About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80CM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles substantial work within a compact riveted round body. The Ø25 bore conforms to ISO 6432 mounting dimensions, ensuring it drops directly into standard mini-cylinder brackets and clevises. 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, while the CM round end cover dictates the rear mounting and port orientation.
For practical sizing, plan for about 147 N of real work at 0.5 MPa, which safely lifts a 12.5 kg mass vertically with a 2:1 margin. The unit operates at 30-800 mm/s and features a 1/8" air port. 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 MI25X80CM Is Used
Package Diverter
Pushes medium-weight cartons off a sorting line using 245.3 N of thrust, surviving damp washdown areas thanks to the stainless construction.
Clamp Station
Secures aluminium extrusions during machining operations, safely applying around 147 N of holding force at 0.5 MPa.
Gate Actuator
Cycles an 80 mm stroke to open parts-feed chutes, utilising the CM round end cover for straightforward rear pivot mounting.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80CM the Right Cylinder?
When sizing this 80 mm stroke actuator, verify your payload against the 245.3 N push rating at 0.5 MPa. If you need less force, the Ø20 bore provides 157.0 N push, whereas stepping up to the Ø32 yields 402.2 N. For applications requiring position feedback, select the -S magnet variant to enable sensor switches. Remember that a plain cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. To suspend a load safely, install an external rod lock or pilot check valve.
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 MI25X80CM FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for sensing. The unit uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
