About the Airtac SAI63 Standard Cylinder SAI63BX30
The AirTAC SAI63X30 is a double-acting ISO 15552 profile cylinder engineered for compact, high-force actuation. Operating at 0.15-1.0 MPa, it generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The 30 mm stroke makes it highly effective for short-travel clamping and ejecting tasks where space is restricted.
This unit features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in wet or washdown environments. It utilizes PT tapered port threads and includes an extruded aluminum barrel with sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI63 Standard Cylinder SAI63BX30 Is Used
Short-Stroke Clamping
Ideal for securing heavy metal components during machining, utilizing its 1559 N push force within a tight 30 mm travel range.
High-Force Ejection
Perfect for knocking finished parts out of molds or presses quickly, where high kinetic energy is needed over a very short distance.
Washdown Positioning
The SUS304 stainless steel rod excels in food or chemical processing environments, resisting corrosion during frequent equipment washdowns.
Is the Airtac SAI63 Standard Cylinder SAI63BX30 the Right Cylinder?
Select this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the necessary power for heavy lifting, but you want to avoid the bulk of an 80 mm bore (2513 N). The 30 mm stroke provides rapid end-to-end movement without consuming excessive axial length.
For direct compatibility, match your existing bore and stroke dimensions, G3/8 PT ports, and mounting accessories like FA flanges or TC trunnions. Note that this standard cylinder relies on adjustable air cushions to decelerate the piston; it cannot hold a load if air pressure drops. Use the SAIL variant if pneumatic locking is required.
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 SAI63BX30 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, it is a dimensionally interchangeable ISO 15552 profile cylinder. You can drop it into existing setups by matching the 63 mm bore, 30 mm stroke, G3/8 ports, and mounting hardware.
