About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SUH
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 75 mm stroke with a robust riveted construction. The integrated piston magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position feedback. A U-type 90-degree rear cover provides flexible mounting orientation, while the Viton (FKM) -H seal option extends reliability in elevated temperature environments.
Because the 1/8" port and M8x1.25 male rod thread match standard ISO 6432 mounting dimensions, this unit drops seamlessly into existing mini-cylinder brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown better than painted alternatives. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SUH Is Used
Diverting Gate Actuation
Pushes light routing flaps on packaging conveyors where the 157 N force and 75 mm travel precisely redirect small cartons without mechanical stress.
Heat-Seal Jaws
Ideal for operating small thermal sealing jaws in film packaging equipment, leveraging the Viton -H seals to withstand ambient radiated heat near the sealing bars.
Textile Loom Tensioning
Maintains proper yarn tension on automated looms, using the stainless construction to resist humid textile-mill environments and the 90-degree U cover for tight clearances.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SUH the Right Cylinder?
When sizing this 20 mm bore, stepping down to the 16 mm variant reduces the 0.5 MPa push force to 100.5 N, whereas moving up to the 25 mm bore increases it to 245.3 N. The fixed TPU bumper pads decelerate the piston at the stroke ends but do not act as a lock; if air pressure drops or the valve is centered, the rod will drift. To maintain vertical position under load loss, install an external rod lock or a pilot-operated check valve.
This specific SKU includes the -S magnet for electronic or reed switches and the -H high-temperature Viton seal. The 75 mm stroke is well within the 500 mm maximum standard stroke for this bore, minimizing rod-bending side-load risks while offering excellent travel for compact assemblies.
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 MI20X75SUH FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push and 131.9 N of pull. At 0.7 MPa, push is 219.8 N and pull is 184.7 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The air port is 1/8", the rod diameter is 8 mm, and the male rod thread is M8x1.25.
No, the fixed TPU bumper pads only decelerate the piston at the end of the stroke and do not function as a brake. If air is lost, the rod will drift. To hold a vertical load securely, you must add an external rod lock or a pilot-operated check valve to the system.
