Airtac MI25~40 Stainless Steel Mini Cylinder MI25X65SCM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X65SCM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 65mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X65SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. Its riveted stainless barrel and Ø10 mm rod shrug off mild corrosion, giving a real edge over painted alternatives in damp or washdown environments. A built-in piston magnet (-S) supports CMSG, DMSG and EMSG position switches.
For practical sizing, plan for about 147 N of real work at 0.5 MPa, which safely lifts a 12.5 kg part vertically with a 2:1 margin. The 1/8" port feeds air to extend and retract the rod, while fixed TPU bumper pads absorb the impact at stroke ends. The rear CM round cover keeps the body smooth for tight spaces. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-800 mm/s.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X65SCM Is Used
Package Diverting Gate
Swings a lightweight routing flap on a packaging line, using the 245.3 N thrust to positively push corrugated cartons onto a secondary belt.
Small Press Ejector
Kicks stamped metal blanks out of a die bed, where the stainless construction resists cutting fluid mist and the 12.5 kg safe lift clears the parts.
Bin Lid Actuation
Pivots a hinged lid on a bulk material hopper, relying on the CM round end and ISO 6432 dimensions to fit neatly into existing clevis brackets.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X65SCM the Right Cylinder?
If 245.3 N at 0.5 MPa is too much, step down to the Ø20 bore which provides 157.0 N of push force. If you need more muscle, the Ø32 bore jumps to 402.2 N. Remember that a plain double-acting 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 securely, add an external rod lock or a pilot-operated check valve.
This 65 mm stroke unit includes the -S magnet for CMSG/DMSG/EMSG sensors and uses a CM round rear cover. You can mount it via LB foot, FA flange, SDB pivot or TC trunnion hardware. For high-speed cycles requiring adjustable deceleration, consider the MIC variable air cushion variant instead of the fixed bumper pads found here.
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 MI25X65SCM 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. The air port is 1/8" and the male rod thread is M10x1.25.
Yes, the -S suffix means it has a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed and electronic switches directly onto the stainless-steel round body for position detection.
