About the Airtac SAI32 Standard Cylinder SAI32BX550
The AirTAC SAI32X550 is a double-acting ISO 15552 profile cylinder engineered for applications requiring a 550 mm stroke, which is a non-standard made-to-order length exceeding the 500 mm standard limit for this 32 mm bore. It delivers a push force of 563 N at 0.7 MPa, making it suitable for moderate load positioning over extended distances.
This unit features a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for flexible CMSE or DMSE switch mounting when a magnet is specified.

Where the Airtac SAI32 Standard Cylinder SAI32BX550 Is Used
Extended Transfer
Pushes products between distant processing stations on a conveyor line over a 550 mm gap.
Vertical Lift Gate
Actuates a lightweight access gate or safety barrier where a long vertical throw is necessary.
Long-Reach Sorting
Deflects parts on a sorting conveyor over a wide physical distance using moderate 563 N force.
Is the Airtac SAI32 Standard Cylinder SAI32BX550 the Right Cylinder?
Because this 550 mm stroke exceeds the 500 mm standard maximum for the 32 mm bore, it is produced as a special order. When specifying this model, consider stepping up to a 40 mm bore (which provides 879 N push force at 0.7 MPa and supports standard strokes up to 1200 mm) if your application requires greater rod rigidity or higher thrust.
At 550 mm of extension, the unsupported piston rod is highly susceptible to bending under side loads; utilize an external guide rail or a guided cylinder to prevent rod-bearing damage. This cylinder does not hold position if air pressure is lost, so integrate a pilot-operated check valve or an external rod lock if fall-prevention is required. It serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, matching the 32 mm bore, G1/8 port, and standard mounting accessories like FA flanges.
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 SAI32 Standard Cylinder SAI32BX550 FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder provides a push force of 563 N and a pull force of 483 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
Yes, the SAI32X550 is dimensionally interchangeable per ISO 15552. It shares the same mounting interface, 12 mm rod, and G1/8 port as other standard 32 mm bore profile cylinders, allowing direct replacement.
