About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X650SCMTC
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks. The Ø32 bore uses a 1/4" port and a Ø12 piston rod with an M10x1.25 male thread. Because the 650 mm stroke exceeds the 500 mm standard maximum, this unit is manufactured as a made-to-order item. The stainless-steel barrel and rod supply mild corrosion resistance, performing reliably in damp or washdown environments where painted steel would degrade. Fixed TPU bumper pads absorb impact energy at the stroke extremes, and the rolled riveted body keeps the assembly compact.
For practical sizing, plan for a safe working load of roughly 241 N rather than the absolute maximum rating. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches, while the CM round back cover and TC trunnion mounting provide versatile installation options for long-stroke mechanisms.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X650SCMTC Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics sorting line, using the 402.2 N push force to redirect parcels reliably at high throughput.
Pallet Positioning Plunger
Extends 650 mm to locate empty pallets at a wrapping station, where the long stroke and TC trunnion mount handle the required reach and minor misalignment.
Textile Loom Tensioner
Maintains consistent fabric tension in a humid manufacturing environment, leveraging the stainless steel construction to resist mild corrosion and washdown.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X650SCMTC the Right Cylinder?
When sizing this actuator, compare it against adjacent bores: the Ø25 delivers 245.3 N of push at 0.5 MPa, whereas the larger Ø40 provides 628.3 N. The Ø32 hits a practical middle ground for mid-range force requirements. If your mechanism must maintain its position during a compressed air loss or when the directional valve is centered, this standard cylinder will drift; you should integrate an external rod lock or a pilot-operated check valve for secure load holding. The fixed TPU bumpers only decelerate the piston near the end of travel and do not act as a braking mechanism.
Due to the extended 650 mm stroke on this Ø32 bore, carefully manage side loading to prevent rod bending and premature seal wear. The TC trunnion mount is particularly useful here, as it accommodates minor alignment shifts along the long axis. Furthermore, the -S magnet allows seamless integration of CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
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 MI32X650SCMTC FAQ
This double-acting cylinder features a 1/4" air port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not function as a lock. To hold a vertical load securely, you must install an external rod lock or a pilot-operated check valve.
