About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X210SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 210 mm travel tasks. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion and washdown, outperforming painted alternatives in damp environments. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position detection.
For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The U-style 90-degree rear cover simplifies compact pivot mounting. Fixed TPU bumper pads absorb stroke-end impact without adding bulk.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X210SU Is Used
Diverting Gate Actuation
Provides the 245.3 N push needed to pivot heavy sorting gates on packaging conveyors, withstanding damp washdowns via its stainless construction.
Vertical Carton Lifting
Utilizes the 210 mm stroke to raise 12.5 kg cartons between roller tiers, safely operating within a 2:1 vertical lift margin at 0.5 MPa.
U-Mounted Lever Mechanism
Leverages the 90-degree U rear cover to drive mechanical linkages in textile machinery, allowing compact pivoting without extra clevis brackets.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X210SU the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, the smaller Ø20 bore provides 157.0 N, while the larger Ø32 offers 402.2 N if you need substantially more push. This 210 mm stroke is well within the 500 mm maximum, though at extended lengths you should minimize side-loading to prevent rod bending. The ISO 6432 mounting interface drops directly into standard mini-cylinder brackets and clevises.
Remember that a standard cylinder drifts when air is lost or the valve centers; the TPU bumpers only decelerate the stroke end and never act as a lock. To hold a vertical load securely, add 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 MI25X210SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 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 is 1/8" and the male rod thread is M10x1.25.
No, the piston drifts if air is lost; the fixed TPU bumper pads only decelerate the stroke end, so use an external rod lock for holding. Because this SKU includes the -S magnet, it supports CMSG, DMSG and EMSG reed or electronic switches.
