About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-75
The AirTAC SAIJ200X375-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 375 mm travel by up to 75 mm. This creates a 300-375 mm usable window, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing requires adding one or using external switches. The rear adjuster acts purely as a travel stop to set the retraction end, not as a lock, so live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-75 Is Used
Heavy Machinery Changeover
Dial in the 300-375 mm travel window during product family changeovers to set new retraction endpoints without physically swapping out heavy actuators.
Large Press Positioning
Leverage the 15708 N push force at 0.5 MPa for large pressing operations, using the rear stopper to fine-tune the exact bottoming position on the fly.
Variable End-Stop Setup
Avoid adding external mechanical stops on large automated assemblies; the built-in 75 mm adjustment range handles the final position tuning directly at the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-75 the Right Cylinder?
Choose this 200 mm bore when you need immense force that smaller neighbors cannot provide; for context, a 160 mm bore yields 10053 N push at 0.5 MPa, while this 200 mm bore reaches 15708 N. The adjustable stroke is ideal for product-size changeovers on a line, letting operators set a variable end-stop quickly. If your application requires holding a load without continuous air pressure, the standard SAIJ adjuster will not function as a brake—consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI locking cylinder variants.
Because the 375 mm stroke is substantial, the 40 mm rod diameter and M36x2 rod thread provide rigidity, but long unsupported strokes still require an external guide to prevent side-loading damage. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints and uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed is 30-500 mm/s, and the PT port size is G3/4.

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 SAIJ200BX375-75 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 the maximum 1.0 MPa pressure, it achieves a maximum push force of 31416 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its nominal 375 mm down to 300 mm. This provides a 300-375 mm adjustable travel window for fine-tuning the end position during setup, but it does not lock the load without live air pressure.
