About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore operates on 1/8" ports and features 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 light, while fixed TPU bumper pads absorb impact at the stroke ends.
Because it includes the -S magnet, this unit supports CMSG, DMSG and EMSG position switches for closed-loop control. For practical sizing, plan for a safe working load of about 94 N, which means it can lift an 8 kg part vertically with a 2:1 safety margin. The R back cover provides an axial-in port orientation, simplifying manifold plumbing in tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SR Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, while the stainless build withstands humid packing rooms.
Small Parts Ejector
Ejects machined plastic components from a fixture with a 50 mm stroke, relying on the fixed TPU bumpers to soften stroke-end impact.
Bin Lid Actuator
Opens and closes access hatches on material bins, using the R axial-in port to save space and the -S magnet to confirm lid closure.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SR the Right Cylinder?
When sizing this 50 mm stroke model, the 157 N push force at 0.5 MPa sits comfortably between the smaller Ø16 bore (100.5 N) and the larger Ø25 bore (245.3 N). If your payload drops, step down to the 16 mm version; if you need more authority, the 25 mm is the next step up. Remember that a plain cylinder drifts when air is lost or the valve is centred, so add an external rod lock or pilot check valve if you must hold a vertical load.
The built-in magnet pairs directly with CMSG, DMSG or EMSG sensors for end-of-stroke confirmation. With a 50 mm stroke, side-load stress on the Ø8 mm rod is minimal, but ensure your front mounting uses standard ISO 6432 brackets to maintain alignment and prevent rod binding.
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 MI20X50SR FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must use an external rod lock or pilot-operated check valve to hold a suspended load.
