About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10S
The AirTAC SAIJ32X400-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 400 mm nominal stroke that can be fine-tuned back by up to 10 mm, creating a precise 390-400 mm usable travel window. This bore size delivers 402 N of push force at 0.5 MPa and includes a SUS304 stainless steel rod for superior corrosion resistance.
The barrel is an extruded aluminum profile with sensor grooves on both sides, and the included magnet supports CMSE reed and DMSE solid-state switches. It uses PT tapered ports sized at G1/8. Because the adjuster acts purely as a mechanical stop at the retract end, it does not lock the load without live air pressure; for load-holding requirements, consider an external rod lock or AirTAC SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10S Is Used
Machine Setup Calibration
Dial in the exact 390-400 mm end position during commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover Lines
Quickly adjust the retract end-stop by up to 10 mm to accommodate slight variations in product sizes on the same production line.
Light-Force Positioning
Move light payloads with 402 N of push force while relying on the stainless SUS304 rod for corrosion resistance in varied environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10S the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N of thrust at 0.5 MPa and a built-in end-stop for commissioning flexibility. If your application requires less force, there is no smaller standard SAIJ bore, but stepping up to a 40 mm bore provides 628 N of push force. The 10 mm adjustment range is ideal for dialing in exact end positions during machine setup without adding external stopper blocks.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 400 mm stroke, 10 mm adjustment, PT G1/8 ports, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this stroke is 400 mm, the 12 mm diameter rod is highly susceptible to side-loading; always use an external guide rail to prevent premature seal wear and rod bending.

- ✓ 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 SAIJ32BX400-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 400 mm nominal stroke by up to 10 mm, providing a usable travel window of 390-400 mm. It only sets the travel end and does not hold the load without live air pressure.
