About the Airtac SAI32 Standard Cylinder SAI32X315
The AirTAC SAI32X315 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 315mm stroke. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for light-duty positioning tasks over extended distances. The extruded aluminum barrel design omits tie rods, providing a clean exterior that easily drops into existing ISO 15552 mounting interfaces.
This configuration uses a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, standard magnetic sensing is not enabled out of the box; adding the -S option later allows CMSE or DMSE switches to ride the dual sensor grooves machined into the barrel.

Where the Airtac SAI32 Standard Cylinder SAI32X315 Is Used
Package Diverting
Ideal for pushing light cardboard cartons across conveyor belts over a 315mm gap without consuming excessive vertical space.
Component Sorting
Provides the precise 402 N force needed to eject small plastic or metal parts from machining centers into collection bins.
Light Stacking
Handles the vertical elevation of lightweight tote boxes in automated storage systems, utilizing the full 315mm travel.
Is the Airtac SAI32 Standard Cylinder SAI32X315 the Right Cylinder?
A 32mm bore provides 402 N of push force at 0.5 MPa. If your application requires greater thrust to overcome friction or move heavier payloads, stepping up to the 40mm bore increases that output to 628 N. For this 315mm stroke, the unsupported piston rod travels a significant distance; long strokes inherently increase the risk of rod-bearing bending under side loads. To prevent premature seal wear, consider using an external guide rail or a fully guided cylinder mechanism.
This model is dimensionally interchangeable with other ISO 15552 cylinders. To match this replacement exactly, confirm the 32mm bore, 315mm stroke, PT G1/8 port, and select appropriate mounting accessories like an FA flange or LB foot bracket. Note that a standard SAI does not hold its load when air pressure is removed; for position holding without live pressure, specify the SAIL lock or BSAI clamp-lock 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.
Airtac SAI32 Standard Cylinder SAI32X315 FAQ
At 0.5 MPa operating pressure, the SAI32X315 generates a push force of 402 N and a pull force of 345 N. At the maximum standard pressure of 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X315 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with older ISO 6431 and VDMA 24562 units. Just match the G1/8 port and mounting hardware.
