About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300CM
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 a CM round end cover. The 1/8" port feeds the 8 mm piston rod, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. Its riveted stainless barrel shrugs off mild corrosion, outlasting painted alternatives in damp production areas.
For real work, plan around 94 N of usable load at 0.5 MPa, which translates to lifting an 8 kg part vertically with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors. The Ø20 body conforms to ISO 6432 mounting dimensions, ensuring it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300CM Is Used
Packaging Line Diverter
Pushes light cartons at 157 N on a packaging conveyor, using the 300 mm stroke to shift products cleanly between adjacent belt lanes.
Textile Loom Tensioner
Moves a yarn guide bar through a 300 mm cycle, relying on the stainless steel barrel to resist humid textile mill environments.
Bin Lid Actuator
Raises and lowers access hatches on storage bins, where the CM round end cover and ISO 6432 dimensions simplify rear pivot mounting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X300CM the Right Cylinder?
When sizing this 300 mm stroke unit, the neighbouring Ø16 bore provides 100.5 N of push at 0.5 MPa for lighter duties, whereas stepping up to the Ø25 bore yields 245.3 N for heavier loads. A 300 mm extension on an 8 mm rod demands careful alignment; excessive side loading will bend the rod, so utilize FA flange or TC trunnion mounts to preserve straight tracking. To sense piston position, you must select the -S magnet variant, as this base configuration cannot accept a switch.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the end of travel and act as neither a brake nor a lock. To suspend a vertical load safely during an air loss event, fit an external pilot-operated check valve or a dedicated rod lock.
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 MI20X300CM FAQ
This 20 mm bore cylinder features a 1/8" 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 of 32 kgf at 1.0 MPa.
No, this specific SKU lacks an internal magnet and cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for position sensing. The unit uses fixed TPU bumper pads for end-of-stroke deceleration and follows ISO 6432 mounting dimensions.
