About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30
The AirTAC SAIJ32X425-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 395 to 425 mm, letting you dial back the nominal 425 mm stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is crafted from SUS304 stainless steel for superior corrosion resistance.
The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it cannot hold a load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL or BSAI series. This model uses a PT G1/8 port and omits the FB, CA, CB, and CR mounting interfaces, retaining the Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30 Is Used
Machine Changeover
Fine-tune the retract end position by up to 30 mm during product size changes without replacing the entire cylinder or adding external physical stops.
Variable End Stops
Dial in the exact 395 to 425 mm travel distance required for delicate positioning tasks, ensuring perfect alignment during commissioning.
Light-Duty Positioning
Utilize the 402 N push force at 0.5 MPa for moving light components along an assembly line, relying on the SUS304 rod for corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without adding external stops or swapping cylinders on product changeovers. If your process needs less force, stepping down is not an option below 32 mm, but stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable 395-425 mm window is perfect for machines handling varying part sizes.
Because the 425 mm stroke is relatively long for a 32 mm rod, an external guide is highly recommended to prevent excessive side-loading and premature seal wear. This cylinder is dimensionally interchangeable per ISO 15552, uses a PT G1/8 port, and lacks a magnet (-S not specified). The rear stopper and air cushions manage deceleration but do not function as a lock.
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 SAIJ32BX425-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 425 mm down to a minimum of 395 mm. It sets the retract end position but does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
