About the Airtac SAI63 Standard Cylinder SAI63X750
The AirTAC SAI63X750 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 750mm stroke. It delivers a push force of 1559 N at 0.5 MPa, making it well-suited for medium-duty automation tasks requiring extended travel distances. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and maintenance.
This variant comes standard with a carbon steel piston rod and lacks a built-in magnet. For environments requiring high-temperature resistance, the seals can be upgraded from standard TPU to Viton (H). Its standardized ISO 15552 mounting interface ensures strict dimensional interchangeability with other globally recognized standard cylinders.

Where the Airtac SAI63 Standard Cylinder SAI63X750 Is Used
Material Handling Lines
Ideal for pushing or lifting products along extended conveyor sections where a 750mm travel distance is required to transfer goods between workstations.
Automated Assembly
Provides the necessary 1559 N push force at 0.5 MPa to actuate large jigs or press components into place over a long linear stroke.
Palletizing Mechanisms
Used in low-rise palletizing or depalletizing equipment where extended reach and medium force are needed to index packaging materials.
Is the Airtac SAI63 Standard Cylinder SAI63X750 the Right Cylinder?
When selecting this model, consider your force requirements carefully. If your application demands less force, stepping down to the 50mm bore yields 982 N at 0.5 MPa, while moving up to the 80mm bore provides 2513 N. At 750mm of stroke, the unsupported rod is highly susceptible to bending under side loads. To prevent premature wear on the rod bearing and seal damage, always pair this cylinder with an external guide rail or use a dedicated guided cylinder.
The SAI63X750 uses a G3/8 port and M16x1.5 rod thread. It is a drop-in replacement for any ISO 15552 cylinder matching these dimensions. Note that this standard cylinder does not hold its load when air pressure is removed; if your application requires fail-safe holding, consider the SAIL locking variant or an external rod lock.
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 SAI63X750 FAQ
At an operating pressure of 0.5 MPa, the SAI63X750 generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
No, the standard SAI cylinder relies on live air pressure and will drift or drop if pressure is lost. The adjustable air cushion only decelerates the piston at stroke end; it does not act as a lock. For load holding, use the SAIL variant or an external rod lock.
