About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30
The AirTAC SAIJ32X175-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a 0.7 MPa push force of 563 N and utilizes a PT G1/8 port. The integrated adjuster allows you to trim the effective travel back by up to 30 mm, creating a precise 145-175 mm usable stroke window for fine-tuning at commissioning.
This variant uses an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to drop in CMSE reed or DMSE electronic switches. The rear screw acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30 Is Used
Machine Changeover
Dial in the 145-175 mm stroke window during product size changes without physically replacing the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to achieve exact alignment, using the 30 mm rear adjuster to compensate for mechanical tolerances.
Light Assembly Push
Utilize the 563 N push force at 0.7 MPa for precise pressing or light assembly tasks where over-travel must be dialed out.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-30 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 563 N of push force at 0.7 MPa. If your setup demands less force, stepping down is not an option in the standard SAIJ range, but stepping up to a 40 mm bore provides 879 N. The adjustable 145-175 mm window is ideal for product changeovers, allowing you to shift the end position without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 175 mm nominal stroke, PT G1/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the 175 mm stroke is relatively short, side-load stress on the 12 mm rod is minimal, though an external guide is still recommended for heavy lateral loads.
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 Adjustable Cylinder SAIJ32 SAIJ32AX175-30 FAQ
The rear adjuster acts as an external stopper that shortens the effective travel by up to 30 mm. This gives the 175 mm nominal stroke a usable window of 145-175 mm, allowing you to set the exact retract position without changing the cylinder.
At a standard 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
