About the Airtac SAI63 Standard Cylinder SAI63AX750S
The AirTAC SAI63X750-S is a double-acting ISO 15552 profile cylinder engineered for demanding linear motion tasks. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore actuator utilizes a 750 mm stroke to execute extended travel cycles. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnet for position sensing, this unit operates seamlessly with CMSE and DMSE switches seated in the dual sensor grooves. For corrosive resilience, the piston rod is fashioned from SUS420J2 stainless steel, while adjustable air cushions at both ends tame kinetic energy near the stroke limits.

Where the Airtac SAI63 Standard Cylinder SAI63AX750S Is Used
Extended Transfer Pushing
Moves heavy workpieces along lengthy conveyor segments using the full 750 mm stroke and 1559 N push force at 0.5 MPa.
Automated Material Handling
Actuates large diverter gates or positioning stops in packaging lines where the 63 mm bore provides substantial kinetic authority.
Long-Reach Clamping
Extends to secure oversized assemblies in machining fixtures, relying on SUS420J2 stainless rod durability for repeated cycles.
Is the Airtac SAI63 Standard Cylinder SAI63AX750S the Right Cylinder?
Selecting this 63 mm bore actuator makes sense when a 50 mm bore falls short of the required 982 N push force at 0.5 MPa, yet an 80 mm bore providing 2513 N would be physically oversized. The 750 mm stroke demands careful attention to mechanical stability; long unsupported rods are susceptible to bending under side loads. Employ an external guide rail or a guided cylinder configuration to prevent rod-bearing wear and premature seal failure.
As a dimensionally interchangeable ISO 15552 component, it replaces equivalent profile cylinders directly when matching the 63 mm bore, 750 mm stroke, G3/8 PT port, and desired mounting accessory like a TC trunnion. Note that the adjustable cushions decelerate the piston but do not secure the load; if pressure drops, the rod will drift. Deploy a SAIL lock variant for fail-safe holding.
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 SAI63AX750S FAQ
