Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SR is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 10mm 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 MI20X10SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 10 mm strokes with precision. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp production areas. Its compact footprint drops right into standard ISO 6432 mini-cylinder brackets and clevises, simplifying spares.
With a 1/8 inch port and an R axial-in rear cover, the pneumatic routing sits neatly along the cylinder axis for tight assemblies. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. For real work at 0.5 MPa, plan for roughly 94 N of safe load, which means it can lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SR Is Used
Short-Stroke Clamping
Ideal for locking small electronic components onto a PCB router bed, using the 10 mm travel to secure parts without overextending the work envelope.
Film Feed Cut-off
Drives a compact guillotine blade on a vertical form-fill-seal machine, where the 157 N push force at 0.5 MPa cleanly snips thin packaging film.
Ejector Gate Actuation
Pops small plastic mouldings out of an inspection chute, using the integrated magnet to trigger an EMSG sensor and confirm the ejection stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10SR the Right Cylinder?
When sizing this 20 mm bore, the smaller MI16 offers about 100 N of push at 0.5 MPa, while stepping up to the MI25 yields 245 N if you need to move heavier jigs. This model includes the -S magnet for position feedback and features an R axial-in back cover for inline porting. The fixed TPU bumper pads soften the stroke-end impact but do not act as an adjustable air cushion.
Because it is a double-acting actuator, the piston will drift if air pressure drops or the valve is centred, so add an external rod lock or pilot check valve if your application must hold a vertical load securely. The very short 10 mm stroke keeps rod-bending side-loads minimal, but always ensure the load travels on a smooth linear guide.
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 MI20X10SR FAQ
This 20 mm bore cylinder has a 1/8 inch 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 of 32 kgf at 1.0 MPa.
No, the piston drifts if air is lost and the fixed TPU bumper pads only decelerate the stroke end rather than acting as an adjustable air cushion or a locking brake. For vertical load holding, you must fit an external rod lock or pilot-operated check valve.
