About the Airtac SAI63 Standard Cylinder SAI63X510S
The AirTAC SAI63X510-S is a double-acting profile cylinder built to the ISO 15552 standard, featuring a 63mm bore and a 510mm stroke. Because 510mm exceeds the standard maximum of 1500mm for this bore family, it is supplied as a made-to-order non-standard stroke unit. It generates a push force of 1559 N at 0.5 MPa and 2182 N at 0.7 MPa, making it suitable for medium-duty industrial handling.
This variant includes the -S magnet option for use with CMSE and DMSE reed switches, which mount directly into the dual sensor grooves machined into both sides of the extruded aluminum barrel. It uses a standard carbon steel piston rod and PT tapered port threads (G3/8), ensuring broad compatibility with existing pneumatic infrastructure.

Where the Airtac SAI63 Standard Cylinder SAI63X510S Is Used
Automated Press Ejection
Provides the 1559 N push force at 0.5 MPa needed to reliably eject stamped parts from a press bed, utilizing the 510mm stroke to clear the lower die entirely.
Pallet Transfer Pusher
Transitions heavy product pallets across a 500mm conveyor gap, where the integrated -S magnet allows CMSE sensors to confirm the fully extended push position.
Vertical Package Sorter
Diverts medium-weight packages on a sorting line, relying on the adjustable end cushions to safely decelerate the 63mm piston over the long 510mm travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63X510S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, while stepping up to the 80mm bore yields 2513 N if your application requires moving substantially heavier masses. The G3/8 port and M16x1.5 rod thread are dictated by the 63mm bore size.
Because this unit features a 510mm stroke, the extended unsupported rod length makes it highly susceptible to bending under side loads. To prevent premature rod-bearing wear or piston scoring, mount an external guide rail or use a fully guided cylinder for heavy off-center loads. Note that the standard adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load if air pressure is lost. For position holding without live pressure, specify the SAIL (air-released lock) variant or an external pilot-operated check valve.
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 SAI63X510S FAQ
At 0.5 MPa, the 63mm bore provides a push force of 1559 N and a pull force of 1402 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI series is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same 63mm bore size.
