About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-75
The AirTAC SAIJ200X650-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 575 to 650 mm usable travel window, allowing you to dial back the nominal 650 mm stroke by up to 75 mm during machine commissioning. This bore generates massive thrust, delivering 21991 N of push force at 0.7 MPa and peaking at 3204 kgf at 1.0 MPa.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this unit resists corrosion while handling high loads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic sensors if needed later. The rear adjuster acts purely as a travel stop to fine-tune end positions without swapping the cylinder.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-75 Is Used
Heavy Press Tuning
Fine-tune the 575-650 mm travel window during setup to precisely dial in heavy-duty pressing operations without physically swapping out the massive 200 mm cylinder.
Product Size Changeover
Adjust the rear stopper by up to 75 mm to accommodate new product dimensions on the line, enabling rapid format changes and reducing downtime.
Large Assembly Alignment
Leverage the 28274 N push force at 0.9 MPa to seat large components, using the rear screw to perfectly time the end-position deceleration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-75 the Right Cylinder?
Select this 200 mm bore when your application requires extreme force that smaller neighbor bores cannot provide, such as the 160 mm bore which tops out at 14074 N push at 0.7 MPa. The adjustable 75 mm travel window is ideal for product-size changeovers, letting you set variable end-stops on the fly instead of installing fixed-stroke SAI cylinders or external mechanical stops.
Because the 650 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the 40 mm rod and M36x2 thread. Remember that the rear adjuster is a stop, not a lock; the SAIJ200X650-75 will not hold its load without live air pressure. For fail-safe load-holding, use an external rod lock or consider the AirTAC SAIL or BSAI clamp-lock series. For ISO 15552 replacement matching, specify: 200 mm bore, 650 mm stroke, 75 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no -S magnet.

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 SAIJ200AX650-75 FAQ
This 200 mm bore cylinder delivers 15708 N push and 15080 N pull force at 0.5 MPa. At 0.9 MPa, the push force reaches 28274 N, with a maximum push force of 3204 kgf at 1.0 MPa.
The rear external adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 650 mm down to 575 mm. This provides a 75 mm tuning window for precise end-position calibration without changing the cylinder.
