About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10
The AirTAC SAIJ125X60-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 60mm nominal travel by up to 10mm. This creates a 50-60mm usable end-position window, providing immediate fine-tuning at commissioning without adding external stops. Delivering 6136N of push force at 0.5MPa, it handles heavy loads with ease.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches. Mounting options cover the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10 Is Used
Press Fit Commissioning
Dial in the exact 50-60mm insertion depth for heavy-duty press fits during machine setup, ensuring perfect contact without swapping cylinders.
Product Changeover
Quickly adjust the end-stop position by up to 10mm to accommodate slightly different product heights on a high-thrust assembly line.
Heavy Clamping Stops
Secure large workpieces with 6136N of force while fine-tuning the clamping travel distance to avoid deforming delicate components.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX60-10 the Right Cylinder?
Choose this 125mm bore when your application demands high thrust—6136N push at 0.5MPa—within a short 50-60mm adjustable travel window. If you need less force, stepping down to a 100mm bore yields 3927N push at 0.5MPa. The rear adjuster screw acts purely as a travel stop for end-position tuning; it does not hold the load without live air. For load-holding requirements without continuous pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model matches standard SAI dimensions. To replicate this exact configuration, specify a 125mm bore, 60mm stroke, 10mm adjustment range, PT tapered ports, SUS420J2 rod material, and no magnet. Because the 60mm stroke is short, side-load risks are minimal, but an external guide is always recommended for heavy radial loads.
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 SAIJ125AX60-10 FAQ
At 0.5MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. At a maximum 1.0MPa, it can deliver up to 1251kgf.
The rear adjuster screw allows you to shorten the 60mm nominal stroke by up to 10mm, creating a 50-60mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
