About the Airtac SAI50 Standard Cylinder SAI50BX65S
The AirTAC SAI50X65-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit is tailored for mid-range actuation. The 65 mm stroke provides rapid, short-travel movement for compact machinery.
Built with a SUS304 stainless steel rod (option B), this variant offers superior corrosion resistance for demanding environments. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE sensor switches seated in the dual side grooves of the extruded aluminum barrel. Fluid ports feature a PT tapered thread design for secure, leak-free pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50BX65S Is Used
Component Clamping
Generates reliable 982 N clamping force at 0.5 MPa to secure workpieces during machining operations.
Package Diverting
Executes rapid 65 mm linear strokes to push or divert packages along high-speed sorting conveyors.
Gate Control
Actuates safety gates or access barriers with precise movement and integrated CMSE position sensing.
Is the Airtac SAI50 Standard Cylinder SAI50BX65S the Right Cylinder?
When sizing this actuator, consider the neighboring 40 mm bore if your load requires less force, as it provides 628 N at 0.5 MPa. If your application demands heavier thrust, stepping up to the 63 mm bore yields 1559 N at 0.5 MPa. Because 65 mm is a short stroke, rod-bearing bending is negligible, but always ensure external guides support any lateral loads to prevent premature wear.
This model is dimensionally interchangeable per ISO 15552, making it a direct replacement for other standard profile cylinders. It utilizes a G1/4 port, an M16x1.5 rod thread, and operates efficiently between 30-800 mm/s. Remember that the standard double-acting design relies on continuous air pressure to hold position; if power fails, the piston will drift. For fail-safe load holding, explore the SAIL variant with an air-released 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.
