Airtac MI16-20 Stainless Steel Mini Cylinder MI16X18SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X18SCA is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 18mm 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 MI16X18SCA
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 Ø16 mm bore uses a 1/8" port and an M6x1.0 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp washdown environments. Fixed TPU bumper pads absorb stroke-end impact, while the built-in magnet supports CMSG, DMSG and EMSG sensors.
Plan for roughly 60 N of actual work at 0.5 MPa to maintain safe margins, which translates to lifting about 5.1 kg vertically. The 18 mm short stroke excels in tight spaces, and the CA rear pivot cover allows direct clevis mounting for angular actuation tasks.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X18SCA Is Used
Diverter Gate Actuation
Uses the 18 mm stroke to snap sorting flaps on a packaging line, relying on the 100.5 N thrust to push light cardboard cartons reliably.
Small Parts Ejection
Ejects machined plastic components from a CNC fixture, utilising the CA pivot mount to accommodate the angular ejection path.
Lab Sample Handling
Moves fluid vials within a testing station, where the stainless construction prevents corrosion from accidental chemical spills.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X18SCA the Right Cylinder?
When sizing this model, consider the neighbouring bores: the smaller Ø12 generates 56.5 N push, whereas the larger Ø20 provides 157.0 N at 0.5 MPa. The Ø16 hits a practical middle ground for moderate force. Because the standard MI lacks a locking mechanism, the piston will drift if air pressure drops or the valve is centred; integrate a pilot-operated check valve or external rod lock if you must hold a suspended load. The included -S magnet enables position sensing, and the CA pivot back cover suits articulated mechanisms. For this 18 mm stroke, side-load risks are minimal, but always verify rod alignment to prevent premature seal wear.
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 MI16X18SCA FAQ
This Ø16 mm bore cylinder features a 1/8" port and an M6x1.0 male rod thread. 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, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; the piston will drift on air loss, so use a pilot check valve for holding. It includes a CA pivot clevis back cover and conforms to ISO 6432 mounting dimensions. The built-in -S magnet allows CMSG, DMSG and EMSG sensor integration.
