Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 260mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100
The AirTAC SAIJ100X260-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It provides a usable travel window of 160 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 100 mm during commissioning. This bore delivers substantial thrust, generating 3927 N of push force at 0.5 MPa and peaking at 801 kgf at 1.0 MPa.
The 25 mm carbon steel rod and M20x1.5 thread provide a robust interface for heavy loads, while the extruded aluminum barrel features sensor grooves on both sides for flexible mounting. It supports a speed range of 30-800 mm/s and uses a G1/2 port. The rear adjuster acts purely as a travel stop to set deceleration and end positions; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100 Is Used
Product Changeover
Quickly reconfigure the end-stop distance by up to 100 mm when switching a packaging line to a different carton size.
Press Fit Tuning
Fine-tune the exact bottoming position of a heavy press operation during machine setup without changing hardware.
Diverter Positioning
Adjust the retract distance of a heavy conveyor diverter arm to accommodate varying product widths on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-100 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your tooling weight. The 100 mm adjustment range is ideal for production lines running multiple product sizes, as it allows rapid end-position changes without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, you would need a separate SAIL or BSAI lock cylinder, as the SAIJ adjuster is not a brake.
This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It features a PT tapered port thread, standard carbon steel rod, and no magnet. Because the 260 mm stroke is moderately long, ensure an external guide supports the rod to prevent excessive side-loading.
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 SAIJ100X260-100 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 260 mm down to 160 mm. This allows precise end-position tuning at commissioning without needing external stops, though it does not lock the load without live air.
