About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-100S
The AirTAC SAIJ50X1000-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 50mm bore and a 1000mm stroke, yielding a usable travel window of 900 to 1000mm via its 100mm adjustment screw. At 0.5 MPa it delivers 982N of push force and 825N of pull force. The barrel is extruded aluminum with sensor grooves on both sides, and this specific SKU includes a magnet for CMSE reed and DMSE electronic sensors.
This model uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads (G1/4). The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops. It supports a speed range of 30-800 mm/s and includes variable air cushions at both ends to manage deceleration over the long travel distance.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-100S Is Used
Variable End-Stop Tuning
Dial in the exact clamping or ejection position from 900 to 1000mm during machine setup, allowing rapid product size changeovers without replacing the actuator.
Long-Travel Material Handling
Pushes products along an extended conveyor line, using the rear screw to precisely match the final pusher distance for varying pallet sizes.
Adjustable Ejection Stroke
Ejects machined parts from a long-bed CNC enclosure, fine-tuning the ejection point to accommodate different part geometries on the fly.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-100S the Right Cylinder?
Choose this 50mm bore when an application requires around 982N of push force at 0.5 MPa. If your process needs less force, stepping down to a 40mm bore provides 628N, while moving up to a 63mm bore yields 1559N. The 1000mm stroke approaches the maximum standard limit for this bore, so the 100mm adjustment window is highly valuable for dialing in exact end-of-stroke positions during commissioning or product changeovers without physically swapping the cylinder.
Because the stroke is 1000mm, the unsupported piston rod is susceptible to sagging and side loads; an external guide rail is strongly recommended to prevent premature seal wear. The rear adjuster and air cushions only set the travel end and deceleration rate; they do not hold the load without live air. For true fail-safe load holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. This SAIJ variant accepts the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552.

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 SAIJ50AX1000-100S FAQ
The rear adjuster screw can be dialed in to shorten the effective travel by up to 100mm. This creates a usable stroke window of 900 to 1000mm, allowing you to set the exact end position at commissioning without adding external mechanical stops.
At a 0.5 MPa operating pressure, the 50mm bore provides 982N of push force and 825N of pull force. If operated at 0.7 MPa, the push force increases to 1374N.
