About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX10-10
The AirTAC SAIJ125X10-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 10 mm nominal stroke that can be dialed back by up to 10 mm, yielding a precise 0-10 mm usable travel window for exacting end-position tuning. Delivering 6136 N of push force at 0.5 MPa, it handles heavy positioning tasks with ease.
This model features an SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic sensors if a magnet is added later. The rear adjustment mechanism acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX10-10 Is Used
Short-Stroke Clamping
Provides 6136 N of precise clamping force in automated machining fixtures where the jaw travel must be dialed in exactly within a 0-10 mm window.
Product Changeover
Enables rapid line adjustments for varying component sizes, using the rear screw to fine-tune the retracted end position without swapping cylinders.
Heavy Assembly Press
Delivers reliable thrust for pressing small bearings or pins, allowing operators to trim the stroke back from 10 mm to prevent over-travel damage.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX10-10 the Right Cylinder?
Select this 125 mm bore cylinder when your application requires substantial force—stepping down to a 100 mm bore yields 3927 N push at 0.5 MPa, while this 125 mm model provides 6136 N. The adjustable stroke is ideal for machine setups needing variable end stops during product changeovers, rather than relying on a fixed-stroke SAI cylinder. If your process demands position holding without continuous air pressure, consider an AirTAC SAIL or BSAI series instead, as the SAIJ adjuster is only a stop. Ensure your setup uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), as FB, CA, CB, and CR mounts are omitted.
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 SAIJ125 Adjustable Cylinder SAIJ125AX10-10 FAQ
At 0.5 MPa operating pressure, this 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force. It can achieve a maximum push force of 11045 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm. This creates a 0-10 mm usable stroke window, letting you fine-tune the end position at commissioning without adding external stops.
