About the Airtac SAI63 Standard Cylinder SAI63BX5S
The AirTAC SAI63X5-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke applications. It delivers a push force of 1559 N at 0.5 MPa, providing substantial thrust within a highly compact footprint. This specific configuration includes a -S magnet for direct mounting of CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel.
Configured with a SUS304 stainless steel rod (option B), this model is highly suitable for environments where moisture or minor corrosion is a concern. The PT tapered port threads ensure a robust, leak-free pneumatic connection. Its standardized mounting interface makes it a direct replacement for other ISO 15552 cylinders.

Where the Airtac SAI63 Standard Cylinder SAI63BX5S Is Used
High-Force Clamping
Provides 1559N of clamping force at 0.5MPa for securing heavy metal workpieces during machining operations.
Short-Stroke Ejection
Ideal for quickly pushing finished parts off a conveyor line without extending far into the machinery workspace.
Compact Positioning
Fits into tight machine cells to actuate gates or stops with high thrust in a minimal 5mm travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63BX5S the Right Cylinder?
Selecting this 63mm bore over the 50mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, while stepping up to an 80mm bore would yield 2513 N. The 5mm stroke is optimal for high-force clamping or short ejection tasks where a longer rod would waste space and increase susceptibility to side-load damage.
Because the standard SAI cylinder is double-acting, it relies on continuous air pressure to hold position; if air is lost, the piston will drift. For applications requiring dead-stop holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock model. To swap this cylinder into an existing ISO 15552 setup, match the 63mm bore, 5mm stroke, G3/8 PT port, and preferred mounting accessory like an FA flange.
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 SAI63 Standard Cylinder SAI63BX5S FAQ
