About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-10
The AirTAC SAIJ100X190-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 180-190mm usable travel window, letting you dial back the 190mm nominal stroke by up to 10mm during machine setup. In the 100mm bore class, it generates 3927N of push force and 3681N of pull force at 0.5 MPa, scaling up to 7068N push at 0.9 MPa.
This unit uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries PT (tapered) G1/2 port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a travel stop to set end positions and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-10 Is Used
Machine Changeover
Dial in the exact 180-190mm end-stop during product size changes without replacing the entire cylinder or adding external mechanical stops.
Commissioning Tuning
Fine-tune the final retract position by up to 10mm during initial machine setup to align tooling perfectly under load.
Assembly Pressing
Leverage the 3927N push force at 0.5 MPa for pressing operations while retaining the ability to trim the stroke for different assembly heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-10 the Right Cylinder?
Choose this 100mm bore adjustable-stroke cylinder when your application requires exact end-position tuning at commissioning or during product changeovers, avoiding the need to swap cylinders or bolt on external stoppers. If your thrust requirements are lower, stepping down to an 80mm bore yields 2513N push force at 0.5 MPa. Because the 190mm stroke is relatively short, side-load stress on the 25mm rod thread is minimal, though longer unsupported strokes will still need an external guide.
For load-holding without continuous air pressure, note that the SAIJ rear adjuster and air cushions function only as travel stops, not as a brake. You would need to specify an SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead. To match this ISO 15552 interchangeable profile cylinder, confirm the 100mm bore, 190mm stroke, 10mm adjustment, PT G1/2 port, and your required mounting option from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX190-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If you increase the pressure to 0.9 MPa, the push force scales up to 7068N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 190mm nominal stroke by up to 10mm, providing a 180-190mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
