Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375CM
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375CM is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 375mm 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 MI25X375CM
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, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of adjustable cushioning.
For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which safely accounts for friction and flow losses. That same 0.5 MPa input translates to a vertical lift capacity of about 12.5 kg when you apply a 2:1 safety margin. Air enters via a 1/8 inch port, and the rear CM round end cover provides a clean, axial port orientation. Note that because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG or EMSG magnetic switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375CM Is Used
Package Diverting Arm
Swings a lightweight sorting gate on a packaging line, using the 245.3 N push force to reliably redirect cartons at high cycling speeds.
Vertical Parts Lift
Raises small component trays weighing up to 12.5 kg between conveyor tiers, benefiting from the stainless build in humid factory zones.
Clamping Fixture
Secures aluminum housings for a CNC machining operation, applying consistent holding pressure via the 1/8 inch port and CM round end cover.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X375CM the Right Cylinder?
Sizing this 375 mm stroke model requires looking at both neighbors. If your task needs less force, the Ø20 bore provides 157.0 N of push at 0.5 MPa; stepping up to the non-ISO Ø32 bore yields 402.2 N if you need significantly more power. The 375 mm stroke is well within the 500 mm maximum standard stroke for this bore, keeping it a standard catalog item. Because the piston travels a long distance, ensure your mounting configuration—whether LB foot, FA flange or TC trunnion—prevents side loading and rod bending. The CM round end cover dictates a straight rear port alignment, so verify your tubing routing clears adjacent mechanics.
Remember that a standard double-acting cylinder like this drifts when air pressure is lost or the valve is centered. The TPU bumpers only soften the end-of-stroke impact; they do not function as a brake or lock. If your mechanism must hold a vertical load securely during an emergency stop or air loss, you must add an external rod lock or a pilot-operated check valve to the system.
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 MI25X375CM FAQ
This double-acting cylinder uses a 1/8 inch port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion, and its ISO 6432 mounting dimensions fit standard mini-cylinder brackets.
