About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200R
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion across its 200 mm stroke. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its R back cover features an axial-in port orientation, simplifying rear air routing in tight machinery layouts.
The stainless-steel barrel and piston rod provide reliable mild corrosion resistance for damp or washdown environments. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact without adding bulk.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200R Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 245.3 N thrust to push heavy cartons smoothly into a secondary lane at speed.
Textile Loom Tensioner
Adjusts the tension bar on an industrial weaving machine, where the stainless build withstands humid manufacturing environments and fibre dust.
Pallet Labelling Arm
Extends 200 mm to press an automated label applicator against inbound pallets, relying on the axial R rear port to keep the assembly flush against the frame.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X200R the Right Cylinder?
When sizing this 200 mm stroke model, the smaller Ø20 bore offers 157.0 N push at 0.5 MPa, while the larger non-ISO Ø32 bore provides 402.2 N if you need substantially more thrust. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; choose an -S variant if your control system requires electronic stroke confirmation. You can mount it via LB foot, FA flange, SDB pivot or TC trunnion hardware.
At 200 mm of extension, the Ø10 mm rod is susceptible to bending under severe side loads, so ensure guided load alignment to prevent premature seal wear. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and will not act as a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI25X200R FAQ
This Ø25 mm bore cylinder features a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG or EMSG switches. You must select an -S variant of the MI series to enable magnetic position sensing.
