About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30S
The AirTAC SAIJ32X175-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 145-175 mm usable travel window, letting you trim up to 30 mm from the 175 mm nominal stroke during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks without needing external stops.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Equipped with a magnet, it supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30S Is Used
Machine Setup Tuning
Dial in the exact 145-175 mm end position during initial machine commissioning without swapping cylinders or adding bulky external stopper blocks.
Product Changeover
Quickly adjust the stroke end-stop by up to 30 mm to accommodate slight variations in incoming product sizes on a packaging line.
Light Assembly Positioning
Apply up to 402 N of push force at 0.5 MPa to move and position light components, using the rear screw to fine-tune the final touch point.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30S the Right Cylinder?
Select this 32 mm bore when an application requires 402 N push force at 0.5 MPa and on-the-fly end-position tuning. If your setup needs higher thrust, stepping up to the 40 mm bore yields 628 N. Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when you need a variable end-stop for product changeovers. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider an SAIL or BSAI cylinder.
For this 175 mm stroke, which is below the 300 mm side-load threshold, the 12 mm rod and M10x1.25 thread handle standard guiding tasks adequately. To replace an ISO 15552 cylinder, match the 32 mm bore, 175 mm stroke, 30 mm adjustment, PT G1/8 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX175-30S FAQ
An external adjusting screw at the rear acts as a stopper, allowing you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 145-175 mm. The adjuster only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
