About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-100
The AirTAC SAIJ32X175-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 175 mm stroke that can be dialed back by up to 100 mm, creating a highly flexible 75-175 mm usable travel window for exact end-position tuning during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is later required. The rear adjuster acts purely as a travel stop to decelerate the piston, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-100 Is Used
Product Size Changeovers
Dial in the exact 75 to 175 mm stroke required for different product lengths on a packaging line without changing the cylinder or adding external stops.
Machine Commissioning
Fine-tune the retract end-position during initial setup to perfectly align tooling, absorbing mechanical tolerances directly via the rear adjuster.
Variable End-Stop Positioning
Provide a customizable hard stop for delicate operations, allowing operators to modify the effective travel window on the fly for diverse component handling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-100 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires frequent product-size changeovers or variable end-stops without swapping out physical hardware. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, whereas dropping below 32 mm is not standard for this ISO 15552 series. The generous 100 mm adjustment range on a 175 mm stroke provides immense setup flexibility, acting as an external stop built directly into the rear cap.
To match this exact configuration for an ISO 15552 replacement, specify a 32 mm bore, 175 mm stroke, 100 mm adjustment range, PT port thread, and SUS304 stainless steel rod. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the 175 mm stroke is relatively long for this smaller bore, ensure adequate external guiding to prevent excessive side-loading on the rod. If your process requires true load-holding without live air, consider the SAIL or BSAI locking cylinder variants instead.

- ✓ 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 SAIJ32BX175-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 175 mm down to as little as 75 mm, creating a 75-175 mm usable window. This adjuster functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
