About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X370SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding actuation with a 370 mm stroke. The Ø25 mm bore operates on a 1/8" port and conforms to ISO 6432 mounting dimensions, dropping seamlessly into standard mini-cylinder brackets and clevises. Its riveted stainless barrel and rod naturally resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown environments.
Fixed TPU bumper pads absorb end-of-stroke impact, while the integrated piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. For real-world sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a safe 2:1 margin. The CA rear pivot cover provides a robust clevis mount for angular articulation.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X370SCA Is Used
Package Diverter Gate
Actuates a heavy routing flap on a packaging line, using the 245.3 N thrust to push mixed-parcel loads reliably at speeds up to 800 mm/s.
Pallet Component Pusher
Indexes cardboard cartons onto a palletizing station, where the 370 mm stroke provides the extended reach needed to clear the conveyor bed.
Textile Loom Tensioner
Adjusts a tensioning roller via the CA pivot mount, maintaining consistent fabric tension in a humid production environment that exploits the stainless build.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X370SCA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, stepping down to a Ø20 bore yields 157.0 N, whereas a Ø32 bore jumps to 402.2 N if your payload requires more authority. Because a standard double-acting cylinder drifts when air is removed or a valve is centered, you must add an external rod lock or pilot check valve to suspend a vertical load safely. The TPU bumpers only decelerate the stroke end and cannot act as a brake.
The 370 mm stroke falls within the 500 mm maximum for this bore, but at this length side-loading and rod bending are real risks; ensure rigid guidance and accurate alignment to prevent premature seal wear. This SKU includes the -S magnet for sensors and the CA pivot back cover, making it ideal for pivoting mechanisms where rear articulation is required.
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 MI25X370SCA FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end; they do not lock the rod. The piston will drift if air is lost, so an external rod lock is needed to hold a load. Because this SKU has the -S magnet, it supports CMSG, DMSG and EMSG reed or electronic switches for position feedback.
