Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-50
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 130mm 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 SAIJ63AX130-50
The AirTAC SAIJ63X130-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5MPa. By turning the external stopper at the rear, you can shorten the effective travel from its 130mm nominal length down to 80mm, creating an 80-130mm usable window. This allows precise end-position tuning at commissioning without swapping the barrel or bolting on external stops.
This unit features a SUS420J2 stainless steel piston rod (option A) for improved corrosion resistance over standard carbon steel. It uses PT tapered port threads (G3/8) and lacks a magnet, meaning electronic DMSE or reed CMSE position sensing cannot be added to this specific configuration. The rear adjuster acts purely as a mechanical travel stop to decelerate the load, not as a locking mechanism.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-50 Is Used
Machine Setup & Changeover
Dial in the exact 80-130mm travel window during product changeovers without physically replacing the cylinder or adding external shims.
Variable End-Stop Positioning
Use the 50mm rear mechanical stopper to fine-tune the retract end-position precisely during initial machine commissioning.
Corrosion-Resistant Actuation
Leverage the SUS420J2 stainless steel rod in standard industrial environments where minor moisture or contamination is present.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-50 the Right Cylinder?
Choose this 63mm bore when a 50mm bore (providing 982N push at 0.5MPa) lacks sufficient thrust, but an 80mm bore (delivering 2513N) would be oversized. The 50mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing operators to dial in the exact 80-130mm travel window on the fly. For applications that must hold a load in place without live air pressure, note that this adjuster is only a stop; you should look at the SAIL or BSAI locking cylinder series instead. To match this exact configuration for an ISO 15552 replacement, specify a 63mm bore, 130mm stroke, 50mm adjustment, PT G3/8 ports, SUS420J2 rod, no magnet, and a mounting style from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ63AX130-50 FAQ
It features a rear external stopper that allows you to mechanically shorten the 130mm nominal stroke by up to 50mm, providing an adjustable 80-130mm travel window. The adjuster acts as a stop to set the end position and does not lock the load without air pressure.
This 63mm bore double-acting cylinder provides 1559N of push force and 1402N of pull force at 0.5MPa. At 0.7MPa, the push force increases to 2182N.
