About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact to protect the mechanism.
For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The unit features a 1/8" port, an M10x1.25 male rod thread, and a CA rear pivot cover. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185CA Is Used
Package Diverter Arm
Swings a diverter gate on a packaging line, utilizing the CA pivot bracket to cleanly route 12 kg cartons at speeds up to 800 mm/s.
Warehouse Lift Station
Raises lower-tier totes into a packing ergonomically optimal position, safely lifting components under the 12.5 kg vertical margin.
Textile Loom Tensioner
Maintains consistent fabric tension in a humid textile facility, leveraging the stainless steel construction to resist mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X185CA the Right Cylinder?
When sizing this 185 mm stroke model, verify your load against the 245.3 N push and 206.1 N pull ratings at 0.5 MPa. If your application requires less force, the Ø20 bore provides 157.0 N of push, while stepping up to the Ø32 bore yields 402.2 N. The 185 mm stroke is well within the 500 mm maximum for this bore, but at full extension you should minimize side-loading to prevent rod bending. The CA back cover supplies a rear pivot point for clevis mounting.
Remember that a standard double-acting cylinder drifts when air is lost or the valve centers; the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load securely, install an external rod lock or a pilot-operated check valve in the air circuit.
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 MI25X185CA 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 of 50 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion, and its ISO 6432 dimensions allow standard bracket mounting.
