About the Airtac SAI32 Standard Cylinder SAI32X50SN
The AirTAC SAI32X50-S is a double-acting ISO 15552 profile cylinder offering a compact 32mm bore and 50mm stroke. It provides 402 N of push force at 0.5 MPa, making it well-suited for short, precise positioning tasks in tight machine layouts.
This variant includes a magnetic piston for use with CMSE and DMSE series reed switches, fitting neatly into the dual sensor grooves machined into the extruded aluminum barrel. It utilizes standard carbon steel for the piston rod, NBR seals for reliable pneumatic operation, and PT tapered port threads for secure, leak-free fittings.

Where the Airtac SAI32 Standard Cylinder SAI32X50SN Is Used
Packaging Diverters
Ideal for actuating short-stroke routing gates and pushers on high-speed packaging conveyors where 402 N at 0.5 MPa is sufficient to redirect light cartons.
Small Part Clamping
Provides reliable holding force for small fixture clamps in CNC machining centers, utilizing its magnetic piston to confirm clamp position via sensor feedback.
Component Ejection
Excellent for ejecting lightweight molded or stamped components from press dies, with adjustable cushions ensuring soft contact at the 50mm stroke end.
Is the Airtac SAI32 Standard Cylinder SAI32X50SN the Right Cylinder?
If your application requires slightly less force, stepping down is not an option below 32mm in the SAI range, but stepping up to a 40mm bore yields 628 N at 0.5 MPa for heavier moving masses. Because this is a 50mm stroke, side-load stress on the rod bearing is minimal, though external guides are always recommended for offset loads. To mount this cylinder, use standard ISO 15552 accessories like FA or FB flanges, or LB foot brackets. Remember that the adjustable air cushions only decelerate the piston at end-of-stroke; this cylinder will drift if air pressure is lost. For applications requiring true position holding without constant air pressure, 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.
