About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The 16 mm bore uses a 1/8" port and a 6 mm piston rod, while the rear CA clevis bracket simplifies pivot mounting. Built with a riveted stainless barrel and rod, it resists mild corrosion and washdowns better than painted alternatives.
Its fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. Plan for roughly 60 N of actual work at 0.5 MPa to ensure smooth cycling, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CA Is Used
Textile Loom Tensioning
Uses the rear CA pivot to maintain consistent yarn tension on a weaving loom, applying around 60 N of smooth force to the guide arm.
Carton Flap Folding
Drives a compact mechanical arm to fold corrugated cardboard flaps prior to sealing, benefiting from the stainless build in damp packing areas.
Sorter Diverter Gate
Actuates a lightweight routing gate on a package conveyor, relying on the 40 mm stroke to push parcels efficiently at speeds up to 800 mm/s.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40CA the Right Cylinder?
When sizing this 16 mm bore, dropping down to the Ø12 variant reduces push force to 56.5 N at 0.5 MPa, whereas stepping up to the Ø20 bore increases it to 157.0 N. The 40 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. To track piston position, select the MI16X40CA-S magnet version instead, as this base unit cannot accept sensors.
Remember that venting the air supply causes the piston to drift, as the fixed bumpers only decelerate the end of travel rather than locking the rod. Install an external pilot check valve or rod lock if your pivot mechanism must hold a suspended load securely during an air loss event.
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 MI16X40CA 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 force of 20.5 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet, so CMSG, DMSG or EMSG switches cannot be fitted; you need the -S variant for sensing. Additionally, it uses fixed TPU bumper pads for end-of-stroke deceleration, not the adjustable air cushion found on MIC variants.
