About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-40S
The AirTAC SAIJ100X175-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port. By turning the rear screw, you can trim the nominal 175 mm travel back by up to 40 mm, creating a precise 135-175 mm usable positioning window without adding external stops.
This adjustable-stroke design is ideal for fine-tuning end positions during commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions strictly as a travel stop to set deceleration, not as a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-40S Is Used
Product Size Changeovers
Dial in the 135-175 mm travel window during format changes on packaging lines, using the rear screw to instantly match new product dimensions without swapping hardware.
Machine Setup Calibration
Fine-tune the exact end-of-stroke position during initial commissioning, relying on the 3927N push force to securely form or press components.
Variable End-Stop Forming
Adjust the retraction point on the fly for flexible pressing depths, utilizing the SUS304 stainless steel rod for durability in industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-40S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, such as the 3927N push or 3681N pull force available at 0.5 MPa. If your setup needs less force, stepping down to an 80 mm bore yields 2513N push force, whereas moving up to a 125 mm bore provides 6136N. The adjustable 135-175 mm window is perfect for variable end-stop requirements, whereas a fixed SAI cylinder is better for rigid, unchanging positions.
Because this is a 175 mm stroke, it sits below the 300 mm threshold, but the 25 mm rod and M20x1.5 thread still provide excellent rigidity against side loads. For true load-holding without continuous air pressure, this cylinder will not suffice; you should select an AirTAC SAIL or BSAI model instead. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 175 mm stroke, 40 mm adjustment, PT port, and the -S magnet option.
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 SAIJ100 Adjustable Cylinder SAIJ100BX175-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster allows you to shorten the 175 mm nominal stroke by up to 40 mm, creating a usable travel window of 135-175 mm. It acts as a mechanical stop to set the end position and does not lock the load without air pressure.
