About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10S
The AirTAC SAIJ125X60-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 60 mm travel that can be dialed back by up to 10 mm, giving you a precise 50-60 mm usable stroke window for exact end-position tuning during commissioning. Delivering 6136 N of push force at 0.5 MPa, it handles heavy loads without requiring an oversized bore.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes an internal magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the rear adjuster acts purely as a mechanical stop to set deceleration—it is not a locking device.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10S Is Used
Machine Changeover
Fine-tune the 50-60 mm travel window during product size transitions on a packaging line without replacing the cylinder or adding external stops.
Heavy Fixture Clamping
Leverage the 6136 N push force at 0.5 MPa to secure heavy workpieces, using the rear screw to dial in the exact clamping position.
Variable End-Stop Setup
Adjust the retraction end-point precisely during initial commissioning to accommodate minor mechanical tolerances in your assembly.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10S the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires variable end stops or fine-tuning at changeover without swapping out physical components. If your application needs slightly less force, stepping down to a bore 100 unit yields 3927 N of push force at 0.5 MPa. For load-holding without live air pressure, a standard SAIJ cannot hold position; you should pivot to an AirTAC SAIL or BSAI clamp-lock cylinder instead.
To match this ISO 15552 footprint exactly, specify a 125 mm bore, 60 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets found on some other series.

- ✓ 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 SAIJ125 Adjustable Cylinder SAIJ125AX60-10S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 50 to 60 mm. The adjuster acts as a mechanical stop to tune the end position and does not lock the load without live air.
At a 0.5 MPa operating pressure, it generates 6136 N of push force and 5734 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 8590 N.
