About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100
The AirTAC SAIJ200X650-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed for heavy-duty applications. It features a robust 40 mm carbon steel rod and delivers a substantial push force of 15708 N at 0.5 MPa. With a nominal 650 mm stroke, the external rear stopper allows you to dial back the effective travel by up to 100 mm, creating a precise 550 to 650 mm adjustable window. This means you can fine-tune the end position at commissioning without swapping out the cylinder or adding external stops.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid supply is routed through PT (tapered) G3/4 ports, and variable air cushions at both ends manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster acts solely as a travel stop to set the end position; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100 Is Used
Heavy Press Tuning
Dial in the exact 550-650 mm end position for large metal-forming presses during initial commissioning or die changes without external stopper blocks.
Product Size Changeover
Adjust the retract stroke on packaging lines to accommodate different pallet or product lengths quickly, ensuring precise downstream positioning.
Large Fixture Setup
Fine-tune the clamping reach on heavy automated welding fixtures, using the 100 mm adjustment window to compensate for tooling tolerances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100 the Right Cylinder?
Choose this 200 mm bore cylinder when an 80 mm bore unit falls short, as the 80 mm provides only 2513 N push force at 0.5 MPa compared to the 15708 N available here. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match. When replacing an ISO 15552 cylinder, match the 200x650 dimensions, the 100 mm adjustment range, PT G3/4 port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). No magnet is specified for this unit, so CMSE or DMSE sensors cannot be used without modification. Given the 650 mm stroke, the long unsupported piston rod is susceptible to side-loading; an external guide mechanism is recommended to prevent premature seal wear.
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 SAIJ200AX650-100 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum pressure of 1.0 MPa, it delivers a push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that can shorten the 650 mm nominal stroke by up to 100 mm, providing a usable travel window of 550 to 650 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
