Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40R is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 40mm 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 MI16X40R
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 40 mm strokes with ease. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Its 1/8" port and M6x1.0 male rod thread provide a robust pneumatic connection for mid-range mini tasks.
Featuring an R axial-in rear cover, the unit integrates seamlessly into tight machinery layouts. The fixed TPU bumper pads decelerate the piston at stroke ends without adding adjustable cushioning bulk. For practical sizing, plan for roughly 60 N of real work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40R Is Used
Package Deflection
Sort light cardboard cartons on a packaging line by pushing them off a belt using the 100.5 N thrust and 40 mm travel.
Clamp Ejection
Eject small aluminium machined parts from a fixture, utilising the 5.1 kg vertical lift capacity to clear the work area.
Valve Actuation
Toggle small process valves in a damp washdown area where the stainless steel barrel prevents mild corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40R the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 version drops the 0.5 MPa push force to 56.5 N, while moving up to the Ø20 bore increases it to 157.0 N. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position sensors; you must select an -S variant if your control system requires stroke detection. The R back cover provides an axial-in port orientation, which helps streamline tubing in cramped spaces.
Because it relies on fixed TPU bumpers rather than an adjustable air cushion, consider the MIC variant for high-speed operations. Note that a standard cylinder drifts when air is lost or the valve is centred, as the bumper only softens the end-of-stroke impact and acts as neither a brake nor a lock. To suspend a load safely, install 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 MI16-20 Stainless Steel Mini Cylinder MI16X40R FAQ
This 16 mm bore cylinder features a 1/8" port and a 6 mm rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum of 20.5 kgf at 1.0 MPa.
Yes, the Ø16 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. However, this specific SKU lacks a magnet, so you cannot mount CMSG, DMSG or EMSG switches unless you upgrade to an -S model.
