About the Airtac SAI100 Standard Air Cylinder SAI100BX650S
The AirTAC SAI100X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, it is designed to drive substantial loads across a generous 650 mm stroke. The extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into existing ISO 15552 mounting interfaces.
Configured specifically for harsh or washdown environments, this unit features a SUS304 stainless steel piston rod (material code B) and includes a standard magnet (-S) for non-contact position sensing. The integrated magnetic switches ride smoothly in the dual sensor grooves machined into the barrel, accepting CMSE and DMSE series sensors for precise end-of-stroke detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX650S Is Used
Automotive Body Welding
Handles heavy lifting and positioning of car body panels with 3927 N of thrust, utilizing the 650 mm stroke to span wide assembly gaps.
Pallet Dispenser Actuation
Moves empty or loaded pallets along high-throughput packaging lines, relying on the SUS304 rod to resist moisture and contamination.
Heavy Goods Diverting
Pushes large cartons or totes across heavy-duty conveyor systems, where the integrated magnet enables fast CMSE sensor signaling for sorting logic.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX650S the Right Cylinder?
When sizing this actuator, stepping down to the 80 mm bore drops the 0.5 MPa push force to 2513 N, while moving up to the 125 mm bore increases it to 6136 N. Because this model utilizes a 650 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external linear guide or utilize a guided cylinder assembly.
This SAI100X650-S configuration specifies a PT tapered port thread, a G1/2 air supply connection, and an M20x1.5 rod thread. It includes adjustable air cushions at both ends to regulate piston deceleration. Note that if your application must hold a load vertically during a complete loss of air pressure, this standard cylinder will drift; you must specify the SAIL variant with an air-released lock or the BSAI clamp-lock model instead.
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 SAI100BX650S FAQ
