About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-30S
The AirTAC SAIJ63X180-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 63 mm bore delivering 1559 N pull force at 0.5 MPa, paired with a 180 mm nominal stroke that can be dialed back by up to 30 mm. This creates a precise 150-180 mm usable travel window, allowing you to fine-tune the retract end position at commissioning without swapping out the entire unit.
Built with an SUS420J2 stainless steel rod (code A) and PT tapered ports, this model includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides, and the adjustable stopper acts purely as a travel end limiter, not a load-holding lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-30S Is Used
Machine Changeover
Dial in the 150-180 mm retract position during product size changes without adding external mechanical stops to the fixture.
End-Position Tuning
Fine-tune the final retract distance by up to 30 mm during setup to perfect the seating of parts on an automated line.
Assembly Pressing
Leverage 2182 N of push force at 0.7 MPa to seat components, using the adjuster to limit travel and prevent over-travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-30S the Right Cylinder?
Choose this 63 mm bore when you need 1559 N pull or 2182 N push at 0.7 MPa; step down to a 50 mm bore (825 N pull at 0.5 MPa) for lighter loads, or up to an 80 mm bore (2268 N pull) for heavier duty. An adjustable stroke is ideal for product changeovers on a line, letting you shift the end-stop on the fly instead of bolting on external stops or buying a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, verify the 180 mm stroke, 30 mm adjuster, PT G3/8 port, and the -S magnet requirement.
Because the nominal stroke is 180 mm, side-load stress is moderate, but the 20 mm rod diameter handles it well; always guide the load externally for optimal bearing life. Remember that the rear adjuster only sets the travel end and does not hold the load without live air—if you need true load-holding without pressure, 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-30S FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull. At 0.7 MPa the push force increases to 2182 N, with a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 30 mm, creating a 150-180 mm usable travel window. It functions as a mechanical stop and does not lock the load without air pressure.
