About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. It features fixed TPU bumper pads that absorb stroke-end impact and a built-in magnet for position sensing.
Equipped with a 1/8" port and an M8x1.25 male rod thread, the unit operates at speeds of 30-800 mm/s. For practical sizing, plan for a safe working load of about 94 N, which means it can vertically lift roughly 8 kg with a 2:1 safety margin. The CM round end cover provides a compact rear profile for tight machine layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, utilizing the 157 N push force to redirect moderate-weight cartons efficiently.
Textile Loom Tensioner
Adjusts tensioning rollers in a damp textile manufacturing environment, leveraging the stainless-steel construction to resist humidity.
Bin Lid Actuation
Opens and closes access hatches on material bins, where the 160 mm stroke provides the necessary reach and the CM cover allows flush mounting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160SCM the Right Cylinder?
When sizing this 20 mm bore, compare it against the 16 mm bore offering 100.5 N push at 0.5 MPa, or step up to the 25 mm bore providing 245.3 N if your application requires greater thrust. Because this is a 160 mm stroke, ensure your mounting configuration—whether LB foot, FA flange, or TC trunnion—prevents excessive side loading to avoid rod bending. The included -S magnet allows seamless integration of CMSG, DMSG, or EMSG switches.
Remember that a standard pneumatic cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only decelerate the stroke end and do not function as a braking lock. To maintain a vertical load during an air loss event, incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 MI20X160SCM FAQ
This 20 mm bore cylinder has a 1/8" port. The thrust ratings are 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, and a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches along the body. It uses fixed TPU bumper pads to decelerate at stroke ends, not an adjustable air cushion.
