About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles robust actuation tasks. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its riveted round body features a built-in piston magnet, enabling direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
The stainless-steel barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb end-of-stroke impact without adding bulk. For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which means it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SR Is Used
Package Deflector
Pushes lightweight cardboard cartons on a packaging line using the 157 N thrust, with the R axial port keeping hoses neatly routed along the conveyor frame.
Lab Sample Ejector
Ejects plastic test tube racks from a testing carousel; the stainless build tolerates occasional chemical splashes during daily washdowns.
Small Parts Sorter
Diverts aluminum fittings into a reject bin, utilizing the 75 mm stroke and DMSG sensors to confirm the diverting arm position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X75SR the Right Cylinder?
When sizing this 75 mm stroke actuator, compare it against adjacent bores: the smaller Ø16 generates 100.5 N push, while the larger Ø25 provides 245.3 N at 0.5 MPa. The built-in magnet (-S) allows seamless sensor integration. Its R back cover supplies an axial-in port orientation, simplifying plumbing in tight spaces.
Because it is a standard double-acting cylinder, the piston will drift if air pressure is lost or the valve is centered; the TPU bumpers only soften the stroke end rather than locking the load. For vertical applications requiring position holding, incorporate 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 MI20X75SR FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8 inch.
No, it uses fixed TPU bumper pads to decelerate the piston at the stroke ends. It conforms to ISO 6432 mounting dimensions for standard brackets, and the -S magnet supports CMSG, DMSG, and EMSG sensors.
