About the Airtac SAI32 Standard Cylinder SAI32X650
The AirTAC SAI32X650 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and 650mm stroke. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for medium-duty linear actuation over extended distances. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
Beyond the standard specifications, this configuration utilizes a carbon steel piston rod for robust mechanical strength in industrial environments. Because it lacks a magnet, it does not support direct stroke sensing; if your application requires end-of-stroke confirmation, the -S variant with CMSE or DMSE sensors is necessary. The standard TPU seals handle typical shop air temperatures, while adjustable air cushions at both ends manage piston deceleration.

Where the Airtac SAI32 Standard Cylinder SAI32X650 Is Used
Material Transfer
Pushes packages or pallets along extended conveyor lines where a 650mm stroke is required to clear adjacent machinery.
Automated Storage
Actuates sliding doors or routing gates in automated storage and retrieval systems using 402 N of force.
Component Diverting
Diverts secondary components on an assembly line, utilizing the full 650mm travel to reach across the belt.
Is the Airtac SAI32 Standard Cylinder SAI32X650 the Right Cylinder?
Choosing this 32mm bore makes sense when your load requires around 402 N of push force at 0.5 MPa. If your application demands less energy, stepping down is not an option within the SAI series, but moving up to a 40mm bore increases the push force to 628 N for heavier payloads. At 650mm of stroke, the unsupported rod length is substantial; side loads will cause rod-bearing bending and premature wear. To manage this, integrate an external guide rail or select a guided cylinder to prevent mechanical deflection.
This model features PT tapered port threads (G1/8) and standard carbon steel rod material. Because it is a double-acting cylinder, it relies on live air pressure to move in both directions. If power or air is lost, the piston will drift and cannot hold a load vertically; for fail-safe holding, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of the standard SAI.
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 SAI32 Standard Cylinder SAI32X650 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X650 is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders with the same 32mm bore and 650mm stroke, matching the G1/8 port and standard mounting accessories.
