About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X215SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles mid-range automation tasks with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread, while the 215 mm stroke falls well within the 500 mm standard limit. Its riveted round-body construction shrinks the footprint compared to bulkier alternatives, and the stainless barrel resists mild corrosion in damp environments.
The integrated piston magnet supports CMSG, DMSG and EMSG switches for precise position detection. Fixed TPU bumper pads absorb the impact at stroke extremes without the tuning hassle of an adjustable cushion. For practical sizing, plan for a safe working load of roughly 94 N, which means it can vertically lift about 8 kg with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X215SU Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 215 mm stroke to shift parcels cleanly between sorting lanes.
Textile Loom Tensioner
Maintains consistent yarn tension in a damp textile facility, relying on the stainless steel rod to withstand high-humidity washdowns.
Pallet Label Applicator
Extends a pneumatic applicator head across a pallet face, using the U cover to keep the 1/8 inch air line neatly oriented at 90 degrees.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X215SU the Right Cylinder?
When sizing this unit, the smaller Ø16 bore generates 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N, so the Ø20 sits perfectly in the middle for 157 N applications. The U-style back cover provides a 90-degree port orientation, easing hose routing in tight machinery. Because the 215 mm stroke is relatively long for a mini cylinder, ensure your mounting configuration prevents rod side-loading and bending.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a load safely during an outage, fit 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 MI20X215SU FAQ
This Ø20 mm bore cylinder features a 1/8 inch 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.
Yes, the Ø20 bore utilizes the ISO 6432 mini-cylinder mounting interface, dropping directly into standard brackets and clevises. The -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed and electronic switches along the body.
