About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X40CMLB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Built with fixed TPU bumper pads to soften stroke-end impacts, the riveted construction keeps the unit compact and light.
Because it conforms to ISO 6432 mounting dimensions, this Ø20 mm unit drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for a safe working load of about 94 N, which means it can lift roughly 8 kg vertically with a 2:1 safety margin. This specific configuration includes a CM round end rear cover and an LB foot mounting accessory.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X40CMLB Is Used
Package Diverting Gate
Pushes lightweight cardboard cartons on a packaging line using its 157 N push force, with the LB foot mount stabilizing the actuator against lateral deflection.
Damp Environment Ejector
Ejects machined plastic parts from a coolant-washed zone, leveraging the stainless steel barrel and rod to prevent mild corrosion where painted cylinders fail.
Small Parts Clamp
Clamps aluminium workpieces during a light drilling cycle, safely handling loads near the 94 N safe working threshold at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X40CMLB the Right Cylinder?
When sizing this 40 mm stroke actuator, compare it against adjacent bores: the smaller Ø16 mm generates 100.5 N of push at 0.5 MPa, while the larger Ø25 mm provides 245.3 N. Choose this Ø20 mm model when your application requires roughly 157 N of push force. The included LB foot bracket secures the body firmly, while the CM round end cover dictates the rear port orientation. Keep in mind that air pressure both extends and retracts the rod in this double-acting design.
Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches; you must upgrade to an -S variant for sensing. Furthermore, a plain cylinder drifts if air pressure drops or the valve is centred—the TPU bumpers only decelerate the stroke end and do not act as a lock. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve.
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 MI20X40CMLB FAQ
This Ø20 mm bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. It generates 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, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet (-S), so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The unit relies on fixed TPU bumper pads to decelerate the stroke end and uses an ISO 6432 mounting interface for standard brackets.
