About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-10S
The AirTAC SAIJ200X650-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a substantial push force of 15708 Newtons at 0.5 MPa. It features a robust 40 mm SUS304 stainless steel rod (option B) and a PT G3/4 port. Because this is an adjustable-stroke variant, an integrated rear stopper mechanism allows you to fine-tune the end position, creating a usable travel window between 640 and 650 mm without swapping out the hardware.
This 650 mm stroke exceeds standard lengths but remains within the 1500 mm maximum limit for this bore, making it a tailored solution for long-reach applications. The extruded aluminum barrel includes sensor grooves on both sides, and the included -S magnet enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic solid-state switches. Furthermore, the SAIJ series utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets to streamline your design footprint.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-10S Is Used
Heavy Stamping Alignment
Fine-tune the 640-650 mm end position during press setup to ensure perfect alignment of heavy metal components, absorbing impact with the integrated air cushions.
Long-Reach Diverting
Actuate large diverters on wide material handling lines, using the 10 mm stroke adjustment to dial in the exact push distance for varying pallet sizes.
Automated Assembly Jigs
Drive heavy tooling plates over a 650 mm travel window, relying on the SUS304 rod for corrosion resistance in harsh industrial washdown environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-10S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires moving heavy loads, as it provides up to 3204 kgf at 1.0 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may save space and air consumption. The primary advantage of the SAIJ over a fixed SAI cylinder is the rear adjuster screw, which allows for 10 mm of end-position tuning during commissioning or product changeover without adding external stops.
Because the 650 mm stroke is substantial, the 40 mm rod handles significant side loads, but an external guide is strongly recommended to prevent rod bending and premature seal wear over long unsupported travels. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding without continuous air, consider the SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock. To ensure exact ISO 15552 interchangeability, match the 200 mm bore, 650 mm stroke, 10 mm adjustment, PT G3/4 port, and -S magnet specifications.

- ✓ 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 SAIJ200BX650-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear stopper screw allows you to shorten the effective travel by up to 10 mm, creating a usable stroke window of 640 to 650 mm. This enables fine-tuning of the retract end position at commissioning without modifying the machine frame.
