About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX25-10
The AirTAC SAIJ80X25-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a robust 2513N push force at 0.5 MPa while allowing technicians to dial back the 25mm nominal stroke by up to 10mm, creating a precise 15-25mm usable travel window for exacting end-position tuning.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves for CMSE reed or DMSE electronic switches, though no magnet is installed on this specific configuration.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX25-10 Is Used
Precision Clamping
Dial in the exact 15-25mm clamping depth during machine commissioning to prevent workpiece deformation without changing the cylinder.
Product Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate slight variations in part sizes on the assembly line.
Short-Stroke Ejection
Utilize the 2513N push force for short, powerful ejection strokes where the exact ejection endpoint must be fine-tuned on-site.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX25-10 the Right Cylinder?
Select this 80mm bore actuator when an application demands high thrust combined with exact end-stop calibration. If the 2268N pull force at 0.5 MPa is excessive, stepping down to a 63mm bore yields 1402N, whereas larger 100mm bores push 3927N. The adjustable rear stopper is ideal for machine setup and product changeovers, eliminating the need to swap cylinders or bolt on external stops. For load-holding without live air pressure, note that this adjuster acts only as a travel stop and not a lock; an external rod lock or SAIL cylinder is required for true positioning hold. When replacing an ISO 15552 unit, match the 80mm bore, 25mm stroke, 10mm adjustment, PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.
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 SAIJ80 Adjustable Cylinder SAIJ80AX25-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 25mm nominal stroke by up to 10mm, providing a usable travel window of 15-25mm. It only sets the travel end and does not lock the load without live air.
