About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 450 mm stroke with a CA pivot clevis. The 1/8 inch port and M8x1.25 male rod thread ensure straightforward pneumatic and mechanical integration. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments.
Built to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. For practical sizing, plan for a safe working load of roughly 94 N, which means it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CA Is Used
Package Diverter Arm
Actuates a routing flap on a packaging line, using the CA clevis to pivot and push parcels weighing up to 8 kg smoothly across a 450 mm arc.
Textile Loom Tensioner
Extends a tensioning guide bar through a 450 mm cycle, relying on the 157 N push force at 0.5 MPa to maintain fabric tightness in humid dyeing rooms.
Pallet Labelling Gate
Swings a labelling head into position via the rear pivot mount, utilizing the stainless steel construction to withstand dusty warehouse environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CA the Right Cylinder?
Sizing this 20 mm bore against its neighbours shows a clear step in capability: the smaller 16 mm bore yields 100.5 N of push at 0.5 MPa, while the larger 25 mm bore jumps to 245.3 N. This model sits comfortably in the middle for medium-force tasks. Because this is a 450 mm stroke, keep side-load forces minimal to prevent rod bending over that long extension distance.
The CA rear pivot cover suits angular movement applications. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches; you would need the -S variant for sensing. Furthermore, the fixed bumpers only decelerate the end of stroke and do not function as a brake, so an external rod lock or pilot check valve is required if the load must be held vertically when air pressure drops.
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 MI20X450CA FAQ
This 20 mm bore cylinder features a 1/8 inch port and generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG or EMSG switches. You must select the -S magnet variant to enable magnetic sensing on the stainless-steel round body.
