About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10
The AirTAC SAIJ100X15-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed for applications requiring exact end-position tuning. It features a 100mm bore and a 15mm nominal stroke, paired with a 10mm adjustment range that creates a highly precise 5-15mm usable travel window. Delivering 3927N of push force at 0.5 MPa, it handles substantial loads within a very compact movement range.
This model is configured with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of AirTAC CMSE reed or DMSE electronic sensors if a magnet is added later. Adjustable air cushions at both ends ensure controlled deceleration even at the standard 30-800mm/s speed range.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10 Is Used
Precision Short-Stroke Clamping
Ideal for heavy-duty clamping where the exact material thickness varies slightly, using the 5-15mm travel window to apply consistent 3927N force without repositioning the entire fixture.
Machine Commissioning Tuning
Allows engineers to fine-tune the end-of-stroke position during initial setup or product changeover, dialing back the 15mm stroke by up to 10mm directly via the rear adjuster screw.
Compact Assembly Pressing
Delivers high pressing force in a tight physical space, leveraging the 100mm bore and SUS420J2 stainless rod for reliable operation in industrial assembly lines.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX15-10 the Right Cylinder?
Selecting this 100mm bore cylinder provides 3927N of push force at 0.5 MPa, making it a robust choice when a 63mm bore (1559N) is insufficient for a heavy clamping task, but a 125mm bore (6136N) would be physically oversized. The 10mm adjustment range is specifically valuable for machine commissioning, allowing operators to dial in the exact 5-15mm travel limit without adding external stops. Because the stroke is only 15mm, side-load stress on the 25mm rod is minimized compared to longer strokes.
When replacing an ISO 15552 cylinder, verify the 100mm bore, 15mm stroke, PT port threads, and the required mounting hardware. SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For dead-pilot load holding, consider an AirTAC SAIL or BSAI series cylinder instead.

- ✓ 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 SAIJ100AX15-10 FAQ
At a standard operating pressure of 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum rated pressure of 1.0 MPa, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the 15mm nominal stroke by up to 10mm, creating a usable travel window of 5-15mm. This stopper sets the end position but does not lock the load without continuous air pressure.
