About the Airtac SAI32 Standard Cylinder SAI32X250S
The AirTAC SAI32X250-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 250mm stroke. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for light-duty positioning and clamping tasks over moderate distances.
This variant includes a standard carbon steel piston rod and PT tapered port threads. Equipped with a magnet (-S), it integrates seamlessly with CMSE and DMSE sensor switches thanks to the extruded aluminum barrel's dual sensor grooves on both sides.

Where the Airtac SAI32 Standard Cylinder SAI32X250S Is Used
Component Ejection
Provides 402 N of push force at 0.5 MPa to reliably eject small machined parts from an assembly fixture over a 250 mm travel distance.
Package Sorting
Actuates a sorting arm along a 250 mm stroke to divert small lightweight packages on a conveyor line, utilizing the integrated magnet for end-of-stroke confirmation.
Pallet Stops
Functions as a pneumatic stop gate for lightweight pallets, extending 250 mm to halt product flow before retracting to allow passage.
Is the Airtac SAI32 Standard Cylinder SAI32X250S the Right Cylinder?
If an application requires less extension force, stepping down is not an option below 32mm in this series, but moving up to a 40mm bore yields 628 N at 0.5 MPa for heavier loads. At 250mm of travel, side loads can exert leverage on the rod bearing; using an external guide rail or a fully guided cylinder helps prevent premature wear and rod bending.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders with matching 32mm bore, 250mm stroke, G1/8 ports, and standard mounting accessories like LB or FA. Note that this standard cylinder relies on live air pressure to move; it will not hold a load if pressure is lost. For position holding, consider the SAIL locking 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.
