About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-40
The AirTAC SAIJ200X650-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel by up to 40 mm for a usable window of 610 to 650 mm. Delivering 15708 N of push force at 0.5 MPa, it handles heavy loads while maintaining the standard ISO 15552 mounting interface. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This specific SKU utilizes a SUS304 stainless steel rod for superior corrosion resistance, paired with PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air pressure. For applications requiring positive load-holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-40 Is Used
Heavy Press Tuning
Fine-tune the 610-650 mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without swapping cylinders.
Product Size Changeover
Rapidly adjust the end-stop position on a conveyor handling varying product lengths, using the 40 mm rear screw to adapt the stroke on the fly.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 2805 N of thrust at 0.9 MPa in washdown or corrosive manufacturing environments requiring robust actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-40 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires substantial thrust, stepping up from the 160 mm bore class that provides 10053 N of push force at 0.5 MPa. The 40 mm adjustment range is ideal for product changeovers or fine-tuning the end-of-stroke position without machining external stopper blocks. Because the 650 mm stroke exceeds 300 mm, an external guide is recommended to prevent excessive side-loading on the rod.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 650 mm stroke, 40 mm adjustment, PT G3/4 port, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this configuration omits the FB, CA, CB, and CR mounts. As a standard profile cylinder, it does not include a magnet for position sensing.

- ✓ 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 SAIJ200BX650-40 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 610 to 650 mm. It acts as a mechanical stop to decelerate the piston and set the exact end position, but it does not lock the load without continuous air pressure.
At an operating pressure of 0.5 MPa, the SAIJ200X650-40 provides a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
