About the Airtac SAI63 Standard Cylinder SAI63BX10S
The AirTAC SAI63X10-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it highly effective for compact clamping and pressing tasks. The 10 mm stroke provides rapid, precise end-to-end movement without occupying excessive machine space.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, allowing seamless integration with CMSE or DMSE switches. Fluid ports feature PT tapered threads, and adjustable air cushions at both ends ensure smooth deceleration even at operating speeds up to 800 mm/s.

Where the Airtac SAI63 Standard Cylinder SAI63BX10S Is Used
Short-Stroke Clamping
Ideal for securing heavy workpieces in machining fixtures where a 10 mm travel quickly locks parts in place using 1559 N of force.
Riveting & Staking
Provides concentrated impact for small riveting or staking operations, utilizing the 63 mm bore's robust push force in a compact footprint.
Ejector Mechanisms
Suits short-distance product ejection from molds or conveyors, where the SUS304 rod ensures durability against repetitive, high-cycle impacts.
Is the Airtac SAI63 Standard Cylinder SAI63BX10S the Right Cylinder?
Selecting this 63 mm bore cylinder is optimal when your application requires 1559 N of push force at 0.5 MPa but has strict spatial limits. If your mechanism needs less force, stepping down to a 50 mm bore yields 982 N, whereas moving up to an 80 mm bore provides 2513 N. The 10 mm stroke is highly specialized; ensure your load requirements match this brief travel distance.
Because the stroke is only 10 mm, side-load stress on the rod bearing is minimal compared to longer strokes. However, this standard double-acting cylinder does not hold its position if air pressure is lost; the piston will drift. For applications requiring pneumatic locking without live pressure, consider the SAIL variant or an external rod lock. This model serves as a dimensionally interchangeable direct replacement per ISO 15552 standards, utilizing a G3/8 port and compatible with FA, LB, or TC mounting accessories.
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.
