About the Airtac SAI100 Standard Air Cylinder SAI100BX450
The AirTAC SAI100X450 is a double-acting ISO 15552 profile cylinder engineered to deliver 3927 N of push force at 0.5 MPa. With a 450 mm stroke, it is purpose-built for heavy-duty automation requiring substantial linear travel. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that is dimensionally interchangeable per ISO 15552 standards.
This specific configuration features a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning it operates without electronic position sensing unless externally retrofitted.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX450 Is Used
Heavy Material Handling
Drives robust pallet transfers and heavy-gauge conveyor indexing systems where a 450mm stroke and high kinetic energy are required.
Automotive Component Pressing
Applies steady 3927N clamping or pressing forces to automotive sub-components during automated assembly operations.
Large Pallet Positioning
Positions and sorts oversized pallets in high-throughput distribution centers, utilizing the 100mm bore capacity.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX450 the Right Cylinder?
Stepping down to the 80mm bore neighbor reduces your 0.5 MPa push force to 2513 N, while moving up to the 125mm bore increases it to 6136 N. For a 450 mm stroke, the unsupported rod length is significant; side loads will cause rod-bearing bending and premature wear. Employ an external guide rail or select a guided cylinder to manage off-center loads.
This model features a G1/2 port and accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Because it is a standard double-acting cylinder, it does not hold position upon loss of air pressure; if your application requires fail-safe holding, consider the SAIL variant with an air-released 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.
