About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-10
The AirTAC SAIJ63X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 145-155 mm usable travel window, allowing you to dial back the nominal 155 mm stroke by up to 10 mm during commissioning without adding external stops. It delivers a robust 2182 N push force at 0.7 MPa, making it suitable for medium-duty handling.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-10 Is Used
End-Stop Tuning
Dial in the exact 145-155 mm retract position during machine commissioning without swapping cylinders or machining external stop blocks.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate slight variations in incoming product size on a packaging line.
Medium-Force Positioning
Leverage the 2182 N push force at 0.7 MPa to push parts into a fixture while fine-tuning the final resting position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-10 the Right Cylinder?
Select this 63 mm bore cylinder when your application requires 2182 N of push force at 0.7 MPa and on-the-fly end-position tuning. If your setup needs less force, stepping down to a 50 mm bore yields 1374 N at 0.7 MPa. Conversely, an 80 mm bore provides 3518 N for heavier loads. The 10 mm adjustment range is ideal for product changeovers where a fixed SAI cylinder would require physical shimming.
When matching this for an ISO 15552 replacement, verify the 63 mm bore, 155 mm stroke, 10 mm adjuster, PT G3/8 port, and the specific mounting accessory. Since the stroke is 155 mm, ensure adequate guidance to prevent excessive side-load on the rod. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-10 FAQ
At a standard 0.7 MPa operating pressure, this 63 mm bore cylinder generates 2182 N of push force and 1402 N of pull force. It can deliver up to 318 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw allows you to shorten the effective travel from the 155 mm nominal stroke down to 145 mm. This creates a 145-155 mm usable window for fine-tuning the end position at commissioning, but it functions only as a stop and does not lock the load without live air.
