About the Airtac SAI32 Standard Cylinder SAI32BX185
The AirTAC SAI32X185 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a custom 185mm stroke. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for compact automation tasks requiring a mid-length extension. This unit omits a piston magnet, focusing purely on mechanical actuation.
Built with a SUS304 stainless steel rod (option B), this model provides excellent corrosion resistance for demanding environments. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage end-of-stroke impacts. The extruded aluminum barrel integrates sensor grooves on both sides, allowing for straightforward installation of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI32 Standard Cylinder SAI32BX185 Is Used
Compact Part Ejection
Uses its 402 N push force at 0.5 MPa to reliably eject small molded components from a fixture on a 185mm extension.
Package Diverting
Actuates a routing arm to sort lightweight packages along a conveyor line, utilizing the adjustable cushions for smooth stops.
Drawer Actuation
Extends and retracts a testing equipment drawer, taking advantage of the SUS304 rod for corrosion resistance in varied climates.
Is the Airtac SAI32 Standard Cylinder SAI32BX185 the Right Cylinder?
Selecting this 32mm bore cylinder is ideal when your application requires around 402 N of push force at 0.5 MPa. If your project demands less force, stepping down is not an option in this series, but moving up to a 40mm bore increases the push force to 628 N. Because this 185mm stroke is a non-standard made-to-order length, ensure your lead times account for custom manufacturing.
This model uses PT tapered ports and an M10x1.25 rod thread. For mounting, it supports standard ISO 15552 accessories like LB foot brackets or FA flanges. Since the standard SAI lacks a locking mechanism, the piston will drift if air pressure is lost; for applications requiring strict position holding without live pressure, consider the SAIL variant with an air-released lock or an external pilot check valve. Additionally, with a stroke of 185mm, verify that your load is guided to prevent rod-bearing bending.
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 SAI32BX185 FAQ
At an operating pressure of 0.5 MPa, the SAI32X185 generates a push force of 402 N. If you increase the pressure to 0.7 MPa, the push force reaches 563 N.
Yes, the SAI32X185 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. It uses standard ISO mounting accessories and PT tapered ports.
