About the Airtac SAI32 Standard Cylinder SAI32BX300S
The AirTAC SAI32X300-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting interfaces. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for a 300 mm stroke length. It is a genuine AirTAC component built to drop into existing ISO 15552 machinery layouts.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and a PT tapered port thread. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE switches housed within the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI32 Standard Cylinder SAI32BX300S Is Used
Light-Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic components out of a machining fixture over the 300 mm travel distance.
Package Diverting
Actuates a diverting arm on a packaging line, where the SUS304 rod provides necessary corrosion resistance in humid or washdown environments.
Drawer Actuation
Extends automated storage and retrieval system drawers, relying on CMSE sensors to confirm fully open and closed positions.
Is the Airtac SAI32 Standard Cylinder SAI32BX300S the Right Cylinder?
Selecting this 32 mm bore over a larger 40 mm option (which yields 628 N at 0.5 MPa) is ideal when spatial constraints dictate a smaller footprint while still requiring an extended 300 mm stroke. For this stroke length, the unsupported rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it provides dimensional interchangeability for straightforward replacement. Matching mounting accessories include LB foot brackets, FA flanges, or TC trunnions. Remember that the standard adjustable air cushions only decelerate the piston near stroke ends and do not lock the load; if pneumatic pressure is lost, the rod will drift. Use an external pilot-operated check valve for position holding.
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 SAI32BX300S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. If pressure increases to 0.7 MPa, the push force reaches 563 N.
Yes, the SAI32X300-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounting footprints using matching LB, FA, or TC accessories, provided the 300 mm stroke and PT porting match your setup.
