About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30S
The AirTAC SAIJ32X375-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 345 to 375 mm, letting you dial in the exact return point at commissioning without adding external stops. In its standard 0.5 MPa operating state, this 32 mm bore generates 402 N of push force and 345 N of pull force.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and because this is a -S model, it contains a magnet ready for AirTAC CMSE reed and DMSE electronic solid-state switches. The PT tapered port is G1/8, and the cylinder operates at speeds of 30 to 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30S Is Used
Machine Changeover
Quickly adjust the retract end-stop within the 345-375 mm window when switching product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the exact return position during commissioning to align tooling perfectly, using the rear screw rather than adding external shims.
Test Fixture Setup
Dial in the precise retraction distance for repetitive material testing routines where the exact return point varies by sample thickness.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise retract positioning that a fixed-stroke SAI cannot provide. If your process demands more thrust, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa, but the 32 mm bore is ideal for lighter duty. To replace an ISO 15552 cylinder, match the 32 mm bore, 375 mm stroke, 30 mm adjustment, PT G1/8 port, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Because the nominal stroke is 375 mm, the 12 mm rod and M10x1.25 thread will experience greater leverage forces on unsupported loads; an external guide is recommended to prevent side-load damage. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series instead.
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 SAIJ32AX375-30S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 345 to 375 mm, allowing you to set the exact retract end-position without swapping cylinders or adding external stops.
At a standard 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563 N.
