About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-30S
The AirTAC SAIJ50X1000-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 982N push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance. With a nominal 1000mm stroke and a 30mm adjustment range, you can fine-tune the retract end-position to achieve an exact 970-1000mm usable travel window.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeover. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-30S Is Used
Variable End-Stop Positioning
Dial in the retract stroke from 970mm to 1000mm during machine setup to achieve exact end-position tuning without swapping out the entire actuator.
Product Changeover Lines
Quickly adjust the travel window to accommodate different product sizes on a conveyor system, using the 30mm rear stopper to adapt the stroke on the fly.
Sensor-Ready Automation
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for precise positioning feedback in automated assembly processes.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX1000-30S the Right Cylinder?
Choose this 50mm bore cylinder when your application requires 982N of push force at 0.5 MPa (or 1374N at 0.7 MPa) alongside a highly variable end-stop. If you need less force, the 40mm bore provides 628N; if you need more, the 63mm bore offers 1559N. The adjustable rear screw allows you to dial back the travel by up to 30mm, making it perfect for setups demanding exact retract positioning without external stopper hardware.
Because the nominal stroke is 1000mm, the 16mm rod and M12x1.25 thread require an external guide to prevent side-load damage over such a long unsupported distance. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, ensure your replacement matches the 50mm bore, 1000mm stroke, 30mm adjustment, PT tapered ports, and -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 SAIJ50 Adjustable Cylinder SAIJ50BX1000-30S FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder provides a push force of 982N and a pull force of 825N. If you increase the pressure to 0.7 MPa, the push force reaches 1374N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 30mm. For this 1000mm stroke model, it creates a usable travel window of 970-1000mm, allowing fine-tuning at commissioning without adding external stops.
