About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30
The AirTAC SAIJ63X130-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a usable stroke window of 100-130 mm, enabling fine end-position tuning at commissioning without swapping out the cylinder or adding external stops. It delivers a robust 1559 N push thrust at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for mid-range industrial actuation.
This variant is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical travel stop to set the retract position; it does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30 Is Used
Machine Changeover Calibration
Dial in the exact retract distance from 100 to 130 mm during product size changes on a packaging line, eliminating the need to physically swap cylinders or reposition external hard stops.
End-Position Tuning
Fine-tune the final end-of-stroke position during commissioning to absorb mechanical tolerances in the fixture, using the rear adjuster to set the precise 30 mm trim window.
Mid-Force Actuation
Leverage the 1559 N push force at 0.5 MPa for pressing, lifting, or clamping tasks where the exact travel distance may vary slightly between production runs.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30 the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when your application requires precise end-stop calibration during machine setup or product changeover, offering a 100-130 mm travel window. If you need less force, stepping down to a 50 mm bore yields 982 N push thrust at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N for heavier payloads. Unlike a fixed-stroke SAI cylinder, the SAIJ rear screw allows on-the-fly adjustments without changing mounting hardware.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 130 mm nominal stroke, 30 mm adjustment range, PT G3/8 port, and your required mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For applications requiring the load to be held mechanically without live air pressure, this cylinder's stopper is insufficient; consider an SAIL lock or BSAI clamp-lock cylinder instead.

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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30 FAQ
It features a rear adjusting screw that mechanically limits the piston's retract travel. For this model, you can trim the nominal 130 mm stroke back by up to 30 mm, providing a usable travel window of 100-130 mm to fine-tune the end position without external stops.
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
