Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 250mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because it conforms to ISO 6432 mounting dimensions, this unit drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for a safe working load of roughly 94 N, which means it can lift about 8 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250CM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cartons weighing up to 8 kg into secondary lanes.
Textile Loom Tensioner
Maintains thread tension in a humid manufacturing environment, leveraging the stainless steel construction to prevent mild corrosion.
Bin Lid Lifter
Raises the lid of a parts bin across a 250 mm travel distance, dropping easily into standard clevis mounts via its ISO 6432 dimensions.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250CM the Right Cylinder?
When sizing this 250 mm stroke model, verify your load against the 157 N push and 131.9 N pull figures at 0.5 MPa. If you need less force, the Ø16 bore provides 100.5 N push, while the larger Ø25 bore offers 245.3 N for heavier demands. The CM round end back cover provides a clean rear profile for this configuration. Keep in mind that a plain cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end rather than locking the load, so add an external rod lock or pilot check valve if you need to hold position.
With a 250 mm stroke on an Ø8 mm rod, be mindful of side loads that could cause rod bending or premature seal wear. Ensure your guiding geometry is square to prevent binding. This unit operates between 0.15-1.0 MPa and travels at speeds of 30-800 mm/s.
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 MI16-20 Stainless Steel Mini Cylinder MI20X250CM FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion.
