About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CMTC
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial workloads within a compact footprint. The Ø25 mm bore operates on 1/8" ports and features a male M10x1.25 rod thread. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb stroke-end impact to protect the mechanism.
For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to safely lifting about 12.5 kg vertically with a 2:1 margin. The CM round rear cover and included TC trunnion mounting provide flexible installation options. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CMTC Is Used
Package Diverting Arm
Actuates a routing gate on a logistics conveyor, using the 245.3 N push force to swing heavy cardboard cartons into secondary packing lanes.
Pouch Sealing Press
Drives the upper jaw of a continuous band sealer, applying consistent downward pressure via the TC trunnion mount to secure food-grade pouches.
Textile Loom Tensioner
Adjusts the guide bar on a weaving machine, withstanding humid conditions thanks to the stainless-steel build while maintaining thread tension.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CMTC the Right Cylinder?
When sizing this 25 mm bore, compare it against its neighbours: the Ø20 generates 157.0 N of push at 0.5 MPa, while the larger Ø32 provides 402.2 N. If your application requires position feedback, step up to an -S magnet variant to enable sensor switches. The 90 mm stroke is well within the 500 mm maximum, keeping the assembly rigid with minimal rod bending risk.
Remember that venting the air supply or centering the valve will cause the piston to drift, as the fixed TPU bumpers only decelerate the stroke end rather than locking the rod. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MI25X90CMTC FAQ
This 25 mm bore cylinder uses a 1/8" port and a Ø10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. Mechanically, it uses the ISO 6432 mounting interface for standard mini-cylinder brackets, and the included TC trunnion allows pivoting installations.
