Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-50
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 180mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-50
The AirTAC SAIJ63X180-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 180 mm travel by up to 50 mm. This creates a precise 130-180 mm usable stroke window, allowing exact end-position tuning at commissioning without swapping hardware. It delivers 1559 N of pull force at 0.5 MPa, scaling up to 2805 N at 0.9 MPa.
Built with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this extruded aluminum profile cylinder handles speeds of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to set the travel end alongside the standard air cushions; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-50 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 130-180 mm window during machine setup, eliminating the need for custom spacer blocks.
Product Size Changeover
Quickly adapt a packaging line to different carton depths by rotating the rear adjuster screw to shift the end-of-stroke position.
Clamp Force Calibration
Fine-tune the clamping reach on a 63 mm bore actuator delivering up to 2805 N of push force at 0.9 MPa without changing the cylinder body.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-50 the Right Cylinder?
Select this 63 mm bore cylinder when an application requires intermediate force—stepping down to a 50 mm bore yields 825 N pull at 0.5 MPa, while stepping up to an 80 mm bore provides 2268 N. The generous 50 mm adjustment range is ideal for product-size changeovers on a line, providing variable end-stops without adding external stops. To replace an ISO 15552 cylinder, match the 63 mm bore, 180 mm nominal stroke, 50 mm adjuster, G3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since this is a non-magnet version, add an -S suffix if CMSE reed or DMSE electronic sensors are needed.

- ✓ 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 SAIJ63AX180-50 FAQ
The rear adjuster screw allows you to mechanically shorten the 180 mm stroke by up to 50 mm, providing a usable travel range of 130-180 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
At 0.5 MPa it provides 1559 N pull and 2182 N push. At the maximum operating pressure of 1.0 MPa, it delivers a peak push force of 318 kgf.
