About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 130 mm stroke with ease. The riveted barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The U suffix equips the rear with a 90-degree back cover for versatile port and pivot routing. Fixed TPU bumper pads absorb the impact at stroke end to protect the mechanism. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 8 kg safe vertical lift capacity to swing the guide and redirect boxes into secondary lanes.
Lab Sample Ejection
Pushes processed test tubes out of a centrifuge carousel in humid laboratory environments, relying on the stainless steel construction to prevent mild corrosion.
Tote Pusher Assembly
Cycles at 130 mm to push plastic totes onto an outbound roller track, utilizing the 90-degree U cover to optimize rear mounting clearance.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X130SU the Right Cylinder?
When sizing this actuator, note that stepping down to a 16 mm bore drops the 0.5 MPa push force to 100.5 N, while moving up to a 25 mm bore increases it to 245.3 N. The 130 mm stroke is well within the 500 mm maximum for this bore, keeping the unit standard. The included -S magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position detection.
Remember that the TPU bumpers only decelerate the piston near the stroke end; they do not function as a lock. If your application must hold a load vertically during air loss or valve centering, the piston will drift, so you should add an external rod lock or a pilot-operated check valve.
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 MI20X130SU FAQ
This 20 mm bore cylinder features a 1/8 inch air 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 force of 32 kgf at 1.0 MPa.
The fixed TPU bumpers only decelerate the stroke end and do not lock the piston, so the rod will drift if air is lost; use an external pilot check valve for holding. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing.
