Airtac MI25~40 Stainless Steel Mini Cylinder MI25X10R
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X10R is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 10mm 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 MI25X10R
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles very short 10 mm strokes with precision. The riveted round-body construction uses a stainless barrel and rod, offering mild corrosion resistance that outlasts painted aluminium in damp or washdown environments. An R back cover configures the air supply axially into the rear, keeping hose routing tidy when space is tight.
Because the stroke is so brief, fixed TPU bumper pads effectively absorb the end-of-travel impact without needing adjustment. Plan for roughly 147 N of actual work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a safe 2:1 margin. This SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; choose an -S variant if position feedback is required.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X10R Is Used
Short-Stroke Part Clamping
Uses the 245.3 N push at 0.5 MPa to grip aluminium castings on a machining fixture, with the 10 mm travel providing rapid actuation.
Package Deflector Gate
Pivots a routing flap to sort small cartons on a packaging line, benefiting from the stainless build during periodic washdowns.
Pallet Stopper Pin
Extends 10 mm to block pallet movement on a gravity roller conveyor, holding safely with a 12.5 kg vertical-lift equivalent margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X10R the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157 N, while moving up to a 32 mm bore raises it to 402 N. This model sits comfortably in the mid-range for mini actuators. The 1/8" port matches the bore standard, and the male M10x1.25 rod thread provides a robust attachment point for short-stroke clamping.
With its 10 mm travel, rod bending is negligible, but remember that a standard cylinder drifts when air is removed or a valve centres—the TPU pads only decelerate the stroke end and never act as a lock. For suspended loads that must hold position, specify an external rod lock or a pilot-operated check valve. The Ø25 dimension conforms to ISO 6432 mounting interfaces, dropping directly into standard mini-cylinder brackets and clevises.
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 MI25X10R FAQ
The 25 mm bore generates 245.3 N push and 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. It features a 1/8" air port and a male M10x1.25 rod thread.
The Ø25 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder foot, flange and clevis brackets. However, because this specific SKU lacks a magnet, it cannot accept CMSG, DMSG or EMSG sensors; you must specify an -S variant for position sensing.
