About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-50S
The AirTAC SAIJ200X90-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 90 mm travel by up to 50 mm for a highly versatile 40-90 mm usable window. Delivering immense thrust, it provides 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing via CMSE reed or DMSE electronic switches. It features PT tapered port threads (G3/8), dual-sided sensor grooves on the extruded aluminum barrel, and variable air cushions at both ends to manage deceleration across its 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-50S Is Used
Heavy Press Fine-Tuning
Dial in the exact end-of-stroke position for high-force pressing tasks, adjusting the travel window between 40 and 90 mm to accommodate different material thicknesses without changing hardware.
Product Line Changeover
Rapidly reconfigure automated heavy machinery for new product sizes by turning the rear stopper screw, saving downtime on the factory floor.
Variable End-Stop Positioning
Set precise retraction limits on large actuators where standard fixed strokes fail to provide the flexibility needed for multi-format operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-50S the Right Cylinder?
Choose this 200 mm bore when your application demands extreme force that exceeds the 10053 N push available from the neighbouring 160 mm bore at 0.5 MPa. The rear adjuster screw acts purely as a mechanical travel stop to fine-tune the end position during commissioning or product changeover without swapping out the cylinder; it does not hold the load without live air pressure. For true fail-safe load holding, select the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match these exact specifications: 200 mm bore, 90 mm nominal stroke, 50 mm adjustment range, PT G3/8 ports, and a magnet for -S sensing. Because the stroke is short at 90 mm, side-load stress on the 40 mm rod is minimal, though external guidance is always recommended for heavy loads.
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 SAIJ200BX90-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw functions as an external stopper that lets you shorten the effective stroke from its nominal 90 mm down to as little as 40 mm. This creates a 40-90 mm adjustable travel window, allowing you to fine-tune end positions without adding external stops.
