About the Airtac SAI63 Standard Cylinder SAI63X580S
The AirTAC SAI63X580-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 580mm stroke. It delivers a robust push force of 1559 N at 0.5 MPa, making it well-suited for extended travel automation tasks. Equipped with a magnetic piston (-S), it integrates seamlessly with CMSE and DMSE reed switches fitted into the dual sensor grooves on the extruded aluminum barrel.
This model utilizes a standard carbon steel piston rod and a PT tapered port thread (G3/8). Operating efficiently between 30-800 mm/s, it includes adjustable air cushions at both ends to absorb kinetic energy. As a genuine AirTAC component, it provides a reliable, dimensionally interchangeable replacement for any standard ISO 15552 profile cylinder.

Where the Airtac SAI63 Standard Cylinder SAI63X580S Is Used
Extended Travel Lifting
Ideal for elevating heavy platens over long vertical distances where the 1559 N push force at 0.5 MPa is sufficient to overcome gravity and friction.
Pallet Pusher
Transfers pallets between adjacent conveyor lines, utilizing the 580mm stroke to bridge wide gaps without requiring multi-stage actuators.
Automated Storage Gate
Actuates swinging gates or diverters in automated storage systems, where the magnetic piston allows position confirmation via DMSE switches.
Is the Airtac SAI63 Standard Cylinder SAI63X580S the Right Cylinder?
If your application requires less thrust, stepping down to the 50mm bore yields 982 N at 0.5 MPa, whereas upgrading to the 80mm bore provides 2513 N. Because this 580mm stroke exceeds 300mm, side loads can cause rod-bearing bending; utilize an external guide rail or a guided cylinder to prevent premature wear. To hold a load securely without live air pressure, select the SAIL (lock) or BSAI (clamp-lock) variant, as standard air cushions only decelerate the piston and will not prevent drifting. This unit matches the ISO 15552 mounting interface for direct replacement using LB, FA, or TC accessories.
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.
