About the Airtac SAI100 Standard Air Cylinder SAI100BX5
The AirTAC SAI100X5 is a double-acting ISO 15552 profile cylinder engineered for short-stroke heavy-duty tasks. It provides a robust push force of 3927 N at 0.5 MPa and a pull force of 3681 N, making it highly effective for high-impact pressing and clamping operations.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance and a PT tapered port thread. While the 5 mm stroke is a non-standard made-to-order length, it retains the dual-sided sensor grooves of the extruded aluminum barrel, allowing for CMSE or DMSE switch integration when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX5 Is Used
Heavy-Duty Stamping
Ideal for short-stroke metal forming, riveting, and stamping tasks where the 3927 N push force at 0.5 MPa is applied in brief, high-impact bursts.
Pallet Clamping
Provides the necessary thrust to lock heavy pallets or workpieces securely in place during machining or transfer operations, utilizing the 100 mm bore power.
Brake & Stopper Mechanisms
Functions as a robust pneumatic stopper in conveyor systems, using the 5 mm stroke to absorb and halt moving loads without requiring a long extension.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX5 the Right Cylinder?
Choosing this 100 mm bore over the smaller 80 mm variant significantly increases thrust, stepping up from 2513 N to 3927 N at 0.5 MPa. The ultra-short 5 mm stroke is optimal when you need maximum holding power in a compact footprint, such as end-of-stroke cushioning blocks or short clamping jaws.
Because the SAI series relies on pneumatic pressure, the piston will drift if air is lost; for applications requiring true position holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model uses a G1/2 port, M20x1.5 rod thread, and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions.
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 SAI100BX5 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X5 is dimensionally interchangeable per the ISO 15552 standard, meaning it matches the mounting interface of other ISO 15552 profile cylinders. It uses a G1/2 port and M20x1.5 rod thread.
