Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 190mm stroke, G1/2 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 SAIJ100 Adjustable Cylinder SAIJ100BX190-30S
The AirTAC SAIJ100X190-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 160-190 mm usable travel window by allowing you to dial back the 190 mm nominal stroke by up to 30 mm. In the 100 mm bore class, it generates 5497 N of push force at 0.7 MPa, making it well-suited for heavy positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30S Is Used
Machine Changeover Setup
Dial in the exact end-stop position during product size transitions on a packaging line without physically swapping cylinders or adding external stopper blocks.
Commissioning Fine-Tuning
Trim the travel window down by 30 mm to perfectly time heavy machinery strokes during initial setup, preventing mechanical crashes before they happen.
Heavy Payload Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or fixtures, relying on the built-in rear stopper to set the precise retraction depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust (5497 N at 0.7 MPa) alongside precise end-position tuning. If your force requirements are lower, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, saving space and air consumption. The 30 mm adjustable window is ideal for machine setups requiring variable end-stops during product changeovers. To match this ISO 15552 replacement exactly, verify the 190 mm stroke, 30 mm adjustment, PT port threads, SUS304 rod, and the -S magnet for CMSE or DMSE sensors. Since the stroke is under 300 mm, side-load stress is moderate, but the robust 25 mm rod and M20x1.5 thread handle standard loads effectively.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX190-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 160-190 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
At a standard 0.7 MPa operating pressure, the SAIJ100X190-30-S generates 5497 N of push force and 3681 N of pull force. It can deliver a maximum push force of 7068 N at 0.9 MPa.
