Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 75mm 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 MI20X75SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 75 mm stroke with a CM round rear cover. The riveted construction pairs a corrosion-resistant barrel and rod to survive damp or washdown environments better than painted alternatives. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb stroke-end impact. For real-world sizing, plan for a safe working load of about 94 N, which means it lifts roughly 8 kg vertically with a 2:1 safety margin. Air connects via a 1/8 inch port.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCM Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 75 mm stroke to push cartons into a secondary lane with precise position feedback.
Textile Loom Tensioner
Maintains yarn tension in a humid textile facility, leveraging the stainless steel barrel to resist moisture while applying steady clamping force.
Bin Lid Opener
Lifts lightweight access hatches on material hoppers, safely moving parts within the 8 kg vertical lift capacity via the CM round end pivot.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SCM the Right Cylinder?
If you need less force, the Ø16 bore provides 100.5 N push at 0.5 MPa; stepping up to the Ø25 yields 245.3 N. This Ø20 model strikes a middle ground with an 8 mm rod and M8x1.25 male thread. The CM round end dictates the rear mounting orientation, so verify your bracket geometry. Remember that a standard cylinder drifts if air pressure drops or the valve is centered—the TPU bumpers only decelerate the stroke end and will not lock the load. Use a pilot-operated check valve or an external rod lock if you need to hold position vertically.
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 MI20X75SCM FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port is 1/8 inch.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches. However, cushioning is via fixed TPU bumper pads that only decelerate the stroke end; it is not an adjustable air cushion. For adjustable cushioning, look at the MIC variant.
