About the Airtac SAI32 Standard Cylinder SAI32AX155
The AirTAC SAI32X155 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 155mm stroke. Because 155mm is not a standard catalog length, this unit is configured as a made-to-order non-standard stroke. It delivers a push force of 563N at 0.7 MPa, making it well-suited for compact automation tasks requiring precise intermediate travel.
Beyond the standard spec table, this model is built with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads, and while it lacks a standard magnet, the extruded aluminum barrel retains dual sensor grooves for future CMSE or DMSE switch integration.

Where the Airtac SAI32 Standard Cylinder SAI32AX155 Is Used
Compact Part Ejection
Uses the 563N push force at 0.7 MPa to eject small molded components from a press without requiring excessive space.
Package Diverting
Actuates a diverting arm at exactly 155mm to route small parcels on a conveyor line with precise stroke control.
Clamp Actuation
Extends to secure lightweight workpieces in a machining fixture, utilizing the SUS420J2 rod to resist shop-floor moisture.
Is the Airtac SAI32 Standard Cylinder SAI32AX155 the Right Cylinder?
Select this 32mm bore when an application requires exactly 155mm of travel and a push force around 563N at 0.7 MPa. If your load requires less force, stepping down is not an option below 32mm in the SAI series, but stepping up to a 40mm bore yields 879N of push force at 0.7 MPa for heavier demands.
Since this is a non-standard stroke, ensure your mounting setup perfectly accommodates the exact 155mm extension. For any application requiring the load to be held securely without continuous air pressure, do not rely on the standard air cushions; instead, specify an external pilot-operated check valve or choose the SAIL variant with an air-released lock.
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 SAI32AX155 FAQ
At an operating pressure of 0.7 MPa, this 32mm bore cylinder provides a push force of 563N and a pull force of 345N. The theoretical maximum force at 1.0 MPa is 82 kgf.
Yes, the SAI32X155 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders with matching 32mm bore and 155mm stroke dimensions, utilizing standard FA, LB, or TC mounting accessories.
