About the Airtac SAI100 Standard Air Cylinder SAI100BX550S
The AirTAC SAI100X550-S is a double-acting ISO 15552 profile cylinder engineered to deliver robust linear motion. It provides a substantial push force of 5497 N and a pull force of 3681 N at a 0.7 MPa operating pressure. The 550 mm stroke is well-suited for transferring heavy components across sizable automated workstations. This unit is configured with a SUS304 stainless steel piston rod (option B), providing excellent corrosion resistance for harsh or washdown manufacturing environments.
As a genuine AirTAC component, this profile barrel design incorporates sensor grooves on both sides for straightforward switch mounting. Because this specific model includes the -S magnet option, it is fully compatible with CMSE and DMSE series reed and solid-state sensors for precise end-of-stroke detection. The extruded aluminum barrel ensures a rigid yet lightweight structure that drops directly into standardized ISO 15552 mounting interfaces.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX550S Is Used
Heavy Material Transfer
Ideal for pushing heavy pallets or metal castings across long 550 mm trajectories in automotive assembly lines, utilizing the 5497 N push force to overcome sliding friction.
Pallet Positioning
Executes mid-stroke positioning of large packaging pallets, where the SUS304 stainless steel rod prevents corrosion in humid logistics environments.
Press Ejection Systems
Provides the necessary stroke length and kinetic energy to eject finished stamped parts from large press beds, relying on adjustable end-cushions to absorb impact.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX550S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant yields a significant force jump, increasing push thrust from 3518 N to 5497 N at 0.7 MPa. If an application requires even greater thrust, stepping up to the 125 mm bore offers 8590 N at the same pressure. The G1/2 PT tapered port ensures high airflow to maintain velocity across the 550 mm travel distance.
With a stroke of 550 mm, the unsupported piston rod is susceptible to bending under lateral loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a fully guided cylinder for heavy off-center payloads. Note that the standard adjustable air cushions only decelerate the piston near the stroke ends; they will not hold a vertical load if air pressure is removed. For fail-safe load holding, integrate the SAIL pneumatic lock variant or an external rod 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 SAI100BX550S FAQ
At a standard 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
Yes. The SAI100X550-S is built to standard ISO 15552 mounting dimensions, making it dimensionally interchangeable with other ISO 15552 profile cylinders. You can swap it into existing foot, flange, or trunnion mounts using standard PT G1/2 pneumatic connections.
