About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-100
The AirTAC SAIJ200X180-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers immense thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. The integrated rear stopper provides an 80-180 mm usable travel window, allowing you to dial back the 180 mm nominal stroke by up to 100 mm during commissioning.
This heavy-duty actuator uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for position sensing. Because the rear adjuster acts only as a travel stop, it cannot hold loads without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-100 Is Used
Heavy Press Tuning
Fine-tune the 80-180 mm travel window on heavy presses to accommodate varying material thicknesses without repositioning the cylinder.
Product Changeover
Rapidly adjust end-stops on automated lines during product size transitions, saving setup time by avoiding mechanical cylinder swaps.
Clamp Force Calibration
Dial in the exact clamping reach for oversized assemblies, using the 100 mm adjustment range to set precise retract positions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-100 the Right Cylinder?
Select this 200 mm bore model when your application requires maximum force, as it generates 15708N of push force at 0.5 MPa. If your setup needs less than 10000N, stepping down to the 160 mm bore (which provides 10053N at 0.5 MPa) offers a lighter, more compact footprint. Choose this adjustable-stroke version over a fixed SAI when you need variable end-stops for product changeovers without physically swapping the cylinder.
For ISO 15552 replacement matching, ensure you specify the 200 mm bore, 180 mm stroke, 100 mm adjustment range, PT port threads, and the SUS304 (B) rod material. Since this cylinder lacks a magnet, it will not support reed or electronic sensors without modification. The 180 mm stroke is short enough to avoid rod sag, but heavy loads still require external guiding to protect the M36x2 rod thread from side-load damage.
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 SAIJ200BX180-100 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 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 acts as a mechanical stop, allowing you to shorten the 180 mm nominal stroke anywhere down to 80 mm. This creates an 80-180 mm usable travel window for fine-tuning end positions at commissioning. Note that this adjuster is a stop, not a lock, and cannot hold the load without live air pressure.
