Airtac Adjustable Cylinder SAIJ32 SAIJ32X800-75
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X800-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 800mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X800-75
The AirTAC SAIJ32X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 725-800 mm usable travel window, allowing you to dial back the 800 mm nominal stroke by up to 75 mm during commissioning. In the 32 mm bore class, it delivers 563 N of push force at 0.7 MPa.
This model uses a 12 mm carbon steel piston rod with an M10x1.25 thread, paired with PT (tapered) port threading and a G1/8 air supply port. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific SKU is not magnetized. The rear adjuster acts purely as a travel stop, meaning the cylinder cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X800-75 Is Used
Machine Changeover
Fine-tune the 725-800 mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
Variable End Stops
Set precise retraction positions for parts exiting a long conveyor line, adjusting the 75 mm window to accommodate varying package lengths.
Commissioning Calibration
Dial in the exact end-of-stroke position during initial machine setup to absorb mechanical tolerance and achieve precise 32 mm bore positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X800-75 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your machine setup requires variable end stops or product changeover without swapping the entire actuator. If your application needs higher thrust, stepping up to the 40 mm bore provides 879 N of push force at 0.7 MPa. For load-holding without live air, consider the SAIL (pneumatic lock) or BSAI (clamp-lock) series instead, as the SAIJ adjuster is not a brake.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, 75 mm adjustment range, PT port thread, G1/8 port size, and standard carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 800 mm stroke is long and the 12 mm rod is relatively slender, an external guide is recommended to prevent side-load damage.

- ✓ 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 SAIJ32X800-75 FAQ
This 32 mm bore cylinder provides 402 N of push force and 345 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 800 mm nominal stroke by up to 75 mm, creating a 725-800 mm usable travel window. It does not lock the load without live air.
