About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX130-10S
The AirTAC SAIJ125X130-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 120-130mm usable travel window, allowing you to trim the effective stroke by up to 10mm during commissioning. Delivering 8590N of thrust at 0.7MPa, it handles heavy loads with precision.
This variant includes a SUS420J2 stainless steel rod (A) for corrosion resistance and a -S magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a travel stop to fine-tune end positions, meaning it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX130-10S Is Used
Machine Setup & Changeover
Fine-tune the 120-130mm travel end-position during machine setup or product changeover without adding external stops or swapping cylinders.
Variable End Stops
Dial in the exact 10mm adjustment window to perfect heavy-duty pressing or clamping operations that require precise end-position tuning.
Product-Size Line Changes
Quickly adapt automated line strokes when product dimensions change, leveraging the 8590N force and integrated rear stopper.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX130-10S the Right Cylinder?
Select this 125mm bore when a 100mm cylinder (5497N push at 0.7MPa) lacks force, but a 160mm bore (14074N) is oversized. The 10mm adjustable window is perfect for variable end stops or product-size changeovers, avoiding the need to swap a fixed-stroke SAI cylinder. It uses PT tapered ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Because the stroke is 130mm, side-load is minimal, but always guide the load for long unsupported travels. Remember that neither the rear stopper nor the air cushion acts as a lock; external rod locks or pilot-operated check valves are required to hold loads safely without continuous air.
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 SAIJ125AX130-10S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the nominal 130mm stroke by up to 10mm. This creates a 120-130mm usable travel window for fine-tuning end positions at commissioning without replacing the cylinder.
At 0.7MPa operating pressure, this 125mm bore double-acting cylinder provides 8590N of push thrust and 11045N at 0.9MPa. It operates at speeds of 30-500mm/s.
