About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-20S
The AirTAC SAIJ32X130-20-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 trim the 130 mm nominal stroke by up to 20 mm during commissioning. Delivering 563 N of push force at 0.7 MPa, it handles light-duty positioning with precision.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 fitting size for this 32 mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-20S Is Used
Machine Setup Tuning
Fine-tune the 110-130 mm travel window during initial commissioning to dial in exact contact points without machining new hard stops.
Product Changeover
Quickly adjust the retract end-position by up to 20 mm on packaging lines when switching between slightly different product sizes.
Light Assembly Positioning
Leverage the 563 N push force and SUS304 rod for precise, corrosion-resistant component placement in compact assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-20S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires exact end-position tuning without adding external stops. If your setup needs more force, stepping up to the 40 mm bore yields 879 N push at 0.7 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL series. To replace an ISO 15552 cylinder, match the 130 mm stroke, 20 mm adjustment, PT port, and -S magnet.
Because the 130 mm stroke is relatively short, side-loading is less severe than on longer strokes, but the 12 mm rod still requires external guidance for heavy lateral loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX130-20S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm, providing a usable travel window of 110-130 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.7 MPa operating pressure, the SAIJ32X130-20-S generates 563 N of push force and 484 N of pull force. It operates at speeds between 30 and 800 mm/s.
