About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75S
The AirTAC SAIJ200X1000-75-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that trims the effective stroke by up to 75 mm, yielding a precise 925-1000 mm usable travel window for product changeovers. Delivering 28274N of push force at 0.9 MPa, it handles heavy loads while the extruded aluminum barrel integrates dual sensor grooves for CMSE and DMSE switches. The integrated -S magnet enables solid-state DMSE electronic or CMSE reed position sensing.
This specific SKU utilizes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. Because the 1000 mm stroke approaches the practical limits for unsupported piston travel, the robust 40 mm rod and M36x2 thread provide high structural rigidity, though an external guide is still strongly recommended to prevent side-loading damage.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75S Is Used
Heavy Machinery Forming
Dial in the exact 925 to 1000 mm end-stop during heavy press setup, accommodating different die heights without replacing the actuator.
Large Material Transfer
Adjusts the retract position on long-stroke conveying lines to handle varying oversized product lengths safely and efficiently.
Automated Assembly Tuning
Fine-tunes the final 75 mm of travel during machine commissioning to perfectly time heavy component seating without adding external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-75S the Right Cylinder?
Choose this 200 mm bore when your application demands up to 3204 kgf at 1.0 MPa, stepping up from a 160 mm bore that yields 2050 kgf. An adjustable rear stopper is selected over a fixed SAI cylinder when a machine requires fine end-position tuning at commissioning without physically swapping hardware or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series instead.
When replacing an ISO 15552 cylinder, verify the 200 mm bore, 1000 mm stroke, 75 mm adjustment range, PT G3/4 ports, and the -S magnet requirement. The SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. Given the 1000 mm stroke, always pair this cylinder with an external linear guide to manage deflection and side loads.

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 SAIJ200BX1000-75S FAQ
It features a rear stopper screw that lets you shorten the nominal 1000 mm stroke by up to 75 mm, providing a usable travel window of 925 to 1000 mm. This allows precise end-position tuning at commissioning without swapping the cylinder.
At the maximum operating pressure of 1.0 MPa, this double-acting cylinder generates a push force of 3204 kgf (approximately 31400N). At 0.5 MPa, it delivers 15708N of push force.
