About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-50
The AirTAC SAIJ100X260-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927 N push force at 0.5 MPa. It features a carbon steel piston rod and PT tapered port threads. By integrating an external adjusting screw, this model allows you to fine-tune the effective travel window down from the 260 mm nominal stroke to anywhere between 210 and 260 mm.
This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding an -S magnet enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear screw acts purely as a travel stop and works alongside the standard variable air cushions to regulate deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-50 Is Used
Product Changeover
Quickly dial the stroke back by up to 50 mm when adapting a packaging line to different carton sizes, avoiding mechanical teardown.
End-Position Tuning
Fine-tune the final retract position during machine commissioning to achieve precise pressing or clamping without adding external stoppers.
Variable End Stops
Provide a flexible 210-260 mm travel window on automated assembly equipment where multiple end-of-stroke positions are required.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-50 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore falls short on thrust, as the 80 mm provides only 2513 N of push force at 0.5 MPa compared to the 3927 N offered here. The 50 mm adjustment range is ideal for machinery requiring frequent product-size changes, allowing operators to dial in the 210-260 mm end position at commissioning without replacing the actuator. Because the nominal stroke is 260 mm, you should ensure adequate external guiding to handle side loads over this travel distance.
For a direct ISO 15552 replacement match, verify a 100 mm bore, 260 mm stroke, 50 mm adjustment, PT port threads, and your preferred mounting style. SAIJ supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster is a stop, not a lock; if your application requires load holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ100 Adjustable Cylinder SAIJ100X260-50 FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 260 mm nominal stroke by up to 50 mm, creating an adjustable travel window of 210 to 260 mm. The adjuster functions as a mechanical stop to set the end position and does not lock the load without live air.
