About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore features a 1/8" port and an M8x1.25 male rod thread. Its U-type back cover provides a 90-degree port orientation, simplifying lateral hose routing in tight machine cells. Built with a riveted stainless barrel and rod, it resists mild corrosion and washdown better than painted alternatives.
The fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning. Because this SKU lacks a magnet, it cannot host CMSG or DMSG switches; add an -S variant if you need position sensing. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50U Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using its 157 N thrust to push cartons onto secondary lanes.
Small Press Ejector
Kicks stamped micro-components out of a die bed, utilising the 50 mm stroke and U-cover for side-mounted air connections.
Bin Lid Lifter
Raises hinged covers on material hoppers, safely lifting loads around 8 kg vertically thanks to its robust stainless build.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50U the Right Cylinder?
When sizing this 50 mm stroke unit, consider the neighbouring bores: the Ø16 generates 100.5 N push, while the Ø25 yields 245.3 N at 0.5 MPa. If your load requires holding position during air loss or valve centering, note that the piston will drift; the bumpers only decelerate the end of stroke and act as neither a lock nor a brake. You must integrate an external pilot check valve or rod lock for secure suspension. Furthermore, this non-magnetised version cannot accept sensors, so switch to the -S model if your control system requires end-of-stroke detection.
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 MI20X50U FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it delivers 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. This Ø20 mm bore uses a 1/8" air port and an M8x1.25 male rod thread.
Yes, it uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. However, because this specific SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG sensors; you must specify the -S variant for position detection.
