About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X140SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with ease. The stainless-steel barrel and piston rod provide reliable mild corrosion resistance, making it well-suited for damp production environments where painted steel alternatives would degrade. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke ends to protect your mechanism.
Equipped with a 1/8" air port and an M10x1.25 male rod thread, the unit integrates smoothly into existing pneumatic setups. The CM round end back cover offers a clean rear profile for versatile mounting. Thanks to the built-in piston magnet, you can easily mount CMSG, DMSG, or EMSG switches for precise position detection. For practical sizing, plan for a safe working load of about 241 N, which translates to lifting roughly 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X140SCM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to redirect medium-weight parcels reliably without stalling.
Bottling Line Ram
Drives a sorting pusher in a beverage plant, where the stainless-steel construction withstands routine washdowns and the CM rear cover allows tight axial spacing.
Pallet Component Ejector
Pushes cardboard dividers off an assembly station, relying on the 140 mm stroke and the integrated magnet to confirm ejection via a DMSG sensor.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X140SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore reduces your push force to 245.3 N at 0.5 MPa, while moving up to the largest 40 mm bore increases it to 628.3 N. This 140 mm stroke falls well within the 500 mm maximum standard stroke, ensuring standard availability. Remember that a plain double-acting cylinder like this will drift if air pressure is lost or the valve is centered; the TPU bumpers only decelerate the stroke end and do not act as a lock. To hold a vertical load securely, incorporate an external rod lock or a pilot-operated check valve into your circuit. You can utilize LB foot, FA flange, SDB pivot, or TC trunnion mounts to fit your frame.
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 MI32X140SCM FAQ
This double-acting cylinder features a 1/8" 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 brake. You must use an external rod lock or pilot check valve to hold a load safely.
