About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-100
The AirTAC SAIJ50X260-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 982N of push force at 0.5 MPa and provides a usable travel window of 160-260mm, letting you dial back the nominal 260mm stroke by up to 100mm during commissioning. This built-in adjustability eliminates the need to swap cylinders or bolt on external stoppers when fine-tuning end positions.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet, meaning position sensing via CMSE or DMSE switches is not supported without adding the -S option.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-100 Is Used
Variable End-Stop Tuning
Perfect for assembly stations requiring precise end-position tuning across a 160-260mm range without changing hardware.
Product Size Changeover
Quickly adapt machinery to different product lengths by dialing the stroke back up to 100mm during line format changes.
Commissioning Calibration
Fine-tune the retract stroke during machine setup to prevent mechanical interference, avoiding external stopper hardware.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-100 the Right Cylinder?
Choose this 50mm bore cylinder when you need 982N of push thrust at 0.5 MPa with extensive on-machine adjustability. If your application requires less force, stepping down to a 40mm bore yields 628N; if you need more clamping power, stepping up to a 63mm bore provides 1559N. The 100mm adjustment range is ideal for product-size changeovers on a line, offering far more flexibility than a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, confirm the 260mm stroke, 100mm adjuster, PT port thread, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because the nominal stroke is 260mm, ensure adequate support to prevent rod sag and side-load wear, utilizing an external guide if the load is unsupported. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ50 Adjustable Cylinder SAIJ50AX260-100 FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 260mm down to 160mm, creating a 100mm adjustable window. It acts as a mechanical stop to fine-tune the retract end position without needing a different cylinder.
