Airtac MI25~40 Stainless Steel Mini Cylinder MI25X30CA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X30CA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 30mm 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 MI25X30CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in a compact footprint. The 25 mm bore uses a 1/8" port and a 10 mm rod. Because the stainless barrel and rod resist mild corrosion, it outlasts painted alternatives in damp or washdown settings. Plan for about 147 N of actual work at 0.5 MPa, which means it can lift roughly 12.5 kg vertically with a 2:1 safety margin.
The 30 mm stroke moves quickly, and fixed TPU bumper pads absorb the impact at both ends. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets. This specific CA back cover features a rear pivot clevis for angular load alignment. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to an -S variant.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X30CA Is Used
Pivoting Clamp Arms
Uses the CA rear clevis to swing a 25 mm bore clamping arm, applying 245.3 N of force to hold metal stock during a milling operation.
Package Deflector Gates
Executes a fast 30 mm stroke to push diverts on a packaging line, where the stainless body withstands daily washdowns.
Vertical Part Ejection
Lifts small machined parts out of a fixture, safely moving loads up to 12.5 kg vertically with a 2:1 safety margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X30CA 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. Choose this model when your calculated load sits near 147 N. The CA rear clevis is perfect for pivoting mechanisms, but remember that venting the air or centering the valve causes the piston to drift; these bumpers only decelerate the stroke end and will not hold a load. For suspended weights, install a pilot check valve or external rod lock. If your machine runs at high cycle speeds and needs end-of-stroke tuning, consider the MIC variable cushion variant instead.
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 MI25X30CA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. This 25 mm bore cylinder uses a 1/8" air port.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG switches, you must select the -S magnet variant. Additionally, the CA back cover on this model provides a rear pivot clevis for angular mounting.
