About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-30
The AirTAC SAIJ32X375-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 345-375 mm usable travel window, allowing you to dial back the 375 mm nominal stroke by up to 30 mm during machine commissioning without adding external stops. It delivers 563 N of push force at 0.7 MPa.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. The rear adjuster acts strictly as a travel stop to fine-tune end positions, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-30 Is Used
Machine Commissioning
Fine-tune the 345-375 mm travel window during setup to hit exact end positions without swapping cylinders.
Product Changeover
Quickly adjust the retract stop for varying product sizes on a single line, saving retooling time.
Variable End Stops
Dial in the exact 30 mm trim on a 375 mm stroke for precision positioning tasks in automated machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 563 N of push force at 0.7 MPa with a specific 345-375 mm stroke window. If you need less force, step down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 879 N of push force at 0.7 MPa. The adjustable stroke is ideal for product changeovers where exact end-position tuning is required, unlike a fixed-stroke SAI cylinder.
For replacement, match the 32 mm bore, 375 mm stroke, 30 mm adjustment, PT port, and standard rod without a magnet. Because the stroke is 375 mm, the 12 mm rod and M10x1.25 thread may experience side loads on long extensions; use an external guide to prevent rod bending. For load-holding without live air, select a SAIL or BSAI cylinder 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 SAIJ32BX375-30 FAQ
The rear adjuster screw lets you shorten the 375 mm nominal stroke by up to 30 mm, providing a 345-375 mm travel window. It acts as a mechanical stop for end-position tuning and is not a lock.
At 0.7 MPa operating pressure, the SAIJ32X375-30 provides 563 N of push force and 345 N of pull force. At 1.0 MPa, the maximum push force is 402 N.
