About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75
The AirTAC SAIJ200X1000-75 is a double-acting ISO 15552 profile cylinder featuring a substantial 200mm bore and a 1000mm nominal stroke. An integrated rear adjusting screw allows you to trim the effective travel back by up to 75mm, creating a precise 925-1000mm usable window. This on-cylinder fine-tuning eliminates the need to swap bodies or bolt on external stops during machine commissioning. Delivering 15708N of push force at 0.5MPa, it is built for heavy-duty positioning.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It uses PT tapered port threads and operates without a magnet. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate massive loads safely.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75 Is Used
Heavy Press Tuning
Dial in the exact 925-1000mm end position during setup to accommodate varying material thicknesses without replacing the cylinder.
Automated Assembly Line
Adjust the retract stop on the fly during product changeovers to position large components accurately.
Long-Stroke Forming
Fine-tune the travel limit for heavy metal-forming tasks where the exact bottoming position must be regulated precisely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75 the Right Cylinder?
Selecting this 200mm bore model makes sense when your application requires extreme thrust, as stepping down to a 160mm bore drops the 0.5MPa push force to 10053N. The 75mm adjustment range is ideal for product changeovers where the exact end-of-stroke position varies slightly between fixtures. Because the nominal stroke is 1000mm, the heavy 40mm rod and M36x2 thread handle significant stress, but an external guide is mandatory to prevent side-load damage over this long unsupported travel.
For ISO 15552 footprint replacement, match the 200mm bore, 1000mm stroke, 75mm adjustment code, PT port thread, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ200BX1000-75 FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the 1000mm nominal stroke by up to 75mm, giving a usable travel window of 925-1000mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
