About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-75S
The AirTAC SAIJ50X260-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 260 mm travel by up to 75 mm, creating a wide 185-260 mm usable positioning window. This adjuster acts purely as a mechanical stop for end-position tuning during commissioning or product changeover; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider the related SAIL or BSAI series instead.
Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, this bore size handles solid mid-range workloads. The piston rod is SUS420J2 stainless steel (code A), providing better corrosion resistance than standard carbon steel. An integrated magnet (-S) enables position sensing across the dual sensor grooves on the extruded aluminum barrel, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-75S Is Used
Machine Changeover
Quickly reposition the retract end-stop by up to 75 mm when switching a packaging line between different carton sizes.
Fixture Clamping
Fine-tune the clamping travel window between 185 and 260 mm during setup to compensate for varying workpiece tolerances.
Process Alignment
Dial in the exact extended position during commissioning without needing to fabricate custom external mechanical stops.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-75S the Right Cylinder?
Choose this 50 mm bore when an application requires precise, variable end-stops without the need to physically swap cylinders or bolt on external stopper blocks. If you need higher thrust, stepping up to a 63 mm bore yields 1559 N push force at 0.5 MPa; stepping down to a 40 mm bore reduces it to 628 N. The PT tapered port threads (G1/4) and M16x1.5 rod thread are standard for this bore size.
Because the 260 mm stroke is relatively long, the 20 mm diameter rod will experience higher leverage under side loads, so an external guide rail is recommended to prevent premature seal wear. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets to ensure the rear adjuster remains accessible.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ50AX260-75S FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 260 mm down to a minimum of 185 mm. This provides a 75 mm tuning window to set the exact retract end-position at commissioning. The adjuster functions as a travel stop and does not lock the load without live air pressure.
At a standard 0.5 MPa operating pressure, it generates 982 N of push force and 825 N of pull force. At its maximum rated pressure of 1.0 MPa, the push force reaches 1767 N.
