About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCMLB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 300 mm stroke 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 settings. Built-in fixed TPU bumper pads soften stroke-end impacts, while the riveted construction keeps the body compact.
For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The -S suffix means a piston magnet is included, allowing direct mounting of CMSG, DMSG, or EMSG switches for position sensing. The CM round end cover and LB foot bracket provide stable base mounting.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCMLB Is Used
Package Diverting Gate
Actuates a routing flap on a 300 mm stroke to redirect small to medium parcels on a packaging line, utilizing the 157 N push force to overcome flap friction.
Textile Loom Tensioner
Adjusts yarn tensioning rollers in humid textile manufacturing environments, where the stainless steel rod prevents mild corrosion from ambient moisture.
Bin Lid Automation
Opens and closes heavy composite storage bin lids, safely lifting components weighing up to 8 kg vertically through the integrated LB foot mount and CM round end.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300SCMLB the Right Cylinder?
When sizing this 300 mm stroke model, verify side-load forces, as the extended Ø8 mm rod is more susceptible to bending over longer distances. If your application requires less push, the Ø16 bore offers 100.5 N at 0.5 MPa; for heavier loads, stepping up to the Ø25 bore provides 245.3 N. Because the standard MI series uses fixed TPU bumper pads rather than an adjustable cushion, consider the MIC variant for high-speed operations requiring end-deceleration tuning.
This SKU includes the LB foot mount and CM round end cover. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 MI20X300SCMLB FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. The double-acting thrust is 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the Ø20 mm bore uses the ISO 6432 mini-cylinder mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. Additionally, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG reed or electronic switches for precise position detection.
