About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10S
The AirTAC SAIJ125X10-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a carbon steel piston rod and a PT tapered port. Because the nominal stroke is only 10 mm and the adjustment range is also 10 mm, this specific SKU provides a highly specialized 0-10 mm usable travel window, allowing the effective retraction end-position to be dialed back completely to a zero-stroke mechanical stop.
Belonging to the 125 mm bore class, it generates 6136 N of push force and 5734 N of pull force at 0.5 MPa, making it suited for heavy-duty pressing or clamping tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10S Is Used
Short-Stroke Pressing
Delivers 6136 N of push force at 0.5 MPa for heavy-duty pressing, with the 10 mm adjuster allowing precise calibration of the bottom dead center.
End-Stop Calibration
The 0-10 mm usable travel window lets technicians fine-tune the retraction end-position during machine commissioning without adding external mechanical stops.
Product Changeover
Ideal for lines running variable product sizes, where the rear screw quickly modifies the effective clamping stroke on the fly without swapping the cylinder.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X10-10S the Right Cylinder?
Choose this 125 mm bore model when an application demands high force (6136 N push at 0.5 MPa) over an extremely short, finely tunable distance. If your setup requires less thrust, stepping down to a 100 mm bore yields 3927 N of push force at 0.5 MPa, whereas moving up to a 160 mm bore provides 10053 N. The rear adjustment screw acts purely as a mechanical travel stop for commissioning end-position tuning; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider an SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. The correct mounting accessory set for this SAIJ series includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR options. To replicate this exact configuration, specify a 125 mm bore, 10 mm stroke, 10 mm adjustment, PT port thread, carbon steel rod, and the -S magnet option.

- ✓ 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 SAIJ125 Adjustable Cylinder SAIJ125X10-10S FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. With a 10 mm nominal stroke and a 10 mm adjustment code, the usable travel window is 0-10 mm, allowing the stroke to be trimmed back completely.
No, the rear adjuster functions only as a travel stop to set the end position and does not hold the load without live air. For load-holding, use an SAIL or BSAI cylinder. This -S model includes a magnet for position sensing with AirTAC CMSE reed switches and DMSE electronic sensors.
