About the Airtac SAI100 Standard Air Cylinder SAI100BX50
The AirTAC SAI100X50 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 50mm stroke. It provides a robust push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty clamping and high-force pressing over short distances. The extruded aluminum barrel design omits tie rods, yielding a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
Per your configuration, this unit uses a SUS304 stainless steel rod (material code B) for superior corrosion resistance and ships with PT tapered port threads. Because no magnet is specified, it lacks the internal magnetic ring required for reed or solid-state sensor switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX50 Is Used
Heavy-Duty Stamping
Ideal for short-stroke pressing and stamping tasks requiring high immediate impact force over a 50mm travel distance.
Pallet Stopping
Provides substantial stopping power for heavy pallets on packaging lines, utilizing the 3927 N push force at 0.5 MPa.
Industrial Clamping
Secures large workpieces during machining operations, taking advantage of the robust 100mm bore profile barrel design.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX50 the Right Cylinder?
If you need slightly less force, the 80mm bore neighbor yields 2513 N at 0.5 MPa, whereas stepping up is unnecessary for most 50mm stroke tasks. When ordering a replacement, verify the 100mm bore, 50mm stroke, G1/2 port, M20x1.5 rod thread, and your required mounting accessory like an FA flange or TC trunnion. Since this short stroke is highly rigid, side-load bending is minimal compared to longer strokes.
Remember that the standard SAI does not hold loads safely upon air pressure loss. The adjustable air cushions only decelerate the piston near the stroke ends rather than locking it. For fail-safe load holding, consider the SAIL variant with an air-released lock 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 SAI100BX50 FAQ
At an operating pressure of 0.5 MPa, the SAI100X50 cylinder provides a push force of 3927 N and a pull force of 3681 N. It can reach up to 5497 N push force at 0.7 MPa.
Because this specific configuration does not include the -S magnet option, it cannot support reed or solid-state switches like CMSE or DMSE sensors. You would need to specify the -S option to use magnetic sensors.
