About the Airtac SAIJ40 Adjustable Cylinder SAIJ40X175-10
The AirTAC SAIJ40X175-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 175 mm stroke that can be fine-tuned down by up to 10 mm, giving you a precise 165-175 mm usable travel window during machine commissioning. Delivering 628 N of push force at 0.5 MPa, it fits mid-range automation tasks perfectly.
This extruded aluminum profile cylinder features a standard carbon steel piston rod and a PT tapered port thread. It includes sensor grooves on both sides for flexible switch mounting, though a magnet (-S) is required to use CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not lock the load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40X175-10 Is Used
End-Stop Calibration
Dial in the exact 165-175 mm travel distance during machine setup to perfect component seating without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by a few millimeters to accommodate slightly different product sizes on the same line.
Assembly Positioning
Use the 628 N thrust at 0.5 MPa to press parts accurately, relying on the fine-tune screw to prevent overtravel.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40X175-10 the Right Cylinder?
Select this 40 mm bore when you need 628 N push force at 0.5 MPa, stepping up from a 32 mm bore (402 N) if your load demands more thrust, or down from a 50 mm bore (982 N) to save space. The 10 mm adjustment range is ideal for applications requiring exact end-position calibration without adding external stops. For holding a load without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking device. To match this ISO 15552 cylinder, confirm the 175 mm stroke, 10 mm adjuster, PT port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ40 Adjustable Cylinder SAIJ40X175-10 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 165-175 mm travel window. It functions as a mechanical stop for tuning the end position and requires live air to hold the load.
