About the Airtac SAI63 Standard Cylinder SAI63X800
The AirTAC SAI63X800 is a double-acting ISO 15552 profile cylinder built for long-trroke linear motion. It delivers a robust 1559 N of push force at 0.5 MPa, making it suitable for moving heavy loads over an 800 mm travel distance.
This model features a standard carbon steel piston rod for durability and accepts NBR seals for general-purpose pneumatics. Because it lacks a magnet, position sensing requires external reed or solid-state switches mounted to the cylinder body.

Where the Airtac SAI63 Standard Cylinder SAI63X800 Is Used
Material Transfer
Pushes heavy pallets or workpieces across an 800 mm gap on automated conveyor lines using 1559 N of thrust.
Door Opening Systems
Extends large industrial machine safety doors or gates requiring a long 800 mm travel distance.
Indexing Mechanisms
Drives long-stroke indexing or positioning stages where a full 800 mm extension cycle is needed.
Is the Airtac SAI63 Standard Cylinder SAI63X800 the Right Cylinder?
With an 800 mm stroke, this 63 mm bore cylinder operates near its maximum standard stroke limit of 1500 mm. At 0.5 MPa, it provides 1559 N of thrust; if your application requires less force, stepping down to a 50 mm bore yields 982 N while saving space and air consumption.
Long unsupported strokes exceeding 300 mm introduce side-load risks that can bend the rod or damage the rod bearing. To mitigate this, use an external guide rail or a guided cylinder to absorb lateral forces. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If position holding is required when air pressure drops, integrate an external pilot-operated check valve or select the SAIL variant.
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.
