only sets the travel end and does not lock the load without live air pressure.
