About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX45-10S
The AirTAC SAIJ50X45-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 45mm stroke that can be dialed back by up to 10mm, creating a precise 35-45mm usable travel window for fine-tuning end positions at commissioning. Delivering 982N of push force at 0.5MPa, it handles moderate actuation tasks with ease.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a built-in magnet (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE solid-state switches. Fluid supply is via PT tapered G1/4 ports, and the adjustable stopper functions purely as a travel end-limit, not a load-holding lock.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX45-10S Is Used
Machine Changeover
Dial in the 35-45mm travel window during product size changes on a packaging line without replacing the cylinder or adding external shims.
End-Stop Calibration
Fine-tune the retract end-position at commissioning to ensure precise mechanical alignment, using the rear screw rather than adjusting the entire fixture.
Corrosive Assembly Lines
Leverage the SUS420J2 stainless steel rod in environments with moisture or light chemicals, maintaining reliable 982N thrust over a variable stroke.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX45-10S the Right Cylinder?
Choose this 50mm bore when an application requires 982N push force at 0.5MPa and on-the-fly stroke trimming without swapping cylinders or adding external stops. If your machine needs less force, the 40mm bore offers 628N; if you need more, the 63mm bore provides 1559N. The adjustable rear screw is ideal for product changeovers, but remember it only sets the travel end—it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.
This SAIJ50X45-10-S is dimensionally interchangeable per ISO 15552 standards. To match this exact configuration: specify a 50mm bore, 45mm stroke, 10mm adjustment range, PT port thread, and the -S magnet option. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX45-10S FAQ
At 0.5MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At the maximum 1.0MPa pressure, it delivers up to 200kgf of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 35-45mm from the nominal 45mm stroke, letting you set the exact end-position without moving the cylinder mount. The adjuster acts as a stop and does not lock the load without live air.
