Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X130-20S
The AirTAC Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X130-20S 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 SAIJ63X130-20S
The AirTAC SAIJ63X130-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 110-130 mm usable travel window, allowing you to dial back the nominal 130 mm stroke by up to 20 mm during commissioning without adding external stops. In the 63 mm bore class, it delivers 1559 N of pull force at 0.5 MPa and 2182 N of push force at 0.7 MPa, making it well-suited for medium-duty positioning tasks.
This model features a standard carbon steel piston rod with an M16x1.5 thread and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the included -S magnet enables position detection using AirTAC CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X130-20S Is Used
Machine Changeover
Dial in the 110-130 mm stroke window on the fly during product size changeovers without swapping out the entire cylinder or reworking the fixture.
End-Stop Calibration
Fine-tune the retract end position during commissioning to absorb mechanical tolerances and achieve precise seating of medium-force components.
Variable Position Diverter
Adjust the stroke length to shift the contact point for a diverter gate on a packaging line, accommodating different package widths on the fly.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X130-20S the Right Cylinder?
Select this 63 mm bore adjustable cylinder when a process requires precise end-position tuning over a 110-130 mm window, rather than committing to a fixed-stroke SAI variant. If your application needs less force, stepping down to a 50 mm bore yields 825 N of pull force at 0.5 MPa. Conversely, an 80 mm bore provides 2268 N of pull force for heavier loads. Because the SAIJ rear adjuster is a travel stop and not a lock, any requirement for true load-holding without continuous air pressure should point you toward the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 130 mm nominal stroke, 20 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets to streamline the profile design.
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 SAIJ63X130-20S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of pull force and 1402 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw lets you mechanically shorten the effective travel from 130 mm down to 110 mm. This allows precise end-position tuning at commissioning without replacing the cylinder, though the adjuster only acts as a stop and does not lock the load.
