About the Airtac SAI63 Standard Cylinder SAI63X40
The AirTAC SAI63X40 is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It provides a robust push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for compact clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that resists debris buildup.
This specific configuration features a standard carbon steel piston rod and PT (tapered) port threads. For environments requiring position detection, the barrel features integrated sensor grooves on both sides, ready to accept CMSE or DMSE switches when a magnet is specified. If your assembly demands multi-position stopping, consider the related SAIJ adjustable-stroke variant.

Where the Airtac SAI63 Standard Cylinder SAI63X40 Is Used
Compact Clamping
Ideal for holding medium-weight machined components firmly in place during light milling or drilling operations.
Package Ejection
Provides rapid, forceful ejection of finished goods off a conveyor line into secondary packaging within tight machine footprints.
Gate Diverter
Actuates short-stroke diverter gates to route products between processing lanes with reliable 1559 N force.
Is the Airtac SAI63 Standard Cylinder SAI63X40 the Right Cylinder?
Selecting the SAI63X40 is optimal when the 1559 N thrust at 0.5 MPa perfectly matches your load requirement without inducing unnecessary cylinder bulk. If your application requires slightly less force, stepping down to the 50 mm bore yields 982 N, whereas upgrading to the 80 mm bore provides 2513 N. The 40 mm stroke offers rapid cycling in tight spaces.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For fail-safe load holding, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) variant. To ensure exact dimensional interchangeability, match the 63 mm bore, 40 mm stroke, G3/8 PT port, and desired mounting accessory (such as LB foot or TC trunnion).
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 SAI63X40 FAQ
At an operating pressure of 0.5 MPa, the SAI63X40 generates a push (extend) force of 1559 N and a pull (retract) force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X40 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders of the same bore and stroke. It serves as a direct drop-in replacement for mounting interfaces.
