About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-30
The AirTAC SAIJ50X500-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel within a 470-500 mm window. It delivers a robust 982N push force at 0.5 MPa, making it highly suitable for mid-range automation tasks. The extruded aluminum barrel features sensor grooves on both sides for flexible positioning.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced durability against minor moisture, and utilizes PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to set the retract end position during commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-30 Is Used
Machine Changeover
Dial in the 470-500mm travel window during product size transitions to set exact retract positions without adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the retraction point on a sorting pusher to handle different carton lengths on the fly.
Commissioning Calibration
Trim the stroke by up to 30mm during initial setup to perfectly time machine sequencing and prevent mechanical crashes.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-30 the Right Cylinder?
Choose this 50mm bore when your application requires the 982N push force at 0.5 MPa, stepping up from a 40mm bore (628N) for heavier payloads, or down from a 63mm bore (1559N) where space is constrained. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops or quick machine changeovers without physically swapping components.
Because the 500mm stroke is substantial, an external guide is recommended to prevent rod side-loading and premature wear. For load-holding without continuous air pressure, this standard cylinder is insufficient; consider the SAIL or BSAI series instead. ISO 15552 interchangeability ensures it matches standard mounting footprints using Basic, FA, LB, TC, FTC, TCM1, or TCM2 brackets.

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 SAIJ50AX500-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, providing a usable travel window of 470-500mm. It acts as a mechanical stop for end-position tuning and does not function as a lock to hold the load.
At a standard 0.5 MPa operating pressure, the SAIJ50X500-30 delivers 982N of push force and 825N of pull force. It can reach up to 1767N push force at 0.7 MPa.
