About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5U
Generating about 100 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles short 5 mm positioning tasks with precision. The riveted round body and Ø6 mm piston rod shrug off mild corrosion, outperforming painted alternatives in damp environments. It features a 1/8" port and a U-type 90-degree rear cover for flexible mounting orientation.
Because the stroke is extremely short, fixed TPU bumper pads easily absorb the end-of-travel impact without requiring adjustment. Plan for roughly 60 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting a 5.1 kg part vertically against gravity. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5U Is Used
Micro-Clamping Jigs
Secures delicate electronic components during PCB routing using the 5 mm stroke, applying a safe 60 N of holding force without crushing the part.
Small Part Diverter
Pushes lightweight plastic caps on a packaging line, where the stainless steel barrel withstands daily washdown and the short stroke maximizes cycles.
Insertion Press
Drives small dowel pins into aluminum housings, leveraging the 100.5 N push force at 0.5 MPa for precise, low-travel seating.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X5U the Right Cylinder?
When sizing this 16 mm bore, dropping down to an Ø12 model reduces the push force to 56.5 N at 0.5 MPa, while stepping up to a Ø20 increases it to 157 N. The 5 mm stroke is ideal for clamping or ejecting tiny parts where a longer travel would waste cycle time. Its ISO 6432 mounting dimensions allow it to drop directly into standard mini-cylinder brackets and clevises.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the rod. You will need an external pilot-operated check valve to hold a suspended load. If your application requires position feedback, select the -S magnet variant instead, as this base unit cannot accept a switch.
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 MI16X5U FAQ
This 16 mm bore cylinder features a 1/8" port and a Ø6 mm rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant to enable magnetic sensing. The unit uses a U-type 90-degree back cover and conforms to ISO 6432 mounting dimensions.
