About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-50
The AirTAC SAIJ200X250-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, yielding 21991N push force at 0.7 MPa, while its external stopper allows you to fine-tune the effective travel down to a 200 mm minimum, creating a 200-250 mm usable window without swapping the unit.
This bore features a robust 40 mm diameter piston rod and a G3/4 PT tapered port to handle high flow and heavy loads. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the extruded aluminum barrel integrates sensor grooves on both sides for flexible CMSE or DMSE switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-50 Is Used
Heavy Press Tonnage
Delivers up to 3204 kgf for high-force pressing, forming, and riveting operations requiring substantial end-of-stroke impact.
Variable Product Diverter
The 50 mm adjustment window allows a single diverter to rapidly reposition for different package sizes on a packaging line without changing tooling.
Corrosive Environment Actuation
The SUS304 stainless steel rod provides essential resistance against moisture and washdowns in food processing or outdoor heavy machinery.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-50 the Right Cylinder?
Selecting this 200 mm bore makes sense when your application requires up to 3204 kgf maximum force at 1.0 MPa; stepping down to a 160 mm bore drops that to 2050 kgf. The 50 mm adjustment range is ideal for accommodating multiple product sizes on a single conveyor line, acting as a variable end-stop during commissioning rather than requiring fixed-stroke SAI cylinders. Because the rear adjuster is a travel stop and not a locking device, it will not hold the load without live air pressure—integrate a SAIL or BSAI cylinder if true fail-safe load holding is required. With a 250 mm stroke, side-loading is minimal, but any long unsupported tooling should still use an external guide.
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 SAIJ200BX250-50 FAQ
The rear adjuster acts as a mechanical stop that trims the effective travel back by up to 50 mm, giving you a usable 200-250 mm stroke window for fine-tuning end positions during setup.
At 0.5 MPa it provides 15708N push and 15080N pull force, with a maximum thrust of 3204 kgf at 1.0 MPa. The operational speed range for this 200 mm bore is 30-500 mm/s.
