About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20
The AirTAC SAIJ63X130-20 is a double-acting ISO 15552 profile cylinder with a rear mechanical adjuster, allowing you to dial back the 130 mm nominal stroke by up to 20 mm. This creates a precise 110-130 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the hardware or adding external stops. It delivers 1559 N of pull force and 2182 N of push force at 0.7 MPa, fitting robustly into mid-range pneumatic setups.
This SKU features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this specific configuration omits the internal magnet. Remember that the rear adjuster acts strictly as a travel stop for deceleration, not a lock, so it will not hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20 Is Used
End-Stop Calibration
Dial in the exact 110 to 130 mm travel distance during machine commissioning to accommodate varying material thicknesses without changing out the cylinder.
Product Changeover
Quickly adjust the rear stopper on the line when switching to a new product size, reducing downtime and eliminating the need for external mechanical stops.
Assembly Positioning
Push or pull loads up to 2182 N at 0.7 MPa to move components into place, relying on the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20 the Right Cylinder?
Choose this 63 mm bore cylinder when your application requires 1559 N pull force at 0.5 MPa, sitting neatly between the 50 mm bore (825 N pull) and the larger 80 mm bore (2268 N pull). The adjustable 110-130 mm travel window is ideal for machine setups requiring variable end-stops or product changeovers, providing more flexibility than a fixed-stroke SAI cylinder. If your process demands true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as this rear adjuster only functions as a stroke stop.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 130 mm nominal stroke, 20 mm adjustment range, PT G3/8 port, and the desired mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load stress is moderate, but you should still ensure proper guiding for any heavy loads.

- ✓ 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 SAIJ63AX130-20 FAQ
The rear adjuster screw lets you shorten the effective travel from the 130 mm nominal stroke down to 110 mm, giving a 20 mm tuning window. This stopper sets the end position and aids deceleration, but it does not lock the load without live air pressure.
At 0.5 MPa, it provides 1559 N of pull force and 2182 N of push force at 0.7 MPa. It operates at speeds between 30 and 800 mm/s.
