Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 200mm 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 MI25X200CM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. Its stainless barrel and piston rod resist mild corrosion, giving it a real edge over painted-steel or aluminium alternatives in damp or washdown environments. The rear CM round cover provides a clean, compact finish for simple back-end mounting.
At 0.5 MPa it generates 206.1 N of pull force, and plan for roughly 147 N of actual work to keep a safe margin. That equates to lifting about 12.5 kg vertically, letting you match real part weights easily. Air arrives through a 1/8 inch port, and fixed TPU bumper pads decelerate the piston at both stroke ends. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CM Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using 245.3 N of thrust, with the stainless build surviving occasional washdowns.
Vertical Parts Lift
Raises lightweight plastic totes weighing up to 12.5 kg through a 200 mm stroke, relying on the CM round end for simple top mounting.
Small Press Ejection
Kicks stamped aluminium parts out of a die zone, where the fixed TPU bumpers absorb the end-of-stroke impact without needing adjustment.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200CM the Right Cylinder?
When sizing this 200 mm stroke actuator, compare it against its neighbours: a Ø20 bore provides 157.0 N of push at 0.5 MPa, while stepping up to a Ø32 yields 402.2 N. This model sits comfortably in the middle for medium-force tasks. Since it lacks a magnet, order an -S variant if your sequence requires CMSG, DMSG or EMSG sensors. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion hardware.
Remember that a plain double-acting cylinder drifts when air is removed or the valve centres, as the fixed TPU pads only soften the stroke-end impact rather than locking the rod. Fit an external rod lock or pilot-operated check valve to hold a suspended load. Furthermore, across a 200 mm extension, minimise side-loading to prevent rod bending and premature seal wear.
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 MI25X200CM FAQ
This double-acting cylinder pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa, and the air port is 1/8 inch.
Yes, the Ø25 bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and brackets. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches; you must select an -S variant for position sensing.
