About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding linear motion across its 350 mm stroke. The Ø25 mm bore uses a 1/8 inch air port and an M10x1.25 male rod thread. Built with a riveted stainless barrel and rod, it resists mild corrosion and washdowns better than painted alternatives. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.
Plan for roughly 147 N of actual work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. Because the rear cover features a CA pivot clevis, it accommodates angular misalignment during extension. The Ø25 mm dimension strictly adheres to ISO 6432 mounting interfaces, ensuring compatibility with standard mini-cylinder brackets.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons reliably at 0.5 MPa.
Vertical Parts Press
Lowers a lightweight tooling head over 350 mm to seat bearings, leveraging the safe vertical lift capacity of 12.5 kg.
Textile Loom Tensioner
Pivots via the CA clevis to maintain fabric tension, relying on the stainless steel construction to endure humid manufacturing environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCA the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit, consider the neighbouring bores: a Ø20 generates 157.0 N, while a Ø32 provides 402.2 N. This model includes the -S magnet for CMSG/DMSG/EMSG sensors and a CA rear pivot cover. If your mechanism requires adjustable end-cushioning for high-speed cycles, evaluate the MIC variant instead of this fixed-bumper design.
At 350 mm, the stroke is well within the 500 mm maximum, but the extended Ø10 mm rod is vulnerable to side-loading; maintain alignment to prevent bending. Note that air loss or a centred valve causes the piston to drift, as the TPU pads only decelerate the end of travel rather than locking the load. Use a pilot-operated check valve for position holding.
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 MI25X350SCA FAQ
At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8 inch.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For holding a suspended load, install an external pilot-operated check valve or a rod lock.
