About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-10S
The AirTAC SAIJ63X180-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 170-180 mm usable travel window, allowing you to dial back the 180 mm nominal stroke by up to 10 mm during commissioning. This bore size delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for mid-range automation tasks.
This variant features an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster acts purely as a travel stop to fine-tune the end position without needing external stops.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-10S Is Used
End-Position Tuning
Dial in the exact 170-180 mm travel window during machine commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm on packaging lines when handling slightly different product sizes.
Mid-Range Assembly
Leverage 1559 N of push force at 0.5 MPa for precision pressing and clamping tasks requiring repeatable end-of-stroke positioning.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-10S the Right Cylinder?
Choose this 63 mm bore when you need 1559 N of push force at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N. The 10 mm adjustable range is ideal for applications requiring exact end-position tuning during machine setup or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. The PT tapered port threads ensure a tight pneumatic connection.
Because the 180 mm stroke is under the 300 mm threshold, standard mounting is generally fine, but always support side loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, use an 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-10S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It can deliver up to 318 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the effective travel from the 180 mm nominal stroke down to 170 mm. This creates a 170-180 mm usable window for fine-tuning the retract end position at commissioning without replacing the cylinder.
