About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles robust actuation tasks. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted round body features a stainless barrel and rod, resisting mild corrosion in damp or washdown environments better than painted alternatives. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
Thanks to the built-in -S magnet, you can mount CMSG, DMSG or EMSG switches for position sensing. The CM round end back cover keeps the rear profile clean. For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin. Operating speed spans 30-800 mm/s.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCM Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 245.3 N of thrust, with the stainless rod resisting humid packing-room condensation.
Textile Loom Tensioner
Uses the 75 mm stroke to maintain yarn tension, relying on the CM round end and ISO 6432 dimensions for easy bracket integration.
Bin Gate Actuator
Opens small gravity-fed hopper gates for dry granules, lifting roughly 12.5 kg components vertically with a safe 2:1 margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X75SCM the Right Cylinder?
If 245.3 N push at 0.5 MPa is too much, step down to the Ø20 bore (157.0 N push); if you need more muscle, the Ø32 bore provides 402.2 N. This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors and the CM round end cover. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion brackets via the ISO 6432 mounting interface. Remember that a plain cylinder drifts when air is lost or a valve is centred, so add an external rod lock or pilot check valve for held loads. At a 75 mm stroke, side-load and rod-bending stress are minimal, but keep the guide alignment true.
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 MI25X75SCM FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. This Ø25 bore model uses a 1/8" air port and a Ø10 mm piston rod with an M10x1.25 male thread.
Yes to sensors, no to adjustable cushions. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. However, it only has fixed TPU bumper pads that decelerate the stroke end; for adjustable air cushioning you would need the MIC variant.
