About the Airtac SAI63 Standard Cylinder SAI63X60
The AirTAC SAI63X60 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. With a 63 mm bore and 60 mm stroke, it is tailored for short-trroke ejection, clamping, and lifting operations. The extruded aluminum barrel omits tie-rods, providing a compact exterior that simplifies machine integration.
This variant features a standard carbon steel piston rod and PT tapered port threads. It includes adjustable air cushions at both ends to manage impact deceleration. For high-temperature environments up to +70 C, the standard TPU seals can be swapped for Viton (H) elastomers.

Where the Airtac SAI63 Standard Cylinder SAI63X60 Is Used
Short-Stroke Clamping
Ideal for securing heavy metal workpieces during CNC machining, utilizing its 1559 N push force at 0.5 MPa to prevent part shifting.
Package Ejection
Provides rapid, forceful ejection of dense cartons or components from conveyor lines within a compact 60 mm travel distance.
Lift and Transfer
Handles the vertical lifting of intermediate pallets or tooling plates in automated assembly cells where space is restricted.
Is the Airtac SAI63 Standard Cylinder SAI63X60 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the thrust for moving heavier fixtures, but an 80 mm bore (2513 N) would be physically oversized. The 60 mm stroke offers exact travel for compact pressing tasks. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal.
As a genuine ISO 15552 profile cylinder, it drops directly into standardized mounting interfaces using FA, FB, LB, or TC accessories. Note that this standard cylinder does not hold loads safely upon air loss; for fail-safe holding, select the SAIL or BSAI variant.
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 SAI63X60 FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X60 generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X60 is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts, provided the 60 mm stroke and G3/8 port align with your setup.
