About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SCA
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 riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. A built-in piston magnet allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
Featuring a 185 mm stroke and a 1/8" port, it operates at speeds between 30-800 mm/s. Plan for about 60 N of real work at 0.5 MPa, which means it lifts roughly 5.1 kg vertically with a 2:1 safety margin. The fixed TPU bumper pads absorb end-of-stroke impact, while the CA rear pivot cover suits angular movement requirements.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SCA Is Used
Pivot-Actuated Guiding Arms
The CA rear clevis allows this 100.5 N cylinder to swing and index small guiding arms on a packaging line, absorbing pivot stress during the 185 mm travel.
Diverter Gate Actuation
Stainless construction withstands washdown while the piston magnet triggers DMSG sensors to confirm gate position when routing boxes at 0.5 MPa.
Small Part Ejection
Provides reliable push force to eject 5 kg assembled parts from a fixture, using the fixed TPU bumpers to soften the impact at the end of the 185 mm stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SCA the Right Cylinder?
When sizing this 16 mm bore, dropping down to a 12 mm bore reduces thrust to 56.5 N, whereas stepping up to a 20 mm bore increases it to 157.0 N (both rated at 0.5 MPa). The 185 mm stroke is well within the 500 mm maximum standard limit, though long strokes require careful alignment to prevent rod bending and side-load wear. Its ISO 6432 mounting dimensions ensure it drops directly into standard mini-cylinder brackets and clevises.
The included -S magnet supports position sensing, and the CA back cover provides a rear pivot point. Because the fixed TPU bumpers only decelerate the stroke end, a plain cylinder will drift if air is lost or the valve is centered; use an external rod lock or pilot-operated check valve to hold a load securely.
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 MI16X185SCA FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa, and the air port size is 1/8".
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a brake. If air is lost or the valve is centered, the piston will drift; an external rod lock or pilot check valve is required to hold a suspended load.
