About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and piston rod resist mild corrosion, making it highly suitable for damp environments or washdown zones where painted alternatives fail. A 1/8" port supplies air to drive the 12 mm rod, while fixed TPU bumper pads absorb end-of-stroke impacts.
For practical sizing, plan for a safe working load of roughly 241 N, which accounts for friction and real-world dynamics. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The CM round end cover provides a clean rear finish, and because this 450 mm stroke falls within the 500 mm maximum standard, it ships as a standard configuration rather than a special order.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450CM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor belt, utilizing the 402.2 N push force to redirect parcels reliably.
Vertical Material Press
Provides consistent downward pressure for a light-duty assembly press, relying on the 450 mm stroke to accommodate varying part heights.
Washdown Component Ejector
Pushes machined parts out of a damp machining cell, leveraging the stainless steel construction to withstand humid operating conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450CM the Right Cylinder?
When sizing this 32 mm bore unit, the smaller 25 mm variant offers 245.3 N of push at 0.5 MPa, whereas stepping up to the 40 mm bore yields 628.3 N. Choose this model when your application requires that middle-ground thrust. Because this is a non-magnet SKU, it cannot accept CMSG, DMSG, or EMSG position switches; you must select an -S variant if electronic sensing is required.
At a 450 mm stroke, side loading becomes a critical factor. Ensure your mounting arrangement—whether LB foot, FA flange, or TC trunnion—maintains strict alignment to prevent rod bending and premature seal wear. Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as an adjustable air cushion. Furthermore, if the air supply drops, the piston will drift, so fit an external rod lock or pilot check valve if you need to hold a suspended load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450CM FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa, the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for sensing, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for position detection. It features fixed TPU bumper pads for end-of-stroke deceleration, not an adjustable air cushion.
