About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20S
The AirTAC SAIJ200X290-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa. A PT tapered G3/4 port feeds the 40mm cushioned chambers. The integrated -S magnet enables position sensing with CMSE reed or DMSE electronic switches.
This specific SKU features a 290mm nominal stroke that can be dialed back by up to 20mm, creating a 270-290mm usable travel window. It carries a SUS304 stainless steel rod for corrosion resistance and includes sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop for fine-tuning end positions at commissioning, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 270-290mm end position on large assembly presses without swapping out the entire cylinder during setup.
Product Size Changeover
Quickly adapt the stroke window for varying large-component sizes on a conveyor line by turning the rear adjuster screw.
Variable End-Stop Machining
Establish precise, repeatable travel limits for heavy-duty machining fixtures requiring a 0.15-1.0 MPa operating pressure.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX290-20S the Right Cylinder?
Choose this 200mm bore when 160mm falls short, as the 160mm class only provides 10053N push at 0.5 MPa. The 20mm adjustment range is ideal for variable end-stops or machine changeovers, preventing the need to swap cylinders or bolt on external stops. Because the 290mm stroke approaches the threshold where rod deflection increases, ensure adequate external guiding to handle side loads. For load-holding without live air pressure, select the SAIL or BSAI series, as this SAIJ adjuster only decelerates travel. To match this ISO 15552 replacement: 200mm bore, 290mm stroke, 20mm adjust, PT G3/4 port, SUS304 (B) rod, -S magnet, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mountings.

- ✓ 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 SAIJ200BX290-20S FAQ
At 0.5 MPa, this 200mm bore cylinder delivers 15708N of push force and 15080N of pull force. It reaches a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 290mm nominal stroke by up to 20mm, providing a 270-290mm travel window. This stopper fine-tunes the end position but does not lock the load without live air.
