About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-10
The AirTAC SAIJ32X300-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 290 to 300mm, letting you dial back the nominal stroke by up to 10mm during commissioning. The PT tapered port threads and SUS420J2 stainless steel rod material offer solid corrosion resistance for general pneumatic setups.
Because the 300mm stroke is relatively long for a 32mm bore, the 12mm rod and M10x1.25 thread should be guided externally to prevent side-loading damage. The rear adjuster acts strictly as a travel stop to fine-tune the end position, so it will not hold the load without live air pressure. For true load-holding, you would need an external rod lock or a SAIL series cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-10 Is Used
Machine Setup Tuning
Dial in the exact 290-300mm retract stop during machine commissioning to perfect end-position accuracy without physically remounting the cylinder.
Product Changeover
Quickly adjust the effective stroke by up to 10mm on a packaging line when switching to a slightly different product size or format.
Conveyor End Stops
Fine-tune the stopping position of light-duty conveyor payloads using the rear screw, avoiding the need to install and shim separate external hard stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-10 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning without swapping out the entire cylinder or adding bulky external stops. If your application requires higher force, stepping up to the 40mm bore increases the 0.5 MPa push force to 628N. If you need to hold a load mechanically without continuous air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead of relying on the SAIJ adjuster.
When replacing an ISO 15552 cylinder, match the 32mm bore, 300mm nominal stroke, 10mm adjustment range, PT port threads, and required mounting interface. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 300mm, ensure an external guide supports the load to protect the rod from side-load stress.
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 SAIJ32AX300-10 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10mm, creating a 290-300mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
