About the Airtac SAI63 Standard Cylinder SAI63BX140S
The AirTAC SAI63X140-S is a double-acting ISO 15552 profile-barrel cylinder engineered to deliver 1559 N of push force and 1402 N of pull force at 0.5 MPa. This specific 140 mm stroke length is highly effective for mid-range automation tasks that require substantial thrust without occupying excessive machine footprint.
Equipped with a SUS304 stainless steel rod (option B), this unit provides superior corrosion resistance for humid or chemically exposed manufacturing environments. The integrated -S magnet enables direct mounting of CMSE or DMSE sensor switches along the dual-sided extruded barrel grooves, ensuring precise end-of-stroke detection.

Where the Airtac SAI63 Standard Cylinder SAI63BX140S Is Used
CNC Workholding
Clamps heavy machining fixtures securely against a vise, utilizing the 1559 N push force to stabilize metal components during aggressive milling operations.
Package Diverting
Actuates a routing arm on a high-speed sorting line, leveraging the 140 mm stroke to push medium-weight cartons into secondary processing lanes.
Material Bending
Provides the primary pushing thrust for a pneumatic press brake, forming light-gauge sheet metal with reliable 0.5 MPa operational pressure.
Is the Airtac SAI63 Standard Cylinder SAI63BX140S the Right Cylinder?
Select this 63 mm bore when an application demands roughly 1559 N of thrust at 0.5 MPa, bridging the gap between the 50 mm bore (982 N) and the larger 80 mm bore (2513 N). For operations needing less force, stepping down to a 50 mm bore saves space, while heavy-duty lifting may require upgrading to the 80 mm variant.
Because this is a double-acting pneumatic actuator, it cannot maintain its position if air pressure is lost or exhausted; the piston will drift. If your workflow requires static load holding without constant air pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. This standard SAI model guarantees a seamless, dimensionally interchangeable direct replacement for any existing ISO 15552 mounting interface, utilizing a PT G3/8 port and standard 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 SAI63 Standard Cylinder SAI63BX140S FAQ
Operating at 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X140-S is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 compliant actuators. Just ensure your setup matches the G3/8 PT port and utilizes the appropriate -S magnet for sensor compatibility.
