About the Airtac SAI63 Standard Cylinder SAI63X35S
The AirTAC SAI63X35-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation in tight machinery layouts. It provides a robust 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it well-suited for high-impact clamping and holding tasks. The 35 mm stroke ensures rapid end-to-end cycling without occupying excessive axial space.
This variant includes a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches, which seat directly into the dual sensor grooves machined into the extruded aluminum barrel. It utilizes a standard carbon steel piston rod and features PT tapered port threads, ensuring a secure, leak-free pneumatic connection directly to your existing air line infrastructure.

Where the Airtac SAI63 Standard Cylinder SAI63X35S Is Used
Heavy-Duty Clamping
Generates 1559 N of clamping thrust at 0.5 MPa to secure heavy metal workpieces during CNC machining or welding operations.
Short-Stroke Diverting
Ideal for compact sorting stations where a rapid 35 mm extension pushes product lanes without extending into adjacent walkways.
Part Ejection
Delivers a fast, forceful punch to eject finished parts from press dies, utilizing the integrated adjustable air cushions to soften the stroke end.
Is the Airtac SAI63 Standard Cylinder SAI63X35S the Right Cylinder?
Selecting this 63 mm bore is optimal when a 50 mm bore (delivering 982 N push at 0.5 MPa) lacks the necessary thrust, but a larger 80 mm bore (2513 N) would be physically oversized for the envelope. The 35 mm stroke is tailored for brief, powerful movements. Because the stroke is well under 300 mm, rod-bearing bending from side loads is minimal, though external guides are always recommended if absorbing heavy lateral moments.
As a true ISO 15552 profile cylinder, this unit serves as a drop-in dimensional replacement for any comparable standard cylinder with a 63 mm bore, 35 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or LB foot brackets. Note that standard double-acting cylinders drift when air pressure is removed; if your process demands fail-safe load holding without live pressure, specify the SAIL variant equipped 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.
Airtac SAI63 Standard Cylinder SAI63X35S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X35-S is dimensionally interchangeable with any ISO 15552 profile cylinder of the same bore and stroke. It shares the standard G3/8 port and mounting dimensions, allowing a direct drop-in replacement.
