Airtac MI25~40 Stainless Steel Mini Cylinder MI25X190SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X190SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 190mm 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 MI25X190SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion. The Ø25 mm bore operates on a 1/8" port, and the 190 mm stroke falls well within the 500 mm standard limit. Its riveted stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because the bore is Ø25, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the rear CA clevis provides a robust pivot point. Fixed TPU bumper pads absorb stroke-end impact to protect the mechanism. For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X190SCA Is Used
Package Diverter Arm
Uses the CA clevis to pivot a diverter gate on a packaging line, relying on the 245.3 N push force to redirect heavy cartons reliably.
Pallet Stacking Pusher
Employs the 190 mm stroke to push cardboard blanks into a stacking nest, benefiting from the stainless build in humid warehouse zones.
Textile Loom Tensioner
Actuates a fabric tensioning roller where the 12.5 kg vertical lift capacity and ISO 6432 mounting dimensions ensure smooth, repeatable tracking.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X190SCA the Right Cylinder?
When sizing this unit, the Ø20 bore below offers 157.0 N of push at 0.5 MPa, whereas stepping up to the Ø32 bore yields 402.2 N, so the Ø25 sits perfectly for medium-duty tasks. The CA rear clevis mount is ideal for pivoting loads, but remember that a plain double-acting cylinder drifts if air pressure is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and will not lock the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve. Furthermore, a 190 mm stroke generates leverage, so ensure the rod thread (M10x1.25) and pivot are aligned to prevent side-load bending.
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 MI25X190SCA FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The CA back cover provides a rear pivot clevis for angular movement, and fixed TPU bumper pads decelerate the piston at stroke ends without acting as an adjustable air cushion.
