Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-100
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 375mm 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 SAIJ32BX375-100
The AirTAC SAIJ32X375-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 275 to 375 mm, allowing you to dial back the 375 mm nominal stroke by up to 100 mm during commissioning. It delivers a 402 N pull force at 0.5 MPa, scaling to a 724 N push force at 0.9 MPa. This bore size uses a G1/8 port and features a 12 mm SUS304 stainless steel rod for corrosion resistance.
The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning external solid-state or reed switches will not detect position without modification. The rear adjuster acts purely as a mechanical stop to set the end position; it does not hold the load without live air. For secure load holding without pneumatic pressure, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-100 Is Used
Product Changeovers
Quickly reconfigure the end-of-stroke position for different package lengths on a packaging line without swapping out the entire cylinder assembly.
Machine Setup
Fine-tune the 275 to 375 mm travel window during initial commissioning to perfectly time machine sequencing and avoid mechanical crashes.
Variable End Stops
Adjust the retract distance on the fly to accommodate varying product dimensions moving down a conveyor without halting production.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-100 the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-position tuning without adding external stops. If you need higher force, stepping up to a 40 mm bore increases the 0.5 MPa push force to 628 N. The 100 mm adjustment range is excellent for machines processing varying product sizes. To replace an ISO 15552 cylinder, match the 32 mm bore, 375 mm stroke, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR brackets.
Because the 375 mm stroke is relatively long for a 32 mm rod, it can generate significant side loads if the load is unsupported. Always use an external guide rail to prevent rod binding and premature seal wear.
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 SAIJ32BX375-100 FAQ
At 0.5 MPa, it provides a 402 N push force and a 345 N pull force. At 0.9 MPa, the push force increases to 724 N.
A rear mechanical screw allows you to trim the effective travel back by up to 100 mm, creating a usable 275 to 375 mm stroke window. It functions as a travel stop and does not lock the load without live air pressure.
