About the Airtac SAI100 Standard Air Cylinder SAI100BX800
The AirTAC SAI100X800 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and an 800mm stroke. It delivers a robust push force of 5497 N at 0.7 MPa, making it well-suited for moving substantial masses across long linear distances. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting accessory installation.
This specific configuration incorporates a SUS304 stainless steel piston rod (material code B), offering excellent corrosion resistance for harsh or washdown environments. It utilizes PT tapered port threads (G1/2) for reliable pneumatic sealing. Furthermore, the barrel features integrated sensor grooves on both sides, allowing for direct and secure mounting of CMSE or DMSE series magnetic switches if a magnet is later required.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX800 Is Used
Automotive Assembly Line
Provides the heavy thrust required to lift and position large engine blocks or chassis components along extended conveyor systems.
Pallet Handling
Ideal for pushing heavy loaded pallets onto transfer shuttles or indexing them through automated stretch-wrapping stations.
Material Extrusion
Drives large molding or extrusion press doors, utilizing the full 800mm stroke to open wide enough for raw material loading and maintenance access.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX800 the Right Cylinder?
Selecting this 100mm bore model makes sense when 80mm bore cylinders (providing 3518 N push at 0.5 MPa) lack the thrust for your heavy loads, but stepping up to 125mm (8590 N at 0.7 MPa) would be excessive overkill. At an 800mm stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, guide the load externally using linear rails or utilize a fully guided cylinder rather than letting the piston rod absorb lateral stresses.
As an ISO 15552 standard cylinder, this unit is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing for seamless drop-in replacements. It features a G1/2 port, PT thread standard, and supports standard mounting accessories like FA/FB flanges. Note that a plain SAI cylinder relies entirely on live air pressure to maintain its position; if pressure is lost, the load will drop. For fail-safe position holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-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 SAI100 Standard Air Cylinder SAI100BX800 FAQ
The SAI100X800 cylinder generates a push force of 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa. The maximum theoretical force at 1.0 MPa is 801 kgf.
No. The adjustable air cushions only decelerate the piston at stroke ends and do not act as a brake. If you need to hold a load vertically without live air pressure, use the SAIL (air-released lock) variant, the BSAI clamp-lock cylinder, or an external rod lock.
