About the Airtac SAI63 Standard Cylinder SAI63X750S
The AirTAC SAI63X750-S is a double-acting ISO 15552 profile cylinder engineered for long-distance linear actuation. It delivers a robust 1559 N of push force at 0.5 MPa, making it well-suited for moving substantial loads over its 750 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a magnet for proximity sensing and utilizes a standard carbon steel piston rod. The barrel features integrated sensor grooves on both sides, allowing straightforward installation of CMSE or DMSE reed switches to track piston position. For environments requiring elevated temperatures, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI63 Standard Cylinder SAI63X750S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 750 mm gap, utilizing the 1559 N thrust class to overcome friction on conveyor lines.
Automated Storage Retrieval
Actuates lifting or pushing arms in automated warehousing, relying on the integrated magnet for precise end-of-stroke position feedback.
Large Door Manipulation
Opens and closes heavy industrial machine guarding doors, benefiting from the adjustable air cushions to ensure smooth deceleration.
Is the Airtac SAI63 Standard Cylinder SAI63X750S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant is driven by the need for higher thrust, stepping up from 982 N to 1559 N at 0.5 MPa. If an application demands even greater force, the 80 mm bore offers 2513 N. Because this model features a 750 mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This cylinder operates effectively at speeds of 30-800 mm/s and features adjustable air cushions at both ends to absorb impact energy. It does not hold its position if air pressure is lost; applications requiring dead-load holding should utilize the SAIL (air-released lock) or BSAI (clamp-lock) variants. Replacement planning requires matching the 63 mm bore, 750 mm stroke, G3/8 PT ports, and the -S magnet option.
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.
