About the Airtac SAI32 Standard Cylinder SAI32X85S
The AirTAC SAI32X85-S is a double-acting ISO 15552 profile cylinder designed for direct compatibility with standardized mounting interfaces. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit with an 85 mm stroke is built for compact, high-cycle automation. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that resists debris accumulation.
This specific configuration includes a magnet for proximity sensing and uses a standard carbon steel piston rod. Sensors mount directly into the dual side grooves, allowing seamless integration of CMSE or DMSE switches without requiring additional brackets.

Where the Airtac SAI32 Standard Cylinder SAI32X85S Is Used
Small Part Ejection
Ideal for pushing lightweight plastic or metal components out of machining centers using its 563 N thrust capability.
Package Diverting
The 85 mm stroke provides rapid actuation for diverting small cartons on a high-speed packaging conveyor line.
Clamp Actuation
Well-suited for operating small pneumatic clamps holding delicate workpieces during light assembly operations.
Is the Airtac SAI32 Standard Cylinder SAI32X85S the Right Cylinder?
Choose this 32 mm bore when an application requires 563 N of push force at 0.7 MPa. If your project demands less energy, stepping down is difficult as this is the smallest standard SAI size; however, if you need substantially more thrust, consider the 40 mm bore which provides 879 N at the same pressure. Because this model features a magnet (-S), it is ready for precise end-of-stroke detection.
For tasks involving vertical loads or those requiring pneumatic pressure to maintain position during an emergency stop, note that a standard cylinder will drift or drop when air is exhausted. In such scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. The PT tapered port threads ensure a robust, mechanically sealed pneumatic connection.
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 SAI32X85S FAQ
