About the Airtac SAI32 Standard Cylinder SAI32AX85S
The AirTAC SAI32X85-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit is tailored for precise 85 mm strokes. Its extruded aluminum barrel omits tie-rods, providing a clean, standardized mounting interface that drops directly into existing ISO 15552 fixtures.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches fitted into the dual grooves machined along both sides of the barrel. Fluid ports utilize a PT tapered thread type.

Where the Airtac SAI32 Standard Cylinder SAI32AX85S Is Used
Small Parts Clamping
Ideal for securing lightweight aluminum or plastic components during CNC machining, utilizing its 402 N push force at 0.5 MPa for reliable holding without deforming the part.
Package Diverting
Provides the rapid 85 mm stroke needed to actuate routing gates on packaging lines, with the integrated magnet allowing DMSE sensors to confirm gate position.
Textile Machinery
The SUS420J2 rod material resists moisture and lint in textile manufacturing environments, ensuring smooth actuation of thread tensioning and cutting mechanisms.
Is the Airtac SAI32 Standard Cylinder SAI32AX85S the Right Cylinder?
Select this 85 mm stroke variant when an application requires short, snappy movements that do not warrant the full extension of a standard 100 mm cylinder, yet need more reach than a 75 mm unit. If your fixture demands less force, stepping down is unfeasible as 32 mm is the smallest SAI bore; however, if you need roughly 879 N at 0.7 MPa, step up to the 40 mm bore.
Because the stroke is under 300 mm, rod-bearing bending from side loads is minimal, though external guides are always recommended for rigid payloads. This standard SAI does not hold position upon loss of air pressure; the piston will drift if the valve is centered or exhausted. For suspended loads requiring safety locking, specify the SAIL variant or an external pilot check valve. To match this cylinder, use the 32 mm ISO 15552 mounting dimensions, G1/8 port, and choose LB or FA accessories with the -S magnet option.
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 SAI32AX85S FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder generates a push force of 563 N and a pull force of 345 N. The maximum theoretical force at 1.0 MPa is 82 kgf.
