About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCMLB
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 25 mm strokes with precision. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its 1/8" port and M8x1.25 male rod thread make integration straightforward.
Featuring an integrated piston magnet, the unit supports CMSG, DMSG and EMSG switches for position sensing. The ISO 6432 mounting interface ensures it drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCMLB Is Used
Clamping Small Housings
Holds aluminium die-cast parts securely during CNC drilling operations using its 157 N push force.
Flap Folding
Actuates a short 25 mm stroke to tuck cardboard carton flaps before sealing on a packaging line.
Lab Dispenser Push
Depresses liquid pump heads in automated chemical dispensing rigs where stainless steel resists moisture.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X25SCMLB the Right Cylinder?
When sizing this actuator, stepping down to a Ø16 bore yields 100.5 N push at 0.5 MPa, while moving up to a Ø25 bore provides 245.3 N. This model includes an LB foot bracket and a CM round rear cover for stable base mounting. Because the stroke is a brief 25 mm, rod bending is negligible, but always keep the load axially aligned to prevent guide wear.
The fixed TPU bumper pads decelerate the piston near the stroke ends but do not act as an adjustable air cushion. If your process requires the rod to stay put during a pressure drop or valve centre, this cylinder will drift; you should fit an external rod lock or a pilot-operated check valve to secure the load.
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 MI20X25SCMLB FAQ
This 20 mm bore cylinder features a 1/8" port. It delivers 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 of 32 kgf at 1.0 MPa.
Yes, the built-in magnet allows CMSG, DMSG and EMSG switches. The LB foot bracket provides stable base mounting, while the CM round end cover dictates the rear port orientation.
