About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-75S
The AirTAC SAIJ200X150-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 150 mm travel back by up to 75 mm, creating a highly flexible 75-150 mm usable window. It delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa. This bore size uses a robust 40 mm diameter carbon steel core, but this specific SKU specifies an SUS420J2 stainless steel rod (code A) for superior corrosion resistance in humid or washdown environments.
Equipped with a magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjustment mechanism acts purely as a mechanical stop to fine-tune the end position at commissioning; it does not lock or hold the load without live air pressure. For applications requiring true fail-safe load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-75S Is Used
Heavy Machinery Changeover
Dial in the 75-150 mm travel window during product size changeovers on large presses, utilizing the rear stopper to set precise end positions without disassembling the line.
Washdown Positioning
Leverage the SUS420J2 stainless steel rod for corrosion resistance in food or chemical processing setups while accurately tuning the stroke end-point to match variable material lengths.
Automated Assembly Tuning
Use the 15708 N thrust to drive heavy tooling heads, adjusting the retract stopper on the fly to accommodate different assembly depths without needing live air to hold the load.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-75S the Right Cylinder?
Choose this 200 mm bore adjustable-stroke cylinder when your application requires the highest force class—stepping down to a 160 mm bore drops your 0.5 MPa push force to 10053 N. The 75 mm adjustment range is ideal for heavy machinery that processes varying product sizes, allowing operators to dial in the exact end-stop without swapping out the cylinder or adding external stops. Because the stroke is 150 mm, you avoid the extreme side-load risks of long unsupported strokes, though the substantial 40 mm rod and M36x2 thread handle significant mechanical stress.
To match this cylinder as an ISO 15552 replacement, verify the 200 mm bore, 150 mm stroke, up to 75 mm adjustment, PT G3/4 tapered ports, and the -S magnet requirement. Mounting options are limited to the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The cylinder operates at speeds of 30-500 mm/s, and its variable air cushions at both ends can be fine-tuned alongside the rear stopper to decelerate heavy 3204 kgf maximum loads smoothly.

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 SAIJ200AX150-75S FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this model, you can trim the 150 mm nominal stroke back by up to 75 mm, giving a usable travel window of 75-150 mm. It only sets the end position and does not lock the load without air pressure.
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf of thrust.
